Month-by-month weather, the cheapest weeks to book, and the dates to avoid.
The two best stretches are mid-March through May and mid-September through November. You get warm days, cool-enough nights, and room rates that aren't set for a convention crowd. Winter is the cheapest time to sleep on the Strip. Summer is the hottest, and midweek in July it's often cheaper than winter — if you can handle 105 degrees.
Below is what each season actually feels like, the weeks rooms cost the most, and the best month for the kind of trip you're taking.
Spring (March to May): highs climb from the low 70s in March to the low 90s by late May. Nights stay in the 50s and 60s. This is the most comfortable stretch of the year for walking the Strip.
Summer (June to August): daytime highs run 100 to 110. July averages a high near 105, and the pavement makes it feel hotter. Nights only drop to the mid-80s. Plan on being indoors or in a pool from noon to 5pm.
Fall (September to November): September still runs mid-90s. October cools to the low 80s. By November days sit around 65 and nights drop into the 40s. October is a lot of people's favorite month here.
Winter (December to February): highs of 55 to 60, nights near 40, and it gets windy. You won't swim in an unheated pool, but you can walk all day without sweating through your shirt.
January and February are the low season. After the first week of January, midweek rooms on the Strip drop to some of the lowest rates of the year. February is similar, minus one weekend (more on that below).
High summer — mid-July through August, Sunday through Thursday — is the other bargain window. The heat scares people off, so a room that runs $220 on a March Saturday can fall under $80 on a July Tuesday.
The pattern under all of this: Sunday through Thursday is always cheaper than Friday and Saturday, in every month. Shift your trip one day earlier and you'll often save more than any promo code.
A handful of dates fill the city and push rates up. If your trip is flexible, these are the ones to dodge:
Most Strip pools open in March and close in late October. Dayclubs — Encore Beach Club, Marquee, Wet Republic — run their loudest from May through September. If a pool scene is the point of your trip, come between Memorial Day and Labor Day.
Two exceptions worth knowing: Stadium Swim at Circa downtown is heated and open year-round, and a few resort pools keep one heated pool going through winter. Our pool guide has the full list.
On a budget: January or February, midweek. Or high summer midweek if the heat doesn't stop you.
For the pools and dayclubs: May through September.
For walking, sightseeing, and eating your way down the Strip: March, April, October, and November. Warm days, no heat exhaustion.
Traveling with kids on summer break: June through August. You're locked into the heat, so book a hotel with a pool you'll actually use, and plan indoor mornings.
A couples trip: April and October hit the sweet spot — warm evenings, patios open, rates lower than peak.
Once you've picked your dates, the next call is where on (or off) the Strip to stay — that's covered in where to stay in Las Vegas. Remember that nearly every resort adds a nightly resort fee of $35 to $55 on top of the room rate.
January and February, midweek (Sunday through Thursday), after the first week of January. Midweek dates in July and August also run cheap because of the heat.
July, with average highs near 105°F and nights in the mid-80s. June through August all sit above 100 most days.
Most pools open in March and close in late October, and dayclubs peak May through September. Stadium Swim at Circa downtown is heated and open year-round.
New Year's Eve, CES week (early January), Super Bowl weekend, EDC (mid-May), the Formula 1 Grand Prix (mid-to-late November), and National Finals Rodeo (early December).
April or October — warm days, cool nights, and rates below the summer and event-week peaks.
