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 110 degree F plus temperatures. The area generally has less than five inches of annual rainfall. Water temperatures may range from 45 degrees F. to 85 degrees F. during winter and summer respectively.
