Description

This event tracks the lowest temperature recorded in San Francisco on a specific date, using official government data as the sole source for verification. Participants assess whether conditions will fall within particular temperature ranges based on authoritative meteorological reports.

Kalshi

All markets resolve based solely on the official minimum temperature recorded at San Francisco Airport on July 30, 2026, as reported in the National Weather Service's Climatological Report (Daily). The outcome depends on which temperature range the official reading falls into: below 52°F, between 52-53°F, 54-55°F, 56-57°F, 58-59°F, or above 59°F. Traders must rely exclusively on the NWS data linked in the rules, as preliminary or third-party weather sources are not considered official for resolution purposes. It is important to note that NWS reports may undergo revisions, and participants should use the latest available data for verification after the event date. Rounding and conversion methodologies inherent in NWS reporting may impact market outcomes, so caution is advised when interpreting early or provisional data.
