Description

This event tracks the highest temperature reached in San Francisco on a specific date in the future. The outcome depends on official weather data from a designated source, reflecting climate conditions for that day.

Kalshi

The event resolves based on the maximum temperature recorded in San Francisco on October 17, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range, with one market covering temperatures of 77°F or below and another for temperatures above 85°F, while the remaining markets cover incremental ranges between these values. All markets share common secondary rules regarding data verification and error handling. If preliminary data appears erroneous, the exchange may delay resolution until a corrected value is published or until the expiration date. In cases where data remains unavailable by the expiration date, markets will resolve to the last fair price determined by the exchange. The 'Final' status on The Weather Company's platform is informational and does not guarantee data accuracy or exempt markets from potential revisions.
