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 August 13, 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 'Yes' outcome if the recorded maximum falls within that range: 63° or below, 64-65°, 66-67°, 68-69°, 70-71°, or above 71°. The official NWS data is the sole source for determination, and traders must use the latest version of the report for the date in question. Preliminary data from other services may differ due to rounding or conversion nuances, so caution is advised when interpreting such information. The resolution hinges entirely on the exact numerical value reported by the NWS, with each range representing a separate market outcome.
