The event tracks the peak daytime warmth in San Diego on a specific summer day in 2026. It examines whether the city experiences unusually hot conditions or remains within a moderate temperature band during that August afternoon.
This event determines the outcome based solely on the maximum temperature recorded at San Diego's CLISAN weather station on August 19, 2026, as reported by The Weather Company. Six distinct temperature ranges are evaluated: below 79°F, 79-80°F, 81-82°F, 83-84°F, 85-86°F, and above 86°F. The market resolves to Yes for the specific range that matches the actual recorded high temperature. All outcomes use identical verification methodology, with The Weather Company's report serving as the exclusive official source regardless of discrepancies with other weather services.
