Las Vegas Weather and Average Temperatures

The weather in Las Vegas, Nevada, is part of what makes Las Vegas a successful tourist destination. Las Vegas weather can get very hot, as the city is in a southern desert, but intense heat during the summer months, is not so much of a problem than, say, bitter cold, snow storms, or hurricanes. The upside of a very hot summer is mild weather during the rest of the year, which keeps Las Vegas open for business, all year round.

Because of the Desert terrain, temperatures in Las Vegas drop considerably at night, so unless you go during the summer, make sure you bring some warm clothes. Las Vegas also gets some rain year round.

Las Vegas weather in good enough to keep the hotel/resort pools open from March to October. The summer months of June, July, and August, are hot enough make everyone go to the pool, so things can get crowded.

Summers are of course very hot, but due to desert conditions, there isn't much humidity in the air, and this makes a big difference. Low humidity allows sweat to evaporate more easily, and cool the body down. But hot temperatures are HOT! They can hover around 120 degrees Fahrenheit at times. Thanks god for large, air-conditioned hotels with swimming pools.

The summer is also the rainy season in Las Vegas. Large quantities of precipitation, and nonabsorptive desert soil are also a recipe for flash floods. Las Vegas is also plagued with a major flood about every 10 to 15 years.
