Recent forecast model runs from agencies including Mexico's Servicio Meteorológico Nacional indicate peak temperatures in Mexico City tomorrow will likely reach 28–29°C, aligning with the market's leading implied probabilities near 72% combined. At 2,240 meters elevation, the city's highland location typically moderates extremes through cooler baseline air masses, though the ongoing summer rainy season brings variable cloud cover, humidity, and afternoon convection that can suppress or enhance daytime highs by 1–3°C. Recent observations show stable subtropical ridging with limited moisture advection, favoring modest warming relative to seasonal norms around 25–26°C. Traders appear to weigh ensemble consensus and historical analogs for late July, with resolution hinging on official maximum readings at the central observatory; any shift in overnight model guidance or unexpected clear-sky development could adjust these odds before close.
