About Bay Area, California
Best Time to Visit
The best time to visit the Bay for weather is the early fall. The fog will subside for the season, and the sun is out on most days, offering just enough warmth without being hot.
This time of year is just after the busy tourist season as kids are back in school and people are preparing for their holiday breaks.
This means you will get great weather in September and October, but you won’t have to share the city’s attractions with many other tourists.
The other benefit is that prices of highly-rated hotels will be lower, and reservations at the Bay Area’s top restaurants will be easier to come by.
Bay Area Weather

The Bay Area weather is considered Mediterranean, but the region has unique characteristics that make for special conditions.
While San Francisco and the whole Bay Area face all four seasons each year, the overall temperature swings are held in check by the Pacific Ocean.
Another contributing factor is the wind that comes off the ocean and can make even a sunny summer day chilly.

This summer fog in the bay offers a reprieve from the heat that hits the rest of the state.
Fall
- Average coastal temperatures: High 69° Low 55° F
- Average inland temperatures: High 74° Low 54° F

Spring
- Average coastal temperatures: High 65° Low 51° F

Spring in the Bay area starts with a decent amount of rain, but it quickly tapers off, resulting in some gorgeous weather with highs in the mid-sixties to low-seventies.
