Recent forecasts from multiple models indicate a daily maximum of 23–25°C in Mexico City on August 28, driven by persistent cloud cover, scattered afternoon thunderstorms, and moderate northeasterly winds typical of the late-summer rainy season at 2,240 m elevation. These conditions limit surface heating and align with observed highs of 21–24°C over the prior 48 hours amid elevated humidity and precipitation. Trader consensus, reflected in the 52.5% implied probability for 25°C, centers on this range because ensemble guidance shows limited potential for clear skies or stronger insolation that would push readings to 26°C or higher, while cooler outcomes remain less likely absent stronger frontal influences. Updated model runs and official briefings over the next 24 hours will refine the exact peak.
