Trader consensus centers on 26–28°C for Mexico City’s highest temperature on August 2, reflecting seasonal norms during peak rainy-season conditions. High elevation near 2,240 m limits extremes, while frequent afternoon convection and cloud cover from the North American monsoon typically cap daytime maxima around the long-term August average of 23–24°C. Recent model guidance and historical observations from late July show highs reaching 26–27°C under partly cloudy skies with limited rain, supporting the elevated probabilities for 27°C. Minor variability arises from steering patterns and moisture availability that can either enhance or suppress daytime heating by a degree or two. No anomalous heatwave or clear-air subsidence is indicated in current forecasts, keeping the distribution tightly clustered and probabilities for outcomes above 29°C or below 25°C minimal.
