January weather: sunny, cool and cold after dark
January is the coldest month in Las Vegas, but cold is relative in the Mojave. Typical daytime highs run about 57–60°F (14–16°C) and overnight lows sit around 38–42°F (3–6°C). Most days are sunny, with the month averaging roughly eight hours of sunshine, and rain falls on only three or four days in a typical January, usually as a brief winter system passing through rather than an all-day soak. Snow on the Strip is rare enough to make the news; snow on the surrounding mountains is normal and pretty.
What surprises visitors is the swing between day and night. A sunny 60°F afternoon walking Las Vegas Boulevard feels warm; the same walk at 11pm in a breeze feels like 35°F. Wind is moderate this month, but the corridors between tall resorts funnel it, so the pedestrian bridges near Bellagio and Caesars Palace can be surprisingly bitter. Mornings are the crispest part of the day and the best time for Red Rock Canyon, where it is typically five to ten degrees colder than the Strip.
CES: the week that rewrites the price list
The Consumer Electronics Show typically lands in the first half of January and fills well over a hundred thousand rooms across the Las Vegas Convention Center, Venetian Expo and satellite venues. For roughly five nights, midweek rates at Strip resorts can run two to four times their normal January level, minimum stays appear, and popular restaurants are booked out by corporate dinners. Rideshare surge pricing near the convention center is severe in the mornings and evenings. Our CES guide has the full picture.
If you are not attending, avoid the CES dates entirely unless you have a specific reason to be here. The week before CES is often quiet, and the week after it is one of the best-value windows on the whole calendar, because leisure demand has not yet recovered and the convention crowd has flown home. Book those post-CES midweek nights and you can sit in a room at Aria or Wynn for a fraction of the spring rate.
One smaller January event: an adult-entertainment expo and awards weekend typically overlaps or follows CES and adds a little demand at a handful of resorts, though nothing on the CES scale.
Crowds and hotel prices through the month
Outside CES, January is a low-season month. The first few days carry over New Year's Eve pricing and crowds, then the city empties fast. Mid to late January weekdays are among the cheapest of the year at every tier: budget rooms Downtown can drop into the double digits before resort fees, and mid-Strip resorts often price weeknights at half of what they charge in March or October. Weekends still cost more, typically 50–100% above the weeknight rate, but the gap is smaller than in peak months because weekend demand is soft too.
Crowd levels follow the same shape. Casino floors are busy during CES and dead quiet the following week. Shows that sell out in spring have good seats available a few days out, restaurants take walk-ins and the Strip sidewalks are walkable at any hour. The Martin Luther King Jr. holiday weekend, in the second half of the month, brings a modest bump in both prices and crowds, and the last weekend of January sometimes begins to feel Super Bowl demand if the game falls early in February. If you want Las Vegas without the throng, the third week of January is close to the best it gets. See how to get a hotel deal for the timing tactics.
Pool status in January
Most resort pools are closed for the season in January. The big pool complexes at Mandalay Bay, MGM Grand, Caesars Palace and Flamingo typically shut in late autumn and do not reopen until March. A handful of resorts keep one heated pool open year-round, usually with limited hours and no drink service to speak of; Aria, Cosmopolitan, Bellagio, Wynn and a few others have historically kept a heated pool running for hotel guests, but availability changes each year, so check with the resort before you pack a swimsuit with expectations.
What is open is the hot tub and the spa. January is an excellent month for a spa day: the big resort spas at Encore, Caesars Palace and Aria offer day passes to non-guests and are much less crowded than during pool season. For a swimming-centered trip, choose a different month; our best pools guide covers which resorts stay open in winter and how they operate. Dayclubs are closed until spring.
What to pack for January
Pack in layers. A typical January day starts near 40°F, peaks around 60°F in full sun and drops back to 40°F by the time you leave a show. Bring a real jacket, a warm layer that fits under it, and closed shoes; sandals and shorts belong to a different month. Evening wear for nightclubs and fine dining stays the same as in any month, but you will want a coat for the walk or the rideshare queue, and most clubs run coat checks.
- Warm jacket or coat, plus a hoodie or sweater for layering
- Comfortable closed walking shoes; the Strip is four miles end to end
- Sunglasses and sunscreen, because the sun is strong even when it is cold
- Lip balm and moisturizer; the desert air in winter is extremely dry
- Hat and gloves if you plan a Grand Canyon or Red Rock day; both are noticeably colder than the city
- A swimsuit only if you have confirmed your resort has a heated winter pool

The best things to do in January
January is a walking and hiking month. The desert day trips that are punishing in summer are at their best now: Red Rock Canyon scenic loop, the Valley of Fire, and Hoover Dam are all comfortable in the midday sun. Grand Canyon West Rim tours run year-round and the South Rim occasionally has snow on the rim, which is spectacular if you are dressed for it. See our day trips guide.
On the Strip, this is the month to actually see the resorts. The Bellagio Conservatory usually switches from its holiday display to a new seasonal theme in mid-January, which means a few days of closure and then a fresh installation with no crowds. Show tickets are easier and cheaper to get than at any point until August, and the Sphere Experience film has open afternoon slots. The sportsbooks fill for the NFL playoffs every weekend, which is a good excuse to spend a cold afternoon indoors with a beer and a betting slip. Late-January nightlife is quieter, so clubs are more generous with guest lists and tables.
Who January suits
Budget travelers: excellent, as long as you avoid CES. The post-CES week and the third week of January offer some of the lowest room rates of the year, with cheap show tickets to match. Couples: very good. Crisp nights, fire pits at the outdoor bars, open tables at restaurants and spa day passes make it an easy romantic trip, and the lack of pool time is not a loss for most couples in winter.
Families: mixed. Kids get the desert day trips, the free Strip attractions and cheaper rooms, but they lose the pools, which for many families are the daytime plan. Older kids who like hiking will be happy. Conventions: if you are attending CES, book the moment you know you are going, look at off-Strip and Downtown hotels, and expect to walk or use the monorail rather than fight the rideshare queues. Sun seekers: January is not for you; anyone who wants pool weather should look at April or later.
