Trader consensus on the 70-71°F bin reflects the official high temperature recorded on August 13, 2026, at the resolution station, which aligned precisely with that narrow range after a period of marine layer moderation. National Weather Service observations and nearby station data confirmed peak readings near 70°F amid typical August coastal patterns, where onshore flow and fog limited daytime warming below seasonal norms around 71-74°F. This outcome matches climatological baselines for San Francisco in mid-August, with minimal model deviation from prior forecasts. Only an anomalous heat spike from offshore flow or measurement revision at the exact station could have shifted resolution, though no such data emerged.
