Golden Gate Bridge · San Francisco, CA. Data: exact sun position; climate normals from historical weather; live forecast on the interactive view.
There is no shade on the Golden Gate Bridge. The walkway runs the full length of the span with nothing overhead but the towers and cables, so anyone crossing on foot or by bike is in the open the entire way. That sounds worse than it is, because San Francisco's climate does you a favor: July afternoon highs hover around 71°F, and the wind and fog off the Pacific are usually the bigger factors than the sun. Still, the crossing is a long, unbroken stretch of exposure, and it helps to know what you're walking into.
Bridges give you no shade, and the Golden Gate is no exception, the pedestrian path is exposed from tower to tower with no overhang or shelter along the way. On a July afternoon the sun sits about 62 degrees high at 3 PM on a west-southwest bearing near 241 degrees, coming in off the ocean side of the span. The one nuance is the towers: as you pass beneath them, each throws a broad shadow across the deck, a brief moment of shade in an otherwise open walk. Beyond that, plan on full sun whenever the fog isn't in. The good news is that the exposure is a comfort issue here, not a heat-danger one, at 71°F the sun on the bridge is pleasant more often than punishing.
The Golden Gate is famous for its fog, and on many summer days the marine layer swallows the bridge entirely, wiping out the sun and dropping the temperature fast. When the fog is in, the concern flips from glare to cold and wind, the span funnels a stiff, chilly breeze most afternoons.
With sunrise around 6:00 AM and sunset near 8:31 PM, you have a long window, and no month here is truly hot, the warmest afternoons, in late summer and early fall, still top out near 71°F. That means the choice of when to walk the Golden Gate Bridge is driven by fog and wind, not heat. Late morning and early afternoon on a clear day give you the best light and the warmest air; if the marine layer is thick, expect a grey, blustery crossing whatever the hour.
