Trader consensus clusters tightly around 66–71°F for San Francisco’s official high on June 22 because short-range models and National Weather Service guidance show persistent onshore flow and a shallow marine layer capping daytime warming near the coast. This classic June pattern—stratus and fog burning off by midday—typically limits peaks to the mid-to-upper 60s at the KSFO station, with slight variations depending on the depth of the inversion and exact wind direction. Ensemble spreads remain modest, supporting the near-even probabilities across those three brackets, while warmer outcomes above 72°F require a stronger offshore component that current guidance does not indicate. Updated model runs tomorrow morning will refine the final range before the daily maximum is recorded.
