This event tracks the lowest temperature recorded in San Francisco on July 19, 2026. The outcome will be determined by the official National Weather Service daily climatological report for San Francisco Airport, which measures the minimum temperature that occurs during the calendar day.

Kalshi

Resolution is based on the minimum temperature recorded at San Francisco Airport on July 19, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed through the NWS Western Region Climate portal by selecting San Francisco Airport with the Daily Climate Report option. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official report should be used for resolution. While secondary sources like AccuWeather or Google Weather may provide guidance, only the NWS Climatological Report (Daily) serves as the authoritative source for determining the outcome.
