You will find lows in the 30’s (°F) and highs well above 100 (°F) with record highs being near 120 (°F)! You might even find some snow flakes during the winter, but it does not happen very often and almost always melts right away.

In our Las Vegas Dress Guide, we suggest wearing layers to deal with this type of wild weather. The best weather is is April through June with average temperatures in the mid 80’s.  You will also find nice weather in September and October. It is the best time to visit for good weather. June, July and August are the hottest times and a good time to hang around the pools to cool down.
