Las Vegas sits in a high-desert basin, so its weather is defined by intense summer heat, mild winters, and very low humidity. The live forecast above gives today’s conditions, but the big picture is a near‑constant absence of rain and more than 300 days of sunshine each year.

How reliable are extended forecasts?
A las vegas weather 14 day forecast can give a general trend, but accuracy drops sharply beyond seven days. Local forecasters also publish a las vegas weather forecast 21 day outlook, though it is best treated as a pattern guide rather than a day‑by‑day prediction. For short‑term plans, a weather in las vegas 10 days outlook is the most dependable source, especially during the hotter months when heat‑wave timing matters.
Does Las Vegas ever get rain?
Yes, but it is infrequent. Average annual precipitation is about 110 mm. Most rain falls in brief, intense showers during the monsoon season (July–September) or as gentle winter storms. Snow is extremely rare.
How hot does it get in summer?
Afternoon highs regularly reach 40–42°C from June to August. Because humidity is very low, the dry heat feels less oppressive than in humid climates, but heat‑exhaustion risk remains high. Always carry water and wear sun protection.
Should I check a 30‑day forecast before booking?
A las vegas weather next 30 days outlook can hint at seasonal shifts but is too uncertain for exact temperatures. Use it to confirm you are packing for the right season, then rely on a 7‑ to 10‑day forecast closer to your trip.
