**Recent National Weather Service and model guidance points to mostly sunny conditions on September 7 with light variable winds shifting northwest, supporting a daily high in the upper 70s.** San Francisco’s marine layer and typical onshore flow from the Pacific often cap temperatures, but clearing skies and reduced cloud cover on the 6th have set the stage for modest warming above the long-term September 7 average of roughly 70°F. Forecasts from multiple sources cluster between the mid-70s and low-80s, with the tightest consensus around 75–79°F depending on the exact timing of any remaining marine influence or afternoon sea breeze. This scientific setup—clearer skies allowing greater solar heating while coastal moderation prevents extremes—explains why market-implied odds concentrate on the 78–79°F and 80–81°F bins as the most probable outcomes. Traders appear to weigh the latest model runs and historical analogs showing occasional late-summer warm spells in the upper 70s when high pressure builds offshore. Key upcoming data points include the next NWS forecast update and any revised model guidance on wind patterns or marine layer depth, which could shift probabilities if onshore flow strengthens or weakens.
