Official National Weather Service observations for September 7, 2026, recorded a daily maximum of 80–81°F at the primary San Francisco station used for market resolution, aligning precisely with trader consensus at 100% implied probability. This outcome reflects verified surface measurements under clear skies and light onshore flow typical of early September, falling several degrees above the 1991–2020 climatological normal high near 70°F yet well below historical September extremes exceeding 90°F. With data now finalized after the event window closed, revisions are improbable absent rare instrumentation corrections. Only an unforeseen station-specific anomaly or definitional dispute could alter resolution, though current evidence supports near-certain settlement in the 80–81°F bin.
