Persistent marine layer and onshore flow from the Pacific suppressed daytime heating across San Francisco on August 17, 2026, anchoring the official high near the upper 60s to low 70s in line with National Weather Service climatology for the date. Official measurements confirmed a peak of 70–71°F, matching the narrow band favored by model consensus and historical averages around 67–70°F for mid-August. This strong scientific alignment produced the market’s near-certain 100% implied probability on that outcome. Scenarios that could have altered the result include an unexpected weakening of the marine layer allowing greater solar heating or a shift in steering patterns delivering warmer inland air, though neither materialized in the verified observations.
