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 solely on verified weather service reports.

Kalshi

All markets resolve based exclusively on the maximum temperature recorded in San Antonio, Texas, on July 31, 2026, as reported in the National Weather Service's official Climatological Report (Daily). Traders must access the data via the provided NWS URL, navigating to the 'Observed Weather' tab and selecting 'San Antonio' with the Daily Climate Report for the exact date. The most current version of the report should be used, acknowledging that update frequencies may vary between locations. While third-party weather services may offer preliminary or estimated values, they are not authoritative; only the NWS report serves as the binding reference. Traders should remain alert to any rounding, conversion, or reporting nuances in preliminary NWS data that could affect market resolution. Each market corresponds to a specific temperature range: below 98°F, 98–99°F, 100–101°F, 102–103°F, 104–105°F, or above 105°F. The temperature falling within any of these ranges triggers a 'Yes' resolution for that respective market.
