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 10, 2026, as reported by the National Weather Service's Climatological Report (Daily). Each market corresponds to a specific temperature range: 85° or below, 86-87°, 88-89°, 90-91°, 92-93°, or 94° 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 and location. Traders must use the latest published report, noting that preliminary data may undergo revisions due to rounding or conversion processes. While third-party weather services may offer estimates, only NWS-reported values determine resolution. Care should be taken to account for potential discrepancies in reporting timelines across different cities.
