Planning a trip to Nevada requires understanding local weather patterns, as desert conditions create sharp extremes. Temps in Las Vegas by month range from freezing winter desert nights to scorching summer afternoons exceeding 100 degrees Fahrenheit. Spring and autumn bring pleasant warmth, making them the most popular windows for outdoor exploration. Knowing what to expect month by month helps you pack properly and avoid unexpected climate surprises.
Spring: March to May
Spring offers some of the most comfortable weather of the entire year in the Mojave Desert. March begins with daytime highs around 72 degrees Fahrenheit, though nights still drop to a chilly 50 degrees. By May, afternoon readings climb rapidly to an average high of 89 degrees.
- March: Highs near 72°F, lows near 50°F. Crisp mornings give way to comfortable afternoon sunshine, ideal for walking the Strip.
- April: Highs near 79°F, lows near 56°F. Humidity remains very low, keeping the air dry and crisp.
- May: Highs near 89°F, lows near 66°F. Early summer heat starts creeping in by late afternoon.
Summer: June to August
Summer in Las Vegas is notoriously intense. Daytime highs consistently top 100 degrees Fahrenheit from June through August, often pushing past 105 degrees in July. While the dry desert air prevents sticky humidity, the sheer thermal weight requires careful hydration and midday shade. Pools and air-conditioned casinos become the main sanctuaries.
- June: Highs near 100°F, lows near 76°F. Long daylight hours provide maximum sunshine, but afternoon heat is severe.
- July: Highs near 105°F, lows near 81°F. Statistically the hottest month of the year. Nighttime lows barely offer relief, staying warm and heavy.
- August: Highs near 103°F, lows near 80°F. Monsoonal moisture occasionally drifts in from the south, bringing brief humidity spikes or sudden desert storms.
Autumn: September to November
As the heavy summer heat breaks, autumn brings a welcoming cool-down. September still feels warm with a 95-degree average high, but by November, daytime temperatures settle into a comfortable 68 degrees. Evenings turn brisk quickly, requiring layers if you plan to stay out after sunset.
- September: Highs near 95°F, lows near 72°F. Skies are often exceptionally clear, marking the return of comfortable outdoor dining.
- October: Highs near 82°F, lows near 59°F. Widely considered one of the absolute best months for visiting, hiking, and sightseeing.
- November: Highs near 68°F, lows near 47°F. Cool winds arrive, signaling the transition into winter.
Winter: December to February
Winters are short and generally mild, but desert nights turn genuinely cold. Daytime highs hover in the upper 50s and low 60s, while overnight lows frequently dip into the high 30s. Freezing temperatures happen occasionally on winter nights, though snow in the main urban valley is rare.
- December: Highs near 57°F, lows near 39°F. The coldest month of the year, featuring crisp, clear winter days and cold nights.
- January: Highs near 59°F, lows near 40°F. Sunny skies persist, though heavy coats are necessary after dark.
- February: Highs near 63°F, lows near 43°F. Winter storms occasionally bring light rain, marking the wettest month on average.
Practical Strategies for Desert Weather
Navigating desert climates effectively requires more than just checking the thermometer. Because humidity stays low year-round—often hovering between 15% and 30%—sweat evaporates instantly, which tricks the body into feeling less dehydrated than it actually is.
- Hydration Management: Drink water continuously throughout the day, even if you don't feel thirsty. Casinos and dry air accelerate fluid loss.
- Sun Protection: The UV index remains high even during cooler months. Pack broad-spectrum sunscreen and polarized sunglasses.
- Layering for Nights: Desert ground loses heat rapidly after sundown. A heavy winter coat or a light autumn jacket is essential depending on the season.
- Pavement Heat: In peak summer, asphalt and concrete retain intense heat. Sandals can become uncomfortable or dangerous on hot pavement; choose breathable, closed walking shoes.

March through May and October through November offer ideal conditions for hiking Red Rock Canyon or walking the Strip without extreme heat.
How hot does it actually feel on the Strip in July?
While official air temperatures hover around 105 degrees Fahrenheit, radiant heat bouncing off glass buildings, concrete, and asphalt can make open areas feel significantly hotter during peak afternoon hours.
Is it windy in Las Vegas?
Spring months, particularly April, experience the highest wind speeds, driven by seasonal weather transitions sweeping across the open desert basin.
