Description

This event tracks the highest temperature recorded in San Francisco on a specific date, using official government data as the sole source for verification. Participants assess temperature ranges based on historical patterns and seasonal forecasts to determine outcomes.

Kalshi

All markets resolve based solely on the maximum temperature recorded at San Francisco Airport on July 28, 2026, as reported in the National Weather Service's official Climatological Report (Daily). The report must be accessed via the provided URL, navigating to the 'Observed Weather' tab and selecting the Daily Climate Report for San Francisco Airport. The latest available version of the data should be used, with awareness that reporting frequencies may vary between locations. While third-party weather services may offer preliminary or estimated data, they are not authoritative for resolution purposes. Traders must recognize that NWS data may include rounding or conversion nuances in preliminary reports, necessitating careful interpretation until final official figures are confirmed.
