It’s extremely hot outdoors in Las Vegas in August, but they’re always pumping the AC at most indoor spots. We’re used to the heat as locals (70s feels cold to us), but it isn’t the most ideal time of year for visitors.
Unfortunately, it’s still a popular time to visit especially for families, so hotel rates aren’t any lower.
