Las Vegas is located in the high
Mohave Desert. Deserts are renowned for their extreme daily temperatures and Las Vegas is no
exception to that rule. Summer temperatures soar to over 110F / 43C in the day
to 68F / 20C in the evenings. Winter temperatures range from 60F / 16C in the day to
34F / 1C in the evenings. Humidity is low, producing what people call "a dry heat".
Less than 4 inches of rain fall annually in Las Vegas which makes this a perfect
weather spot for sightseeing and picture taking
and outdoor sports of many kinds.
Fall and Spring are generally breezy and mild, but are also
prone to 'flash flooding' where an inch or more of rain can blanket the valley
in less than an hour and run-off to the lower areas causing major traffic
tie-ups in the process. When driving under these conditions NEVER enter a
large puddle or fast flowing water on a roadway or parking area unless you can
see the bottom or other comparable vehicles making it through safely. Standing
water is often far deeper than it appears. Even many locals who mistakenly
think they can make it, need to be rescued annually from water stranded vehicles.
