Description

This event tracks the highest temperature recorded in San Francisco on a specific date in the future, using official government data. The outcome depends entirely on the exact temperature measurement reported by the National Weather Service for that day. Participants assess weather conditions and historical trends to predict the likely temperature range.

Kalshi

The event resolves based on the maximum temperature recorded at San Francisco Airport on July 30, 2026, as officially reported by the National Weather Service's Climatological Report (Daily). Six distinct temperature ranges are defined, each corresponding to a separate market outcome. If the recorded temperature falls within a specific range, that market resolves to Yes, with all others resolving to No. The official data source is critical; preliminary or third-party weather reports are not considered authoritative. Traders must use the latest version of the NWS report for the date, acknowledging potential delays or variations in reporting timelines across different locations. Rounding and conversion nuances in preliminary NWS data should be carefully considered, as they may affect market resolution.
