Weather

A mild climate close to everything.

Mild weather and steady temperatures make Pleasant Hill a destination to enjoy in every season. Thanks to the nearby Pacific Ocean, our city benefits from a moderate maritime climate, meaning temperatures stay steady, typically ranging between 40°F and 86°F throughout the year. Summers bring warm, dry days with fog in the morning and evening, while Spring and Fall are cool and comfortable with little rain. Winters are mild, with most rainfall occurring between December and March.

Whether strolling through scenic parks, visiting local vineyards, or dining on outdoor patios, packing layers will help you stay comfortable. Lightweight clothing works well during sunny afternoons, while a warm sweater or light jacket will keep you warm during cooler evenings.
