Description

This event tracks the highest temperature recorded in Boston on a specific date in 2026. Participants assess whether conditions will reach certain temperature thresholds based on official weather service data. The outcome depends solely on the maximum temperature measured at a designated location on that day.

Kalshi

All markets resolve based on the maximum temperature recorded at Boston (Logan Airport), MA on August 3, 2026, as reported by the National Weather Service's Climatological Report (Daily). Each market corresponds to a specific temperature range: 76°F or below, 77-78°F, 79-80°F, 81-82°F, 83-84°F, or 85°F and above. The official data source is accessible via the NWS Climate website under the 'Observed Weather' tab, using the Daily Climate Report for the specified date. Traders must use the latest available report and recognize that preliminary data may contain rounding or conversion nuances, requiring careful interpretation. All markets are exclusive, meaning the temperature will fall into exactly one category, resolving the corresponding market to 'Yes' and all others to 'No'.
