Current forecasts from NOAA-aligned models project San Francisco's minimum temperature on September 2 near 55–58°F, aligning closely with the 1991–2020 climatological average low of 56°F and driven by persistent onshore flow and a typical marine layer that moderates nocturnal cooling. This places the highest implied probabilities on the 56–59°F bins, while the 1% odds on 68°F+ reflect negligible warming potential under current synoptic patterns. Minor uncertainties in boundary-layer mixing, fog timing, and model spread around the 5–8 AM minimum window support balanced trader positioning across adjacent 2°F increments, with resolution hinging on official NWS observations at key stations. No anomalous heat or cold advection has emerged in recent days to shift consensus.
