Fogs in San Francisco 2025

A peculiar weather phenomenon occurs in San Francisco Bay Area during hot summer months. When hot air from the land is substituted by colder and heavier ocean air, the flow from the high to the low-pressure zone creates a thick fog, which rushes through the Golden Gate Bridge and covers the Bay. Walking across the bridge, when the tide of fog comes in, is an activity for adventurous.

The foggy season lasts from June to early September. Mornings and evenings provide the most interesting photo opportunities. For the best views, go atop of San Francisco’s Hills and watch the mist beneath covering the city. Take some warm clothes, a picnic busket and a cup of hot chocolate to enjoy these outstanding sceneries.
