Description

This market tracks the lowest temperature recorded in San Francisco on July 20, 2026. The outcome will be determined by the official National Weather Service Climatological Report (Daily) for San Francisco Airport, which provides the authoritative minimum temperature measurement for that date.

Kalshi

Resolution is based on the minimum temperature recorded at San Francisco Airport on July 20, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed via the NWS Metropolitan Transportation Office website under the Observed Weather tab for San Francisco Airport. Temperature ranges are divided into six bands: 51°F or below, 52-53°F, 54-55°F, 56-57°F, 58-59°F, and 60°F or above. Each band corresponds to a distinct market outcome. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official NWS Climatological Report (Daily) serves as the definitive source, superseding other weather services.
