Do I Need A Jacket In Vegas In December?
Yes, you need a jacket for Las Vegas evenings in December. Average highs of 56.9F drop to 39.6F overnight, and sunset lands near 4:31 pm on Christmas Day. Here is what to wear on the Strip at night.
Do I Need A Jacket In Vegas In December?
Yes, you need a jacket in Las Vegas in December, and you will want it every evening. The National Weather Service normals for the city put the average December high at 56.9F and the average low at 39.6F, and sunset arrives near 4:31 pm on December 25. Anyone standing on an open-top bus deck, a heliport tarmac or a sidewalk between light displays after dark will feel that drop quickly.
The short version is that Las Vegas in December is a two-outfit city. Daytime, especially in the sun, feels genuinely pleasant: mid-50s on average, dry air, and bright desert light bouncing off the glass towers. Locals eat lunch outside in December. Then the sun goes down, and it goes down early, earlier than almost anywhere a visitor from the southern US or Europe expects. By the time the light displays switch on at 5 pm, the air has already been cooling for half an hour, and the temperature keeps sliding toward that 39.6F average low through the evening.
The people who get caught out are the ones who packed for a casino. Inside the resorts it is a steady, climate-controlled 72-ish degrees, so a whole evening can pass in shirt sleeves if you never leave the building. But the December attractions that draw people to this city at this time of year, the drive-through lights, the open-top bus rides, the night flights, the walk-through gardens, are all outdoors, and they all run after sunset by design. Lights look better in the dark.
That is the real answer to this question. It is not "is Las Vegas cold in December", it is "what am I actually doing at 7 pm". If the answer involves being outside, the jacket comes with you. If the answer is a show and a dinner inside one resort, you can leave it in the room and regret nothing.
For the evenings that are outside, these are the three ways to see the city lit up that this site covers in depth, and all three reward a warm layer:
What Are December Temperatures Really Like?
December in Las Vegas averages a high of 56.9F and a low of 39.6F, based on the 1991 to 2020 climate normals recorded at Harry Reid International Airport. The record low for the month is 11F, set on December 23, 1990, so cold snaps are possible, but the typical pattern is mild afternoons and 40-degree nights. Precipitation averages about half an inch across roughly three days.
Those normals come from the official station at the airport, the same data the National Weather Service office in Las Vegas publishes in its temperature overview for the region. They are 30-year averages, which means any given December day can run warmer or cooler, but they describe the shape of the month well: afternoons that feel like late autumn in most of the US, nights that feel like winter anywhere.
What the averages hide is the speed of the change. The desert has very little humidity to hold the day's heat, so the drop from afternoon high to evening chill is steep rather than gradual. A 3 pm walk to the Bellagio fountains can feel almost warm in direct sun. By 6 pm the same stretch of sidewalk is in the low 40s, and by 9 pm it is close to the overnight low. The sun also sets remarkably early: 4:26 pm on December 1, 4:29 pm on the solstice, and about 4:31 pm on Christmas Day. The lights at every display in the city switch on at 5 pm precisely because the sky is already dark by then.
Here is how the three winter months compare, using the same official normals:
| Month | Average high | Average low | What it means for clothing |
|---|---|---|---|
| November | 67.1F | 47.3F | Light jacket for evenings, often unnecessary by day |
| December | 56.9F | 39.6F | Jacket every evening, layers for daytime transitions |
| January | 58.5F | 40.5F | Nearly identical to December, same packing list |
One more number worth knowing: the record low of 11F. Cold snaps of that severity are rare, but Arctic air does reach the Mojave some Decembers, and when it does, the evening temperature can fall well below freezing. Checking the forecast a day or two before you pack is the only reliable defense, because the gap between a normal December and a cold-snap December is the gap between a light jacket and a real coat.
How Cold Does The Strip Feel After Sunset?
After sunset, the Strip typically sits in the low to mid 40s F, sliding toward the upper 30s late at night. The official normals do not publish an hourly Strip temperature, but the physics are simple: the December low of 39.6F arrives overnight, and most of that cooling happens in the first hours after dark. Anyone outdoors between 6 pm and midnight should dress for the 40s, not for the afternoon high.
