Climate
Fresno has relatively mild winters and very hot summers. December low temperatures average 37.0 °F (2.8 °C) with July high temperatures averaging 98.6 °F (35.9 °C), though summer temperatures regularly soar to highs of 105 °F (40 °C) or more. Summers provide considerable sunshine, with July peaking at 97 percent of the total possible sunlight hours; conversely, January is the lowest with only 46 percent of the daylight time in sunlight. Average annual precipitation is 11.23 in (28.52 cm); rainfall is concentrated in the winter and spring seasons, with the summers typically being very dry. Most of the wind rose direction occurrences derive from the northwest, as winds are driven downward along the axis of the California Central Valley; in December, January and February there is an increased presence of southeastern wind directions in the wind rose statistics. Fresno meteorology was selected in a national U.S. Environmental Protection Agency study for analysis of equilibrium temperature for use of ten-year meteorological data to represent a warm, dry western United States locale.
