Description

This event tracks the lowest temperature recorded in San Francisco on a specific date, using official government data. The outcome depends entirely on the exact temperature measurement reported by the National Weather Service for that day. Participants assess weather forecasts and historical trends to predict the result.

Kalshi

All markets resolve based solely on the official minimum temperature recorded at San Francisco Airport on August 7, 2026, as reported in the National Weather Service's Climatological Report (Daily). The report must be accessed via the provided URL, navigating to the 'Observed Weather' tab and selecting the Daily Climate Report for San Francisco Airport. The latest available version of the data should be used, acknowledging that update frequencies may vary between locations. While third-party weather services may offer guidance, they are not authoritative—only the NWS report determines resolution. Traders must remain cautious with preliminary NWS data, as it may undergo revisions due to rounding, conversion nuances, or other measurement adjustments before the final report is published. Each market corresponds to a specific temperature range or threshold: below 53°F, 53–54°F, 55–56°F, 57–58°F, 59–60°F, or above 60°F. The market resolving to 'Yes' is the one whose defined range or threshold matches the officially reported minimum temperature.
