San Rafael's weather is influenced by its coastal location, with Pacific Ocean air bringing mild temperatures and high air pressure. This high pressure keeps clouds and rain away, making San Rafael sunny.
The surrounding hills and mountains block cold air from the north, keeping San Rafael warmer and more protected. This geography helps maintain moderate air pressure year-round.
In winter, cooler air from the Pacific brings lower pressure, resulting in more rainfall and cloudy skies. In summer, warm air from the land brings higher pressure, making it dry and sunny.
San Rafael has a Mediterranean climate, characterized by mild, wet winters and dry, warm summers. This climate type means air pressure changes seasonally, influencing weather patterns and precipitation.
