Death Valley is renowned for being one of the driest and hottest places on earth. During the summer temperatures can be 120°F or over. Evenings generally stay around a comfortable 80°F. We recommend that you wear sunscreen, broad-brimmed hats, and always carry water with you.
It is not until October that the heat starts to die down. During the short winters, the temperature is about 65°-72°F during the day. Nights are colder ranging from the mid 30°s to low 40°s. Death Valley gets less than 2 inches of precipitation a year; if there is any chance of rain, it will occur during the winter. We advise that you watch for a flash flood if it does rain. We advise you to check for current forecasts as the weather can fluctuate.
