Description

This market tracks the highest temperature recorded in San Francisco on July 19, 2026. The outcome is determined by the maximum temperature reading from the National Weather Service's official daily climatological report for San Francisco Airport, which serves as the authoritative source for weather data in the region.

Kalshi

Resolution is based on the maximum 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 via the NWS website by navigating to the Observed Weather tab and selecting San Francisco Airport with Daily Climate Report. The temperature is divided into six ranges: 66°F or below, 67-68°F, 69-70°F, 71-72°F, 73-74°F, and 75°F or above. Each range corresponds to a separate outcome. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official NWS Climatological Report (Daily) value takes precedence over other weather sources such as AccuWeather or Google Weather.
