Description

This event tracks the highest temperature recorded in San Francisco on a specific date in 2026. The outcome depends solely on official weather service data, ensuring consistency and reliability for all participants.

Kalshi

The event resolves based on the maximum temperature recorded in San Francisco on August 10, 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. The ranges are: 71°F or below, 72-73°F, 74-75°F, 76-77°F, 78-79°F, and 80°F or above. All participants must refer to the official NWS data source provided, as preliminary or third-party weather reports are not considered valid for resolution. Traders should be aware that NWS data may undergo revisions, and the latest published report for the specified date will be used to determine the outcome. Rounding and conversion nuances in the reporting process are acknowledged, and caution is advised when interpreting early or unofficial data.
