May in Las Vegas is that sweet spot where the desert really starts to sizzle, but hasn’t yet reached the “don’t touch the steering wheel” heat of July. It’s the official kickoff to the outdoor season, where the pools are packed, the dayclubs are legendary, and the neon lights seem to shine just a little brighter against the warm night air.

We have navigated the Strip during many Mays, and it is easily one of our favorite times to visit. You get all the perks of summer—like the world-famous Electric Daisy Carnival (EDC)—without the 110-degree afternoon slump. Here is our honest, expert guide to Las Vegas weather in May 2026.

Average Temperatures: The Desert’s Warm Welcome

Contents show

In May, the thermometer begins its steady climb toward summer. You can expect daytime highs to start the month around 85°F and finish closer to 94°F. Because Las Vegas sits in the Mojave Desert, the humidity is incredibly low (around 10–15%), which means that even as it gets hot, it stays a “dry heat” that many find more tolerable than the muggy East Coast.

Once the sun sets, the temperature drops to a very pleasant 66°F (19°C). We have found this is the perfect temperature for walking the Strip or sitting at an outdoor patio like Mon Ami Gabi without needing a heavy jacket.

Direct Answer: Las Vegas weather in May 2026 features average highs of 91°F and lows of 66°F. With 13 hours of daily sunshine and almost no rainfall, it is the peak month for pool parties, outdoor dining, and desert exploration.

What to Do: Pool Season and Outdoor Vibes

Because the heat is intense but not yet dangerous, May is the prime time for outdoor “daylife.”

Pool Parties: Every major dayclub—from Encore Beach Club to Wet Republic—is in its prime. Expect A-list DJs like Tiesto and Steve Aoki to headline throughout the month.
EDC Las Vegas: Taking place May 15–17, 2026, at the Las Vegas Motor Speedway, this massive festival brings in over 500,000 “Headliners.” If you aren’t attending, be aware that traffic will be heavy and hotel prices will spike!
Red Rock Canyon: We have always recommended hitting the trails early. By 11 AM, the rocks will be hot, so plan your hikes for 7 or 8 AM to enjoy a comfortable 70-degree climb.

Direct Answer: May marks the heart of the summer event season, headlined by EDC Las Vegas (May 15–17) and Memorial Day Weekend (May 22–25). Travelers should expect high hotel occupancy and energetic pool parties throughout the month.

Our Best Pro Tip: If you want to see the desert at its most beautiful, head to The Springs Preserve. In May, the desert botanical gardens are in full bloom, and the mild breezes make for a perfect afternoon stroll before the true summer heat arrives.

❓ FAQ: Las Vegas Weather In May

Is May a good time for the pools?

It is arguably the best time. The sun is hot enough to make the water feel incredible, but the pavement isn’t yet hot enough to burn your feet instantly.

Does it rain in May?

Hardly ever. May averages only two days of light rain for the entire month. You can safely plan outdoor weddings or tours without worrying about a washout.

Is the sun stronger in the desert?

Yes. The UV index in May is usually “Very High” (9+). Because the air is dry, you won’t feel yourself sweating as much, which can lead to rapid dehydration. You’ll need more water than you expect, so keep sipping all day.
