Key Highlights:
- The “Sweet Spots”: April, May, September, and October offer perfect 70°F to 80°F days—ideal for walking the Strip.
- The Sizzle: July and August are scorching, with temperatures regularly topping 105°F (40°C).
- The Chill: December and January are the coldest months; days are sunny but crisp (mid-50s), while nights can hit freezing.
- The “Arctic” Factor: Regardless of the month, casinos blast A/C year-round. Always pack a light layer for indoors.
Whether you’re dreaming of a neon-lit pool party or a crisp morning hike at Red Rock Canyon, knowing the Las Vegas weather by month is the secret to a successful trip. Most people assume the desert is just “hot,” but Sin City actually experiences four distinct seasons—including winter nights that can plummet into the 30s.
I’ve stood on the Strip in 115°F heat and walked through the Bellagio Conservatory in a heavy wool coat. Trust me, the climate here will surprise you. In this guide, I’m breaking down the forecast expectations so you can pack the right gear and plan the best activities for your stay.
Spring: The Peak Season (March – May)
Spring is arguably the best time to visit Las Vegas. The botanical displays are at their peak, and the pool season officially kicks off.
- March: Highs of 71°F (22°C). This is prime “walking weather.” You’ll need a light jacket for the evenings, but the days are glorious for outdoor sightseeing.
- April: Highs of 78°F (26°C). This is the “Goldilocks” month—not too hot, not too cold. It’s the absolute best time for hiking the red sandstone peaks of Red Rock Canyon.
- May: Highs of 90°F (32°C). The heat begins to ramp up, and the legendary day clubs at resorts like Encore Beach and Tao are in full swing.
Summer: Surviving the Desert Heat (June – August)
If you visit in the summer, your trip will revolve around air conditioning and hydration. It is a dry, intense heat that feels like standing in front of an open oven.
- June: Highs of 100°F (38°C). The humidity is almost zero, so you won’t feel “sticky,” but you will dehydrate twice as fast as you think.
- July: The hottest month with an average high of 106°F (41°C). It is common to see heat waves push the mercury toward 115°F.
- August: Highs of 104°F (40°C). This is also “monsoon season,” where dramatic, sudden thunderstorms can roll in during the late afternoon, causing spectacular lightning shows over the desert.
Expert Tip: In the summer, only walk the Strip after sunset. During the day, stay indoors or use the free trams (like the Aria-Bellagio loop) to jump between casinos without melting.
Fall: The Locals’ Favorite (September – November)
Once the triple-digit heat breaks in mid-September, the city breathes a collective sigh of relief. This is the best time for rooftop bars and outdoor dining.
- September: Highs of 96°F (36°C). Early September still feels like summer, but the evenings become incredibly pleasant by the end of the month.
- October: Highs of 82°F (28°C). This is many locals’ favorite month. The sky is crystal clear—perfect for the Life is Beautiful festival or outdoor concerts at the T-Mobile Arena.
- November: Highs of 67°F (19°C). The air turns crisp. It’s great for sightseeing, though many smaller hotel pools will begin to close for the season.
Winter: Bright Sun and Cold Nights (December – February)
Don’t let the palm trees fool you—Vegas gets cold. While you won’t see much snow on the Strip, the desert wind can be biting.
- December: Highs of 57°F (14°C). The city is stunning with holiday lights, but lows can drop to 39°F (4°C). You will need a real winter coat for outdoor walks.
- January: The coldest month. It’s bright and sunny during the day, but you’ll want layers for the chilly desert wind.
- February: Highs of 63°F (17°C). Hints of spring begin to appear. If you avoid the Super Bowl rush, it’s one of the quietest and cheapest times to visit.
A Final Pro Tip from a Friend
No matter what month you visit, always bring a sweater. It sounds ridiculous when it’s 105°F outside, but Las Vegas casinos keep their air conditioning at “refrigerator” levels. I’ve seen countless tourists shivering at a blackjack table because they didn’t realize how cold the indoors could be!
