Vallejo's weather is affected by its location near the San Francisco Bay and the Pacific Ocean, which keeps air pressure relatively steady.
The city's geography, with surrounding hills and the bay, can trap warm air and create a slight increase in air pressure during summer.
In summer, high pressure dominates, bringing warm and dry weather with clear skies. In winter, low pressure takes over, leading to cooler and rainier conditions.
Vallejo has a Mediterranean climate, characterized by dry summers and wet winters, which means air pressure is usually highest in summer and lowest in winter.
