Vegas is busy all year-round, but especially during the winter months when the rest of North America comes seeking Nevada’s hot, desert temperatures. Spring and fall temperatures are pleasant, with highs averaging between 69-82°F (20-28°C). Summer is a scorcher, with temperatures reaching 105°F (40°C).
It’s especially busy in Las Vegas during the week between Christmas and New Years’ and also at the end of January when all the conventions are in town. March in Vegas can be total chaos when Spring Break and college basketball hits so, if you want lower prices and fewer crowds, definitely do not come during these times!
