This event tracks the highest temperature recorded in Washington DC on a specific date in 2026. The outcome depends on how hot it gets on that day according to official government data. It helps gauge extreme weather conditions for planning and analysis.
The event determines the resolution based on the maximum temperature recorded in Washington DC on July 31, 2026, as reported by the National Weather Service's Climatological Report (Daily). Six separate outcome ranges are defined: 87° or below, 88-89°, 90-91°, 92-93°, 94-95°, and 96° or above. If the recorded temperature falls within any of these ranges, the corresponding market resolves to Yes.
