Persistent marine layer influence and onshore westerly winds from the Pacific are expected to cap highs in San Francisco on August 21, consistent with the market-implied clustering around 68–71°F. Recent NWS observations show mid-August daily maxima in the mid- to upper-60s amid frequent low stratus and fog, aligning with climatological normals near 69°F and the absence of offshore flow or ridging that would allow warmer interior air to reach the coast. Short-range model consensus favors mostly cloudy conditions with highs near 65–68°F, limiting upside risk above 72°F while keeping sub-66°F outcomes less probable under typical August solar heating. Traders appear to be weighting these stable cool-summer dynamics against minor forecast variability in marine layer depth.