There is a second factor that the thermometer does not capture, and it matters more on Las Vegas Boulevard than in most cities: wind channeling. The Strip is a canyon of towers, and the gaps between resorts funnel moving air. The city's own climate data does not publish a Strip-specific wind figure, so treat this as a planning observation rather than a statistic: on breezy nights, the felt temperature along the open stretches, near the High Roller, along the LINQ Promenade, on the pedestrian bridges, runs noticeably colder than the sheltered casino floors you just left.
This is exactly the scenario the open-top bus exists for, and exactly why the jacket question matters for it. The Open-Top Bus Night Tour, a year-round sightseeing ride that runs during Christmas week, puts you on an uncovered upper deck for 2 to 3 hours depending on the tour selected. It is suspended on December 25, 2026, so it is a plan for another night of the week, and on any December night the upper deck at 8 pm is one of the coldest seats in the city. Riders who booked it report the same thing in review after review: bring more than you think you need. It runs from $59 per person with free cancellation up to 24 hours before start, and you can Check availability alongside our open-top bus guide.
The same logic applies to waiting. Queues for shows, rideshare pickup zones, the monorail platform stairs, all of them are outdoor standing time in 40-degree air. A jacket that is tied around your waist during the day becomes your best decision of the night at 9 pm outside the theater.
What Should You Wear On An Open-Top Bus Night Tour?
Dress for the low 40s and plan for two hours of seated, stationary exposure. That means a real jacket, ideally wind-resistant, plus long trousers and closed shoes. A hat and gloves are not unreasonable. The bus moves at city speed with no roof overhead, so the airflow across the upper deck adds to the chill even on a calm night.
Seated stillness is the key word. Walking generates body heat; sitting on an open deck at 15 mph does not. The 2 to 3 hour duration, depending on the tour selected, is long enough that an underdressed rider gets genuinely cold rather than briefly uncomfortable. The 4.2 rating across 3,928 reviews suggests most people love the experience, and the complaints that do appear cluster around exactly this: December riders who showed up in a hoodie.
A practical layering list for the deck:
| Layer | What works | Why |
|---|---|---|
| Base | Long-sleeved shirt or light fleece | Casino interiors stay warm, so the base must be comfortable indoors too |
| Outer | Wind-resistant jacket with a collar | Blocks the moving air across the open deck |
| Legs | Long trousers, not shorts | Seated legs get cold first on an open vehicle |
| Extras | Hat, thin gloves, scarf | Small items, large comfort gain over 2 to 3 hours |
The reward for dressing properly is real. The night skyline from the upper deck, the lit resorts, the glow over Fremont, is a different view than the sidewalk gives, and in December the air is crisp and clear in a way summer riders never experience. Visibility in the desert winter is usually excellent.
Do You Need A Jacket For A Night Helicopter Flight?
Yes, and for a different reason than the bus: the 12-Minute Strip Helicopter runs from a heliport you meet yourself, with no transfers, so you stand on the tarmac before and after the flight. The flight itself is short, about 12 minutes, from $99 per person, rated 4.6 across 2,165 reviews. Check-in and boarding happen outdoors, and December tarmac time at night is genuinely cold. If you'd rather pair the flight with a meal, the guide to helicopter dinner tours over the Strip explains how the optional dinner add-on actually works.
The helicopter cabin is heated, so the flight itself is comfortable in shirt sleeves. What catches people is the ground time. This listing has no hotel pickup, you meet at the heliport, which means arriving, checking in, receiving the safety briefing and waiting for boarding while standing on pavement in the open air. On a December night that is 40-degree exposure for a stretch of 20 to 40 minutes, dressed for a heated cabin. The full index of guides sits on Christmas In Las Vegas.
The fix is simple: wear the jacket to the heliport and stow it or wear it in the cabin. Operators run the 12-Minute Strip Helicopter year-round, and it operates during Christmas week, though Christmas Day operation is not stated on the listing, so confirm your date when booking. Free cancellation applies up to 24 hours before start.
A related option is the Helicopter Night Flight with Optional Dinner, a 10 to 12 minute flight that stretches to 1 to 2 hours door to door, rated 4.3 across 5,914 reviews, also from $99 per person. Its cancellation window is tighter, free cancellation up to 4 days before start, which is worth knowing before you lock a December date. Our night helicopter flights guide compares the two in detail.
