Description

This event tracks the lowest temperature recorded in Houston on a specific date in the future, using official weather service data. The outcome depends entirely on the exact temperature reading reported by the National Weather Service for that day.

Kalshi

The event resolves based on the minimum temperature recorded in Houston on July 31, 2026, as officially reported by the National Weather Service's Climatological Report (Daily). Six distinct temperature ranges are defined, each corresponding to a different market outcome. If the recorded low falls within any of these specified ranges—from 71°F or below up to 80°F or above—the respective market resolves to Yes. All participants must rely exclusively on the NWS data source provided in the rules, as preliminary or third-party weather reports may differ due to rounding, conversion, or reporting timing variances. The official data source is updated after the event date, and traders should verify that they are using the latest version of the report when assessing outcomes. Caution is advised regarding interpretation of preliminary data, as official figures may change before final publication.
