Persistent upper-level ridging and weaker-than-normal onshore flow have sustained above-normal temperatures across the San Francisco Bay Area, driving trader sentiment toward elevated overnight lows for October 6. National Weather Service forecasts indicate sunny conditions with daytime highs in the low-to-mid 70s and minimum temperatures holding in the upper 50s to low 60s—roughly 5–8°F above the historical average low near 55°F—due to limited marine layer intrusion and continued heat-risk conditions. Recent model runs show only modest cooling Tuesday night, keeping the daily minimum unlikely to fall to typical October levels. This setup explains the market-implied clustering around 56–71°F ranges alongside elevated odds for 72°F or higher, as traders weigh the strength of the ridge against any last-minute forecast shifts before resolution.
