Trader consensus on Polymarket overwhelmingly favors a high temperature of 27°C or higher in Mexico City today, with market-implied odds at 100%, driven by official forecasts from Mexico's Servicio Meteorológico Nacional (SMN) projecting maxima of 31–34°C amid an intensifying heat wave affecting the region. Clear skies, persistent high-pressure systems, and dry-season conditions—typical for late April, when average highs hover around 26–28°C—support rapid daytime heating at Benito Juárez International Airport's official station, the market's resolution source. Recent observations confirm the trend, with yesterday's highs exceeding 30°C. Realistic challenges include sudden cloud cover, gusty winds, or unforecasted showers shifting steering patterns, though model consensus shows low probability before evening cooldowns. Hourly SMN updates will refine this as the day unfolds.
