San Bernardino's weather is influenced by its location near the San Gabriel Mountains, creating a rain shadow effect that blocks moisture from the Pacific Ocean.
The city's geography, with mountains to the north and east, traps warm air and creates high pressure, leading to clear skies and hot temperatures during the summer.
During winter, low-pressure systems from the Pacific bring cool, wet air, causing temperatures to drop and rain to fall, creating cloudy skies and cooler temperatures.
San Bernardino has a Mediterranean climate, characterized by dry summers and mild, wet winters, which affects air pressure, leading to hot summers and mild winters.
