As they say, it is a dry heat in Las Vegas. This helps somewhat, since high humidity like they have in the Midwest, eastern and southern United States, is really miserable and sometimes life threatening.
Las Vegas has an average humidity of 20% or lower between April and August, the hottest months in Las Vegas, around 10% or less during the hottest times of the day. Every home and building in Las Vegas does have air conditioning, which helps, but sure makes it feel hot when walking outside.
Even though the humidity is low, a person can still easily get heat exhaustion or heat stroke while outdoors. It is important to drink a lot of water while outside, whether working or just strolling down the Las Vegas strip and stay away from alcohol. Being drunk and walking in this heat is very dangerous to the health.
Las Vegas is in the Mojave Desert, one of the hottest places on Earth and certainly the hottest place in the United States. Being so dry, you might think it cools off at night that is not the case during the summer months. The overnight lows are many times in the mid 80s.
