Mexico City's high-elevation subtropical highland climate, at roughly 2,240 meters, typically limits mid-August daily maxima to near 24–26°C amid frequent afternoon convective clouds and showers during the rainy season. Current forecasts from agencies like the Servicio Meteorológico Nacional point to moderate insolation with scattered cloud cover and potential brief precipitation, keeping peaks in the narrow 25–26°C range favored by traders. Minor differences between these outcomes hinge on exact timing of cloud development, wind patterns, and urban heat retention versus evaporative cooling, introducing uncertainty that keeps probabilities closely split rather than decisive. Official station data will resolve the market.
