With chilly winters, hot, dry summers, and moderate rainfall, Modesto has a climate that mixes elements of a cold semi-arid and hot-summer Mediterranean climate. The majority of the year's precipitation, about 13.2 inches on average, falls in the winter. Periodic droughts and heavier rainfall brought on by El Nio episodes can be experienced in Modesto. Streets occasionally flood during winter storms since the city doesn't have a complete storm drain system. Temperatures normally range from 30°F to 103°F, and snowfall is uncommon. While highs in July hover around 95°F, January's daily average temperature is 56°F and at night it is 34°F. The "delta breeze," which brings relief from the heat in the nights, makes Modesto slightly cooler than other Central Valley locations.
