Description

This event tracks the highest temperature reached in Boston on a specific date in the future. It categorizes possible temperature ranges to determine the outcome based on official weather data. The resolution depends solely on the recorded maximum temperature for that day.

Kalshi

The event resolves based on the maximum temperature recorded at Boston’s CLIBOS station on August 31, 2026, as reported by The Weather Company. Six distinct temperature ranges define the possible outcomes: 76°F or below, 77-78°F, 79-80°F, 81-82°F, 83-84°F, and 85°F or above. Each market corresponds to one of these ranges, and the market associated with the actual recorded temperature will resolve to Yes, while all others resolve to No. All temperature data used for resolution is the final reported value from The Weather Company, regardless of preliminary readings or data from other weather services. Users should note that preliminary data may vary due to rounding or conversion differences, and only the official report determines the outcome.
