Description

This event tracks the highest temperature recorded in Houston on a specific date in the future, using official government data. Participants assess climate conditions and historical trends to predict temperature ranges, with outcomes determined by verified meteorological reports.

Kalshi

The event resolves based on the maximum temperature recorded in Houston on July 28, 2026, as officially reported by the National Weather Service's Climatological Report (Daily) for Houston-Hobby, TX. 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, with all others resolving to No. The official data source must be accessed via the provided NWS URL, and traders should use the latest available report for the date. All outcomes rely exclusively on NWS data—no alternative sources or preliminary readings are valid for resolution. Traders must account for potential rounding, conversion nuances, and reporting delays inherent in meteorological data.
