Description

This event tracks the highest temperature recorded in Houston on a specific date, using official government data as the sole source for verification. Participants assess the likelihood of different temperature ranges based on historical trends and forecasts.

Kalshi

All markets resolve based solely on the maximum temperature recorded at Houston-Hobby Airport on July 31, 2026, as reported in the National Weather Service's official Climatological Report (Daily). The outcome is determined by which temperature range—defined by specific degree thresholds—the recorded maximum falls into. Each market corresponds to a distinct range: below 94°F, 94–95°F, 96–97°F, 98–99°F, 100–101°F, or above 101°F. Traders must rely exclusively on the NWS report for resolution, as preliminary or third-party data sources are not considered authoritative. It is important to note that NWS data may undergo revisions, and participants should use the latest published report for the date in question. Rounding and conversion methodologies inherent in NWS reporting may affect the final outcome, so caution is advised when interpreting early or unofficial data.
