The weather is beautiful in the Grand Circle region and the water at Lake Mead is surprisingly warm for most of the season.  It can get pretty hot in July, August and September, so you may want to schedule your vacation for the milder months of May, June or October.  During the summer, it is not unusual for temperatures to exceed 100 degrees farenheit. 

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 5 inches of annual rainfall. Water temperatures may range from 45 degrees F. to 85 degrees F. at different times of the year.

Springtime (March, April & early May) can be cold (you'll need a wetsuit for skiing).  Spring and Autumn weather is highly unpredictable.  The advantage of traveling this time of year is that availability of accommodations and rentals are greater.
