Recent forecasts from Mexico’s Servicio Meteorológico Nacional project a maximum of 24–26 °C in Mexico City on August 30, driven by partly to mostly cloudy skies, moderate northeasterly winds, and a 40–60 % chance of afternoon showers or thunderstorms that can limit solar heating. At the city’s 2,240 m elevation, reduced insolation from convective clouds and evaporative cooling from rain are the key variables separating a 24 °C peak from 25 °C or 26 °C-plus outcomes. Ensemble guidance shows tight clustering around these values, with historical late-August highs averaging near 23 °C; traders therefore assign nearly equal weight to 24 °C and 25 °C while assigning lower probability to extremes outside the official envelope.
