Description

This event tracks the highest temperature reached in San Francisco on a specific date in 2026. The outcome depends solely on official weather service data for that day, making it a straightforward test of real-world climate conditions.

Kalshi

The event resolves based on the maximum temperature recorded in San Francisco on July 25, 2026, as reported by the National Weather Service's Climatological Report (Daily) for San Francisco Airport. Six distinct temperature ranges are defined, each corresponding to a separate market outcome. If the recorded maximum temperature falls within any of these specified ranges, the associated market resolves to Yes; otherwise, it resolves to No. All participants must refer exclusively to the official NWS data source provided in the rules, as preliminary or third-party weather reports are not considered authoritative. Traders should be aware that NWS data may include rounding or conversion nuances, and the latest available report for the date must be used to determine the final outcome.
