Although most of the state has a Mediterranean climate, due to the state’s large size the climate ranges from polar to subtropical. The cool California Current offshore often creates summer fog near the coast. Farther inland, there are colder winters and hotter summers. Northern parts of the state have more rain than the south. California’s mountain ranges also influence the climate: some of the rainiest parts of the state are west-facing mountain slopes.
