Most people who are unfamiliar with Southern Nevada imagine the area as a scorchingly hot, barren landscape barely suited to human habitation – with the exception of the world-famous Las Vegas Strip. It is of course true that the months of July and August routinely experience temperatures of over 100 degrees but the lack of humidity makes the heat much more bearable. Additionally, every store and restaurant is air conditioned. And many people can choose to spend the day in a pleasantly climate-controlled casino or at the pool in their back yard or neighborhood clubhouse.
On the plus side, during the rest of the year temperatures are on the mild side with a delightfully sunny and mild spring and fall and a cold but quite bearable winter. Again, the lack of humidity makes the cold less damp. Since the average yearly rainfall is only between 4 to 5 inches, family events, sports activities or vacations are never “rained out”.
For those of us who are sun worshippers, Las Vegas has an average of 310 sunny days per year. "Sunny days" in Vegas are considered days when there are no cloud breaks – unlike other cities that consider “sunny days” any day where the sun makes an appearance.
Snow is a welcome rarity in the winter with a light coating of white falling possibly once or twice a year, if at all, in the Valley. However, snow is available in the mountains for skiing and snowmobiling for a good portion of the winter.
These are the average temperatures during the year in Las Vegas:
