Description

This event tracks the highest temperature reached in San Antonio on a specific date in the future, using official government data. The outcome depends on how hot it gets, with different ranges determining resolution. All outcomes are based on verified meteorological reports.

Kalshi

All markets resolve based solely on the maximum temperature recorded on August 1, 2026, in San Antonio as reported by the National Weather Service's official Climatological Report (Daily). The temperature must be verified from the specific NWS climate data portal, not third-party services. Each market corresponds to a distinct temperature range: below 97°F, 97-98°F, 99-100°F, 101-102°F, 103-104°F, or above 104°F. Traders should note that NWS data may undergo revisions, and only the latest official report for that date will be used for resolution. Preliminary readings or unofficial sources cannot override the authoritative NWS record.
