This event tracks the highest temperature reached in San Francisco on a specific date in the future, using official government data. Participants assess temperature ranges based on recorded measurements from a designated weather station. The outcome depends solely on the official report released after the date in question.
All markets resolve based exclusively on the maximum temperature recorded at San Francisco Airport as reported in the National Weather Service's official Climatological Report (Daily) for July 23, 2026. Each market corresponds to a specific temperature range: 66°F or below, 67-68°F, 69-70°F, 71-72°F, 73-74°F, or 75°F and above. The market for the actual recorded temperature range will resolve to Yes, with all others resolving to No. Traders must reference the official NWS data linked in the rules, as preliminary or third-party reports are not binding. Due to potential rounding and conversion nuances in preliminary reports, caution is advised when interpreting early data. The final, authoritative temperature value comes from the NWS Daily Climate Report, which updates after the measurement period ends.
