Forecasts for Mexico City on August 13 center on a daily maximum of 25–26°C, reflecting typical rainy-season conditions at the city's 2,240-meter elevation. Official guidance from sources such as the Servicio Meteorológico Nacional and international models shows partly cloudy skies with afternoon showers possible, which can suppress peak temperatures through evaporative cooling and increased cloud cover. Diurnal temperature ranges remain wide due to altitude and urban heat-island effects, while steering patterns and moisture from the monsoon keep conditions near seasonal norms of roughly 24°C. Minor differences among model runs—particularly the exact timing and coverage of convection—create the tight market split between the 25°C and 26°C outcomes, with updates from morning observations and afternoon radar likely to refine the final recorded high.
