Ten-year averages for this calendar month. A rainy day is one with at least 1 mm of rain, as a weather station counts it. The model these figures come from drizzles more than a rain gauge, the more so the warmer the month, so its days count from 2 mm, rising to 5 mm in the hottest.

Weather read at Heritage Square, downtown, 6 km from the airport (PHX): ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.

How busy it gets

August: about usual. Busiest in March.
