Set in the heart of the Mojave Desert, Las Vegas has a hot desert climate that is dry year-round and bathed in sunshine more than 300 days a year. Summers are brutally hot, with highs regularly topping 40°C and very low humidity, while winters are mild during the day yet can fall near freezing at night. Annual rainfall is scant, arriving mostly via brief monsoon thunderstorms in July and August.
June through August is peak heat, with daytime highs of 40-44°C. The dry desert air lets sweat evaporate quickly, but the risk of heat illness remains high.
Very little. The city receives only about 100mm of rain a year, most of it from short monsoon thunderstorms in July and August.
Winters are mild with daytime highs around 13-15°C and nights near freezing. Snow within the city is rare, though the surrounding mountains often get it.
Spring (March-May) and fall (October-November) are ideal, offering sunny, dry skies and comfortable temperatures while avoiding peak summer heat.
