Trader consensus for a highest temperature of 24°C or higher in Mexico City on May 31 reflects established late-May climatology, where long-term records from the Servicio Meteorológico Nacional show average daily maxima of 25–28°C driven by subtropical high pressure, clear skies, and urban heat island amplification. Official observational networks routinely record values well above the 24°C threshold under these conditions, with minimal day-to-day variability this time of year. The near-100% implied probability leaves little room for anomalous cooling, which would require atypical cloud cover or frontal passage rarely seen in the region during peak spring warmth. Resolution hinges on final verified maximum readings from authorized stations.
