Current official forecasts from Mexico's Servicio Meteorológico Nacional project a maximum of 26-28°C in Mexico City on May 16, aligning with the market's near-certainty for 24°C or higher. This reflects recent observed highs of 26-29°C, combined with May climatology showing average peaks near 26°C at the city's 2,240-meter elevation, where persistent high-pressure ridging and strong diurnal heating from intense solar insolation reliably drive afternoon warmth. Ensemble models from GFS and ECMWF indicate minimal disruption from early rainy-season showers. A realistic scenario that could challenge the outcome involves unexpected prolonged cloud cover from chubascos limiting surface heating, though current guidance views this as improbable ahead of final hourly observations tomorrow.
