Persistent high pressure over the western U.S. has sustained above-average warmth across the San Francisco Bay Area into early October 2026, with official NWS and model guidance showing clear skies and light winds limiting overnight radiative cooling for October 6. Forecast lows cluster in the low 60s °F, well above the 1991–2020 climatological average minimum of 55.2 °F for the date. This setup elevates implied probabilities for the warmest bins, particularly 72 °F or higher, while keeping colder outcomes like 53 °F or below near zero. Traders are weighting the current airmass and steering patterns more heavily than typical seasonal cooling, with the next 48-hour model updates likely to refine land-breeze and marine-layer influences before resolution.
