Description

This event tracks the highest temperature reached in Boston on a specific future date, using an authoritative weather data provider. It helps participants assess climate conditions and temperature trends for that exact day. Outcomes are determined by comparing the recorded peak temperature against predefined ranges.

Kalshi

The event resolves based on the maximum temperature recorded at Boston’s official weather station (CLIBOS) on August 22, 2026, as reported by The Weather Company. Six distinct temperature ranges define possible outcomes: 68°F or below, 69–70°F, 71–72°F, 73–74°F, 75–76°F, and 77°F or above. The official temperature value comes exclusively from The Weather Company, regardless of other sources, and participants should be aware that preliminary readings may differ from the final reported value due to rounding or conversion adjustments. All markets depend solely on this single day’s peak temperature measurement.
