Description

This event tracks the lowest temperature recorded in San Francisco on July 18, 2026. The outcome will be determined by the official National Weather Service Climatological Report for that date, with resolution based on which temperature range the recorded minimum falls into.

Kalshi

Resolution is determined by the minimum temperature recorded at San Francisco Airport on July 18, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed through the NWS website by navigating to the Observed Weather tab and selecting San Francisco Airport with Daily Climate Report. Temperature ranges are: 49°F or below, 50-51°F, 52-53°F, 54-55°F, 56-57°F, and 58°F or above. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official NWS Climatological Report (Daily) takes precedence over other weather sources such as AccuWeather or Google Weather.
