Sun, More Sun and a Bit of Rain
One of the many aspects of the Lake Mead National Recreation Area that continually draws visitors is its good weather. Many people come just to relax in the land of the sun. Refugees from states hit hard by winter's icy clutch often flee to this area to spend a mild winter. Sunbathers and water skiers spend summers here to toast in the 110F (43C) degree plus temperatures. The area generally has less than five inches of annual rainfall. Water temperatures may range from 45F (7C) to 85F (29C) degrees during winter and summer respectively.
The park is 1.5 million acres, so weather can vary 20-30 degrees from the northern portion to the south. Find current and past weather conditions, including temperatures, winds, wave heights and precipitation using the links below or call the Las Vegas Office of the Weather Service at 702-263-9744.
