This event tracks the lowest nighttime temperature in Phoenix on a specific date in the future, using official government data. The outcome depends entirely on how cold it gets during that night, with different temperature ranges determining the result.
All markets resolve based solely on the official minimum temperature recording for Phoenix, Arizona on August 3, 2026, as reported in the National Weather Service's Climatological Report (Daily). The National Weather Service's data is the definitive source, and traders must access the report via the provided URL, navigating to the "Observed Weather" tab and selecting "Phoenix, AZ" with the Daily Climate Report option. The latest available version of the data for the specified date must be used, acknowledging that reporting frequencies may vary across different locations. While preliminary data from services like AccuWeather or Google Weather may offer guidance, they are not authoritative; only the NWS report determines the market outcome. Traders should remain cautious when interpreting preliminary NWS data due to potential rounding and conversion nuances in reporting and measurement methodologies. The market resolves to Yes for the temperature range specified in each individual rule if the recorded minimum temperature falls within that range; otherwise, it resolves to No.
