This event tracks the lowest temperature reached in San Francisco on a specific date in the future. The outcome depends on how cold it gets during that day, with different temperature ranges determining the result. The official data source for temperature verification is The Weather Company.
The event resolves based on the minimum temperature recorded in San Francisco (CLISFO) on August 19, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a different market outcome. If the minimum temperature falls within a specific range, that associated market resolves to Yes. All markets are mutually exclusive and collectively exhaustive, ensuring one and only one will resolve as Yes depending on where the actual temperature falls. The Weather Company serves as the sole authoritative source for temperature data, with secondary sources like AccuWeather or Google Weather offered only as informal reference points. The precise numerical boundaries between ranges are critical in determining the correct resolution.
