Trader consensus on Polymarket has locked in a 100% implied probability for Mexico City's highest temperature reaching 25°C or higher on April 29, driven by official forecasts from AccuWeather, Weather.com, and Mexico's Servicio Meteorológico Nacional projecting daytime highs of 31–34°C (88–93°F) under persistent high-pressure systems and clear skies. Recent observations at Benito Juárez International Airport confirm this heatwave pattern, with temperatures hovering at 30–32°C over the past week amid seasonal dry conditions and minimal cloud cover, far exceeding April climatological averages of ~26°C. While model consensus is robust, realistic challenges include unexpected afternoon thunderstorms or measurement discrepancies at official stations, though low-probability precipitation forecasts (under 5%) reinforce the near-certainty as the day progresses toward peak heating around 2–4 PM local time.
