The city is located within the sunniest region in the world. Measuring 3,872 hours of bright sunshine annually, Phoenix receives the most sunshine of any major city on Earth.[86] Average high temperatures in summer are the hottest of any major city in the United States.[87] On average, there are 107 days annually with a high of at least 100 °F (38 °C)[88] including most days from late May through early October. Highs top 110 °F (43 °C) an average of 18 days during the year.[89] On June 26, 1990, the temperature reached an all-time recorded high of 122 °F (50 °C).[90] Despite the city's claim to the most extreme heat in summer, however, it does not have the highest average annual temperature in the contiguous United States.

Flagstaff, Arizona The annual snowfall averages 100.3 inches (254.76 cm), placing Flagstaff among the snowiest incorporated cities in the United States.[28] Overall, the city features an average of 277 days without measurable precipitation each year. Despite snowstorms often being spread weeks apart, snow often covers the ground for weeks after major winter storms due to the low night temperatures refreezing the snowpack, even when daytime temperatures are above freezing. The maximum daily snow cover has been 83 inches (210.82 cm) on December 20, 1967, although the mean maximum for a full winter is only 20 inches (50.80 cm) and the lowest maximum only 6 inches (15.24 cm) in the dry winter of 1955–56. However, due to the infrequent and scattered nature of the snowstorms, persistent snow pack into spring is rare.[10] One notable exception occurred during the severe winter of 1915–16, when successive Pacific storms buried the city under over 70 inches (177.80 cm) of snow, and some residents were snowbound in their homes for several days.[29]
