Description

This event tracks the lowest temperature recorded in San Francisco on a specific future date, using official government data sources. The outcome depends entirely on the exact numerical reading from the National Weather Service's official daily climate report for that location and date.

Kalshi

All markets resolve based solely on the official minimum temperature recorded at San Francisco Airport as reported in the National Weather Service's Climatological Report (Daily) for August 9, 2026. The report must be accessed via the provided NWS URL after the date passes, using the latest available version. Each market corresponds to a specific temperature range: below 54°F, 54-55°F, 56-57°F, 58-59°F, 60-61°F, or above 61°F. Traders should note that while third-party weather services may show similar data, only the NWS report serves as the binding authority. Preliminary NWS data may contain rounding or conversion discrepancies, so final resolution waits for the official report. All outcomes are mutually exclusive and collectively exhaustive within these defined ranges.
