This event tracks the highest temperature recorded in Boston on a specific date in 2026. Participants assess whether the temperature will fall within certain ranges based on official weather service data. The outcome depends solely on the official temperature report for that day.
The event resolves based on the maximum temperature recorded in Boston on August 11, 2026, as reported by the National Weather Service's Climatological Report (Daily) for Boston (Logan Airport), MA. Six separate outcome ranges are defined: 84° or below, 85-86°, 87-88°, 89-90°, 91-92°, and 93° or above. If the recorded temperature falls within any of these ranges on the specified date, the corresponding market resolves to Yes. All participants must refer exclusively to the official NWS data source provided; preliminary or third-party weather data should not be used for resolution. Traders should be aware that NWS data may include rounding or conversion nuances, and the latest available report for the date must be used for final determination.
