Recent National Weather Service and model consensus points to a San Francisco overnight low in the upper 50s for August 21, 2026, driven by persistent marine-layer stratus and moderate west-northwest winds that limit radiational cooling. Typical August climatology yields an average low near 56 °F, with the current forecast range of 56–58 °F reflecting stable onshore flow and elevated dew points around 55 °F that suppress further temperature drops. Traders have priced the 58–59 °F bin highest because ensemble guidance shows little deviation from this narrow band absent an unexpected clearing or stronger gradient. Upcoming NWS updates and any shift in 500-mb heights will determine whether probabilities migrate toward the adjacent 54–55 °F or 60–61 °F outcomes.
