Key takeaway Weekend Weather Guide The Cool Down A deeply entrenched storm trough has pulled in a strong marine layer, dropping temperatures up close to 10 seasonal normal averages.
Why this matters in The San Francisco
The return of the marine layer and cool temperatures will be a welcome relief for many San Francisco residents, particularly those who have been dealing with the recent smoke from nearby wildfires. The cooler conditions will not only provide a break from the heat, but also help to improve air quality, making it easier for people to breathe. As the fog rolls in, residents in the East Bay and North Bay valleys can expect a noticeable drop in temperature, making outdoor activities more enjoyable. The beautiful sunny skies expected on Saturday afternoon will also be a great opportunity for people to get out and enjoy the city's many parks and outdoor spaces. With the possibility of dry lightning or thunderstorms on the horizon, residents should stay tuned to local weather forecasts to plan their outdoor activities accordingly.
