Weather in Phoenix

Best time to visit

The summer period is exceptionally hot in Phoenix and the city attracts fewer tourists during these months. If there was such a thing as a peak time to visit, it would be from September to October when it is cooler. October is also a big month for festivals, from Pagan Pride Day with its rituals and demonstrations, to the city’s own Oktoberfest with plenty of Bratwurst, beer and Bavarian costumes on display.
