This market tracks the overnight low temperature in San Francisco on July 12, 2026. The outcome will be determined by the official National Weather Service daily climatological report for San Francisco Airport, which records the minimum temperature reached during that calendar day.
Resolution is based on the minimum temperature recorded at San Francisco Airport on July 12, 2026, as reported in the National Weather Service's Climatological Report (Daily), accessible via the NWS Metropolitan Transportation Office website. The reported temperature will be compared against six temperature bands: 51°F or below, 52–53°F, 54–55°F, 56–57°F, 58–59°F, and 60°F or above. Each band corresponds to a distinct market outcome. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official NWS Climatological Report (Daily) serves as the authoritative source, superseding other weather services.
