Will the maximum temperature in Monterrey exceed 24.5 °C on November 6, 2026?

Market context

This market resolves on the highest temperature recorded by station MMMY at General Mariano Escobedo International Airport over the full local day, according to the METAR observations published by NOAA.

Resolution criteria

• How it resolvesResolves YES if at least one observation from station MMMY (General Mariano Escobedo International Airport, Monterrey) for the local day of November 6, 2026 records a temperature strictly greater than 24.5 °C. Resolves NO if no observation that day does. Measurement window: the full local day, 00:00 to 23:59 on November 6, 2026, America/Monterrey time zone. Trading closes at 00:00 on November 6, 2026, Monterrey time (06:00:00 UTC), at the start of the measurement window. That close does not change the measurement window. Resolution source: METAR and SPECI reports for station MMMY published by NOAA at https://aviationweather.gov/api/data/metar?ids=MMMY&format=json&hours=48. The temperature in the body of the report is used. Groups in the RMK section are not used. Precision: station MMMY publishes temperature in whole degrees Celsius, so no observation can land exactly on 24.5 °C. A maximum of 24 °C or less resolves NO; 25 °C or more resolves YES. If data is missing: if NOAA publishes fewer than 20 observations for that local day, resolution waits until 23:59 on November 7, 2026, Monterrey time. If observations are still missing then, the market resolves NO. Corrections NOAA publishes after resolution do not change it.
