Recent forecasts from sources like AccuWeather and timeanddate converge on a Mexico City daily maximum near 24–25°C for July 10, with light showers and afternoon convective clouds typical of the North American monsoon season. This rainy-season pattern often caps peaks through reduced insolation and evaporative cooling, producing the tight 34.5%–30.5% spread between the 24°C and 25°C contracts. Slight model differences in cloud timing and precipitation onset explain why 23°C trails at 16% while higher outcomes remain below 9%. Historical July climatology centers on 23–24°C averages, but day-to-day variability from highland elevation and thunderstorm development keeps the market closely balanced ahead of final observational data.