What About Daytime And Indoor Plans?
Daytime in December Las Vegas averages 56.9F under usually sunny skies, which many visitors find pleasant enough for a light jacket or even none in direct sun. Indoors, the resorts hold a steady climate-controlled temperature, so a full day of casinos, shows and restaurants needs almost no cold-weather gear at all. The jacket question is really an evening question.
The mistake is planning a day that crosses the sunset line without a plan for it. Sunset near 4:31 pm on December 25 means a 4 pm coffee becomes a 5:30 pm walk in the dark and cold. Anyone whose itinerary moves from indoor to outdoor in the late afternoon, say a museum followed by the Fountains of Bellagio, or shopping followed by a light display, needs to carry the jacket from the start rather than retrieving it from the hotel.
The Christmas-specific attractions make this crossing unavoidable, because they are all evening products by design. Glittering Lights at Las Vegas Motor Speedway opens nightly at 5 pm from November 6, 2026 to January 3, 2027, and it is a drive-through, so the exposure is limited to the walk from the parking area, but the Lights Drive With Pickup tour that visits it, from $75 per person, includes about 1 hour 45 minutes of touring with pickup at the Treasure Island bus zone, and portions of that experience happen outside the car. It is a holiday-themed tour, one of the few genuinely Christmas products on the roster, and it has one review so far, so judge it on the itinerary rather than the rating. For another outdoor holiday activity that pairs well with an evening lights tour, our guide to ice skating in Las Vegas at Christmas covers the rinks that open each winter.
Daytime attractions are the opposite story. A December afternoon at the pool is off the table, but walking the resort corridors, seeing a matinee, or touring the Neon Museum in daylight hours are all comfortable in a light layer. The Neon Museum Plus Open-Top Bus combination, 3 hours from $84 per person, splits the difference: museum time first, then the open-top bus after dark, which means it crosses the sunset line mid-tour and demands the full evening kit.
What Should Families Pack For Christmas Week?
Families should pack one warm layer per person for every evening, sized for low-40s temperatures, plus a spare for children, who feel cold faster when standing still at light displays. The essentials are the same as the adult list, jackets, long trousers, closed shoes, with hats and gloves as cheap insurance for kids waiting in lines.
Christmas week in Las Vegas is a family destination in a way the city is not at other times of year, and nearly all of the family programming is outdoors and after dark. The North Pole Express train in Boulder City runs Saturdays and Sundays from November 28 to December 20, 2026, with 5 pm and 7 pm departures, adults $35 and kids $30, and it includes about 30 minutes of train ride plus activities at Santa's Railyard, some of it standing around in the open. Enchant at Las Vegas Ballpark, November 20 to December 27, 2026, from $25 on the official site, is a walk-through light maze that families typically spend a couple of hours in. Magical Forest runs select nights from November 27 to January 1, closed December 25, with its 2026 ticket price not yet announced. For another after-dark spectacle, see whether the Sphere lights up nightly and how to catch the Strip glowing from above.
The packing math for parents is straightforward. Children at a light display are doing exactly the thing that gets adults cold: standing, walking slowly, staying out for hours after sunset. A kid who was warm in the car at 5 pm is a cold kid at 7 pm. Layers they can remove indoors solve both directions of the problem, since resort interiors and the car will be warm.
A family evening checklist that has held up across every December attraction in the city:
- One insulated or wind-resistant jacket per person, worn or carried from the hotel
- Long trousers and closed shoes, the displays are mostly paved but cold ground radiates chill
- Hats and thin gloves for children, small enough to pocket when not needed
- A spare layer in the car for the drive-through displays, where you stay warm but the walk from parking is not
- Nothing bulky, because casino and mall interiors stay warm and a coat check does not exist everywhere

Does It Ever Rain Or Snow In Las Vegas In December?
Rain is uncommon but real, about half an inch across roughly three days in an average December, and snow in the city itself is rare. What is not rare is snow within driving distance: Mount Charleston and the Spring Mountains sit at high elevation and typically hold a snow season from late November into March, which is why snow day tours exist on the roster.
