Forecast models for Mexico City on August 6 point to a daytime high near 25–26°C, driven by the peak of the rainy season when persistent cloud cover and scattered showers suppress solar heating at the city’s 2,240-meter elevation. Official guidance from agencies such as the Servicio Meteorológico Nacional highlights moderate instability with light northerly winds and afternoon convection that caps temperatures below historical August maxima. The narrow spread between the 25°C and 26°C outcomes reflects minor differences in model timing of precipitation and boundary-layer moisture, both of which can shift the peak by 1°C. Historical climatology shows typical August highs of 23–24°C, so current conditions sit slightly above average yet remain far from extreme heat thresholds. Updated model runs and real-time surface observations through the afternoon will determine the final recorded maximum used for market resolution.
