**Market-implied odds favor 26°C (51%) as the most probable high for Mexico City on August 17, followed by 27°C (22.5%) and 25°C (20.5%).** This distribution reflects short-range forecast consensus from models and local monitoring, which place the daily maximum near 26–27°C (roughly 79–81°F) under partly cloudy skies with afternoon rain chances. Mexico City’s high elevation (~2,240 m) produces moderate highs even in summer; August’s rainy season typically features morning sun followed by convective showers that cap afternoon heating and prevent spikes above the seasonal average of ~24–25°C. Current guidance shows stable atmospheric conditions with limited moisture convergence or clear-sky heating that would push temperatures to 28°C or higher, keeping the upper tail of the distribution below 4% combined. Recent days have followed similar patterns, with observed maxima clustered around 24–26°C amid persistent cloud cover. Traders weigh these factors against the narrow window before resolution, when updated model runs or real-time observations from official stations could shift the modal outcome by 1°C.