The rain number matters less for its total than for its timing. Three wet days a month means the odds of any given evening being rained out are low, but December storms do arrive, and the outdoor light displays mostly run rain or shine by policy. Glittering Lights states it is open "rain or shine or holidays." The practical takeaway is that the jacket should ideally be water-resistant, because a 40-degree evening plus light rain is the most miserable combination the month can produce, and it is entirely avoidable with the right outer layer.
Snow in the valley is a different story from snow near it. When cold storms pass through, the Spring Mountains west of the city turn white while the Strip stays dry, and the Mt. Charleston Snow Day Tour, from $175 per person, 5 hours, rated 5.0 from 7 reviews, exists to exploit exactly that gap. It is a self-drive 4x4 rental experience rather than a guided bus tour, and snow depends on conditions, so no operator can guarantee it. For the jacket question, the answer is that a day trip to Mount Charleston in December needs winter gear well beyond a light jacket, while the valley below needs only the standard evening layer. And if you're weighing other ways to spend a December evening in the city, the real per-person prices of tours that replace a limo night in Las Vegas are laid out in a separate guide.
What Kind Of Jacket Is Actually Best?
A wind-resistant, lightly insulated jacket that layers over a sweater or fleece is the single best pick for Las Vegas in December, because it handles the 40-degree evenings, drapes comfortably indoors, and packs small enough to carry during mild afternoons. A heavy parka is overkill for the averages but earns its place if the forecast shows a cold snap.
The reason the middle-weight jacket wins is the indoor-outdoor cycling. A December day in Las Vegas moves between heated casino floors and 40-degree sidewalks a dozen times. A parka that is perfect outside becomes a burden inside, tied to your arm through every restaurant and showroom. A shell with a zip-in or separate fleece handles both worlds, and the fleece alone covers the daytime when the sun is out.
The fabric matters more than the insulation rating. Dry cold in Las Vegas feels different from humid cold, and the wind-resistance of the outer layer does most of the work on the Strip and especially on the open-top bus deck. Water resistance is a bonus for the three-ish rainy days. Beyond the jacket itself, the accessories follow the same logic: a hat and thin gloves weigh nothing and transform a 40-minute outdoor queue, and closed shoes beat anything with airflow.
Before you finalize the packing list, these are the three evening experiences this article has circled, one more time, because they are where the jacket earns its spot in the luggage:
Of the three, the holiday-themed pick deserves a closer look if Christmas lights are the reason for the trip. The Lights Drive With Pickup is the only genuinely Christmas-themed product in the trio, and it pairs the Speedway's 3-mile, 6-million-LED course with a guided ride from the Treasure Island bus zone, which spares you the drive and the parking walk on a cold night.
Common Questions About December Jackets In Las Vegas
Do I Need A Jacket In Vegas In December?
Yes. December averages a high of 56.9F and a low of 39.6F, with sunset near 4:31 pm on Christmas Day, so evenings outdoors run in the 40s. A wind-resistant jacket is the standard recommendation for any night spent outside the resorts.
How cold does Las Vegas get at night in December?
The average overnight low is 39.6F, recorded at Harry Reid International Airport. Evenings on the Strip typically sit in the low to mid 40s before sliding toward that low late at night, and the record low for the month is 11F.
Is Las Vegas warm enough for short sleeves in December?
Daytime, often yes, especially in direct sun, when the mid-50s average high feels milder in the dry desert air. After sunset, no. The temperature falls quickly once the sun drops shortly after 4:30 pm.
What should I wear on the open-top bus night tour in December?
Dress for the low 40s with a wind-resistant jacket, long trousers and closed shoes, plus a hat and gloves for the 2 to 3 hour ride. The upper deck is uncovered and moving air adds to the chill. The tour is suspended on December 25, 2026.
Do I need a coat for the helicopter night flight?
Wear one to the heliport. The 12-minute flight itself is in a heated cabin, but check-in, briefing and boarding happen outdoors on the tarmac, and December nights there are cold. Free cancellation applies up to 24 hours before start.
Does it rain or snow in Las Vegas in December?
Rain averages about half an inch across roughly three days a month. Snow in the city is rare, but the nearby Spring Mountains typically hold snow from late November into March, so a water-resistant jacket is a sensible pick.
