Las Vegas Weather: What to Expect Year-Round

Why Las Vegas Weather Matters

Las Vegas isn’t just about casinos and shows, it’s a year-round destination with outdoor adventures, festivals, and iconic landmarks like the Bellagio Fountains.

The city’s desert climate means low humidity (often under 30%), minimal rain (less than 5 inches annually), and plenty of sunshine (about 3,817 hours a year, per US Climate Data).

But the weather can vary wildly by season, impacting everything from your wardrobe to your itinerary. Spring and fall are crowd favorites for their comfy temps, while summer is all about pool parties, and winter offers a quieter, budget-friendly escape.

Let’s break it down month by month to help you decide when to book those flights.

Seasonal Vibes: When to Visit

Each season in Las Vegas has its own flavor, so let’s unpack what you can expect and why you might choose one over another, based on insights from the National Weather Service.

Spring (March to May)

Spring is a Vegas fan favorite, with highs ranging from 72°F in March to 90°F in May and lows from 50°F to 66°F. Rainfall is practically nonexistent, especially in April and May, making it ideal for outdoor adventures.

Think hiking in Red Rock Canyon, cruising to Lake Mead, or catching an outdoor show. The weather’s warm but not oppressive, and the crowds are manageable compared to summer. If you’re planning a trip for outdoor activities or festivals, spring’s your jam.

Summer (June to August)

Summer in Vegas is hot: we’re talking 100-104°F hot, with lows still in the 70s or 80s. The monsoon season (July and August) brings a slight uptick in rain, but it’s still minimal (0.4-0.5 inches). This is the time for poolside lounging at spots like The Cosmopolitan or indoor fun like hitting the slots or catching a Cirque du Soleil show.

The low humidity makes the heat feel a bit less brutal, but you’ll want to stay hydrated and avoid midday sun. Summer’s also peak tourist season, so expect bigger crowds and higher hotel rates.

Fall (September to November)

Fall is another golden window, with highs dropping from 94°F in September to 67°F in November and lows from 70°F to 46°F. Rainfall stays low (0.3 inches monthly), and the weather’s perfect for strolling the Strip, golfing, or day-tripping to the Grand Canyon.

October, in particular, is a sweet spot, with warm days, cool nights, and fewer tourists. Fall’s also great for events like food festivals or outdoor concerts, making it a versatile time to visit.

Winter (December to February)

Winter in Vegas is mild by most standards, with highs between 58°F and 64°F and lows in the high 30s to mid-40s. February sees the most rain (0.8 inches), but it’s still drier than most U.S. cities. Snow is super rare in the city itself, though nearby mountains like Mount Charleston might get a dusting.

Winter’s great for budget travelers, with lower hotel rates and fewer crowds, plus epic events like New Year’s Eve on the Strip. Pack a light jacket for evenings, and you’re good to go.

Packing for Vegas is all about prepping for the desert climate and seasonal shifts:

Winter: Pack light layers like long-sleeve shirts, jeans, and a jacket or sweater for chilly nights. Daytime attire can stay casual and light.

Spring and Fall: Go for versatile layers: t-shirts, light jackets, or cardigans work well for warm days and cooler evenings. Comfortable walking shoes are key for exploring the Strip.
