This event forecasts the peak temperature in Boston on July 12, 2026. The outcome will be determined by the official National Weather Service daily climatological report for that date, which records the highest temperature reached at Boston Logan Airport.
Resolution is based on the maximum temperature recorded at Boston on July 12, 2026, according to the National Weather Service's Climatological Report (Daily) for Boston (Logan Airport), MA. The temperature is divided into six distinct ranges: 78°F or below, 79-80°F, 81-82°F, 83-84°F, 85-86°F, and 87°F or above. Each range corresponds to a separate market outcome that resolves to Yes if the recorded temperature falls within that bracket. Official data must be obtained from the NWS Climatological Report accessed through the specified URL and location selection, not from preliminary reports or alternative weather sources. Traders should be aware that preliminary NWS data may be subject to rounding and conversion nuances that could affect final resolution.
