Description

This market predicts the highest temperature recorded in Houston on July 21, 2026. The outcome will be determined by the official National Weather Service Climatological Report (Daily) for that date, which provides the authoritative maximum temperature measurement for the location.

Kalshi

Resolution is based on the maximum temperature recorded at Houston-Hobby, TX on July 21, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed through the NWS regional climate portal. Temperature ranges are divided into six bands: 97°F or below, 98-99°F, 100-101°F, 102-103°F, 104-105°F, and 106°F or above. Each temperature range corresponds to a distinct market outcome. 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.
