This event tracks the lowest temperature that will occur in San Francisco on a specific date in the future. The outcome depends entirely on official weather data from a designated source, making it a straightforward test of actual climatic conditions on that day.
All markets resolve based solely on the minimum temperature recorded at San Francisco (CLISFO) on September 21, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 52°F or below, 53°F to 54°F, 55°F to 56°F, 57°F to 58°F, 59°F to 60°F, or above 60°F. The Exchange retains discretion to delay resolution if it identifies material errors in the initial data publication, allowing time for corrected data or proceeding to the Expiration Date. If no valid data exists by the deadline, markets resolve to the last fair price determined by Kalshi. Preliminary readings may differ from final values due to rounding or conversion, and the "Final" status on The Weather Company’s platform does not guarantee error-free data.
