Description

This event tracks the highest temperature recorded in Boston on a specific date in the future, using official government data. Participants assess whether the temperature will fall within certain ranges based on verified meteorological reports.

Kalshi

The event resolves based on the maximum temperature recorded in Boston on August 7, 2026, as officially reported by the National Weather Service's Climatological Report (Daily) for Boston (Logan Airport), MA. Six distinct temperature ranges are defined, each corresponding to a separate market outcome. If the recorded temperature falls within a specific range, that market resolves to Yes; all others resolve to No. Data must be retrieved from the official NWS source after the date, using the most current report available. Traders should note that preliminary data from other services may differ due to rounding or conversion differences, and only the final NWS report determines the outcome.
