Summer in Las Vegas

Summers in Las Vegas are exceptionally hot, with average daytime temperatures often exceeding 100°F. However, the heat is usually dry (considered dry heat), and humidity levels remain low.

The monsoon season, from late July to late August, brings sudden torrential downpours that can lead to flash flooding. These storms can originate from the mountains miles away and leave unexpected flooding in some areas of the city. However, they usually only affect certain parts of the city, leading to a phenomenon where one side of a street might be flooded while the other remains dry.
