Description

This market tracks the highest temperature recorded in Houston on July 18, 2026. The outcome will be determined by the official National Weather Service Climatological Report (Daily) for Houston-Hobby Airport, which provides the authoritative temperature measurement for the region.

Kalshi

Resolution is based on the maximum temperature recorded at Houston on July 18, 2026, according to the National Weather Service's Climatological Report (Daily) for Houston-Hobby, TX. The official data source is accessed via the NWS website under the "Observed Weather" tab. Temperature ranges are divided into six outcomes: 92°F or below, 93-94°F, 95-96°F, 97-98°F, 99-100°F, and 101°F or above. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official report should be used for resolution rather than preliminary estimates or third-party weather services.
