The barometric pressure in Palo Alto is influenced by its proximity to the Pacific Ocean. This results in a consistent pressure pattern throughout the year. The pressure is highest during the summer months and lowest during the winter months. This fluctuation is due to the changing temperature and humidity levels.
Palo Alto is situated in the San Francisco Peninsula, surrounded by the Santa Cruz Mountains to the west and the San Francisco Bay to the east. The city's landscape is characterized by flat plains and gentle slopes. The mountains to the west block the flow of moist air from the Pacific, creating a rain shadow effect. This reduces the amount of rainfall in Palo Alto compared to nearby areas. The bay to the east also affects the local climate, moderating temperatures and contributing to the city's mild weather.
