Las Vegas weather by season

Spring (Mar–May) - peak comfort. April averages a 79°F high / 57°F low. Ideal for walking the Strip and day trips.
Summer (Jun–Aug) - hot. July is the hottest month at ~104°F high / 82°F low, with extremes of 113–120°F. Great for pools & dayclubs; save midday for indoor shows.

Winter (Dec–Feb) - mild days, cold nights. December is coldest at ~57°F high / 40°F low, with some nights near freezing.

Summer heat: take it seriously

Highs of 100–115°F make midday outdoor activity risky - heat exhaustion and heat stroke are real. Hydrate, seek shade, and schedule outdoor plans for early morning or evening.

When hotels are cheapest

Base rates are generally lowest in summer and January. But Las Vegas pricing is event-driven: city-wide events such as CES (January 6–9, 2027), the F1 Las Vegas Grand Prix (November 19–21, 2026) and the National Finals Rodeo (December 3–12, 2026) push rates well above seasonal norms.

Quick verdict

Best overall: April or October.
Cheapest base rates: summer / January (heat or chill is the trade-off).
Avoid for value: big convention and event weeks.
