Long Beach

Long Beach has a climate that can either be described as a hot semi-arid climate or a hot-summer Mediterranean climate. In general, the city features hot summers and mild to warm winters with occasional rainfall. Days in Long Beach are mostly sunny, as in Southern California in general. Temperatures recorded at the weather station at the Long Beach Airport, 4.0 miles (6.4 km) inland from the ocean, range more greatly than those along the immediate coast. During the summer months, low clouds and fog occur frequently, developing overnight and blanketing the area on many mornings. This fog usually clears by the afternoon, and a westerly sea breeze often develops, keeping temperatures mild. Heat and high humidity can sometimes coincide in summer, which may cause discomfort due to the heat index.

Long Beach's location directly east of the Palos Verdes Peninsula, paired with its south facing coastline, results in the city sometimes experiencing different weather patterns than the Los Angeles metropolitan area coastal communities to the northwest and southeast of Long Beach, which largely have west facing coastlines. The 1200 ft Palos Verdes hills block west to east airflow and a significant amount of the coastal moisture that marks other coastal cities, such as Manhattan Beach, Santa Monica, and Newport Beach.
