Description

This event tracks the lowest temperature recorded in San Francisco on a specific future date, using official government data sources. The outcome depends entirely on the exact numerical reading from the National Weather Service's official daily climate report for that day.

Kalshi

All markets resolve based solely on the official minimum temperature recorded at San Francisco Airport as reported in the National Weather Service's Climatological Report (Daily) for August 10, 2026. Each market corresponds to a specific temperature range: 52°F or below, 53-54°F, 55-56°F, 57-58°F, 59-60°F, or above 60°F. The NWS report is the definitive source, and traders must use the latest published data for the date. While third-party weather services may provide similar data, they are not authoritative for resolution purposes. Traders should be aware that preliminary NWS data might contain rounding or conversion nuances, and only the final official report determines the outcome. All markets are mutually exclusive and collectively exhaustive within the defined temperature bands.
