Recent short-term forecasts for Mexico City point to a daily maximum near 26–27°C on August 4, aligning with the market’s leading 27°C outcome at 44% implied probability. At 2,240 m elevation in the Valley of Mexico, the city experiences moderated subtropical summer conditions where afternoon convection and scattered showers often cap temperatures below peak values seen at lower elevations. Model consensus from sources such as AccuWeather and timeanddate shows highs of roughly 26–27°C under partly cloudy skies with late-day moisture, consistent with August climatology of 24–26°C average highs and rare excursions above 28°C. No significant heat-wave signals or model outliers have emerged in the past 48 hours, keeping 28°C and higher probabilities subdued at 21% and below. Updated National Meteorological Service guidance and next model runs will refine the exact maximum before resolution.
