Heat decides the season
The best time to visit Las Vegas depends on how much you plan to do outside. The Strip is a long walk between resorts, and the sun is strong. From June to September the average daily high is between 34.9 and 40.3 °C (95 to 105 °F). July and August nights stay around 27 to 28 °C (81 to 82 °F), so the evenings do not cool down much.
March, April, October and November have lower averages and suit long days on foot better. Do not assume spring and autumn are always mild. May already averages above 31 °C (89 °F), and September comes close to 35 °C (95 °F). Winter is the cool season, with highs of 14 to 17 °C (57 to 63 °F).

Summer: June to September
Plan outdoor walks for the early morning or late evening and book air-conditioned stops in between. Indoor shows and aquariums are easier in this heat. The free outdoor sights are still open, so go when it is cooler.

These months have lower averages than summer and suit long days on foot. Evenings are the cooler part of the day. Pack a light jacket for November nights, when the average low is 8.5 °C (47 °F).
Winter: December to February
Days are cool, with highs from 13.8 to 17.2 °C (57 to 63 °F), and nights drop close to 4 to 7 °C (40 to 44 °F). February has the highest average rainfall of the year at 20.3 mm. Bring layers for outdoor sights such as the Bellagio fountains.
