Highest temperature in San Francisco on Sep 12, 2026?

Kalshi

The event resolves based on the maximum temperature recorded in San Francisco (CLISFO) on September 12, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a separate market that will resolve to "Yes" if the recorded high falls within its specified bounds. Markets cover temperatures from 66°F or below, through incremental bands up to 75°F or above. All markets share identical secondary rules emphasizing that while other weather sources may offer guidance, only The Weather Company's official reporting determines resolution. Participants must exercise caution with preliminary data due to potential rounding or conversion discrepancies. The exchange retains discretion to delay expiration if material errors are identified in initial publications, extending until either a corrected revision is issued or the original expiration date passes—whichever occurs first. Should no valid data remain available by the expiration deadline, all markets resolve to the last fair price established by Kalshi. Notably, a "Final" status on The Weather Company's platform serves only as a convenience indicator and does not immunize the data from post-publication corrections or exchange intervention.
