All markets resolve based solely on the maximum temperature recorded at Boston (Logan Airport), MA, as reported in the National Weather Service's official Climatological Report (Daily) for August 13, 2026. Each market corresponds to a specific temperature range: 80°F or below, 81-82°F, 83-84°F, 85-86°F, 87-88°F, or 89°F and above. The resolving authority will access the latest available data from the NWS Climate page, navigating to the 'Observed Weather' tab and selecting the Daily Climate Report for Boston (Logan Airport). Traders must recognize that preliminary data may contain rounding or conversion discrepancies, and only the final official report determines outcomes. External weather sources like AccuWeather or Google Weather are informational only and do not affect resolution.
