Description

This event tracks the highest temperature reached in Boston on a specific future date, using an authoritative weather data provider. It categorizes possible temperature outcomes into distinct ranges to determine the result.

Kalshi

The event resolves based on the maximum temperature recorded at Boston's official weather station (CLIBOS) on August 30, 2026, as reported by The Weather Company. Six temperature ranges are defined: 79°F or below, 80-81°F, 82-83°F, 84-85°F, 86-87°F, and 88°F or above. Each market corresponds to one of these ranges, and the market associated with the actual recorded temperature will resolve to 'Yes,' with all others resolving to 'No.' The Weather Company serves as the sole source for official temperature data, and users should exercise caution with preliminary readings due to potential rounding or conversion discrepancies.
