Description

The event tracks the lowest temperature in San Francisco on August 18, 2026, using data from The Weather Company. Outcomes depend on whether the minimum temperature falls into specific ranges, providing a clear benchmark for weather conditions that day.

Kalshi

The market resolves based on the minimum temperature recorded at San Francisco (CLISFO) on August 18, 2026, as reported by The Weather Company. Six separate temperature ranges are defined, each corresponding to a different market outcome. If the minimum temperature is 51°F or below, the first market resolves to Yes. If it is between 52°F and 53°F, the second market resolves to Yes, and this pattern continues for subsequent ranges up to 58°F to 59°F. For temperatures of 60°F or above, the final market resolves to Yes. The Weather Company’s data is the sole authority for determining the outcome, and all participants must rely on this source for accuracy.
