July is the hottest month in Las Vegas, and the average highs are at an extreme 104°F (40°C). The rain is sporadic, but there are occasional thunderstorms with heavy spells of rain in the space of a few days. Early mornings and late evenings are better periods to venture out while there is no dearth of indoor activities during the rest of the day.
Spots in indoor swimming pools are hard to find by in the roasting heat and nowhere are the air conditioners as mandatory as in Vegas.
July is a nice time to visit the Mandalay Bay Aquarium with a host of shark species.
