Recent forecasts from Mexico's Servicio Meteorológico Nacional and international models indicate a daytime high near 25–27°C for Mexico City on October 13, driven by partly cloudy skies, light easterly winds, and residual moisture that limits full solar heating at the city's 2,240-meter elevation. Trader emphasis on 25°C reflects model consensus around this value amid scattered showers and urban heat-island effects, while the sizable 26°C-or-higher share accounts for potential brief clearing that could push peaks higher. Lower outcomes remain discounted because climatological October averages near 23°C and current observations show minimal cooling from persistent cloud cover or stronger precipitation. Updated model runs and official afternoon readings will determine the precise maximum used for market resolution.
