Sonoma's air pressure is affected by its coastal mountain range, which blocks cold air from the Pacific Ocean. This creates a high-pressure system, making Sonoma's air pressure usually higher than in surrounding areas. In the summer, high pressure brings warm, dry weather. In the winter, low pressure brings cool, rainy weather. Sonoma has a Mediterranean climate, characterized by dry summers and wet winters, which affects air pressure patterns.
