Trader consensus on Polymarket reflects near-certainty for Mexico City's highest temperature reaching 26°C or higher on April 30, driven by the Servicio Meteorológico Nacional's (SMN) latest forecast predicting a maximum of 31–33°C amid a persistent heatwave affecting central Mexico since April 25. This positioning stems from an anticyclonic circulation at mid-levels maintaining clear skies, light winds, and above-normal temperatures—observational data from Benito Juárez International Airport show recent daily highs near 30–32°C, exceeding April's climatological average of 26°C. Model ensembles from SMN and international sources align on minimal precipitation risk (under 10%), supporting sustained daytime heating. Realistic challenges include an unforeseen influx of cooler northerly air or isolated afternoon showers, though probabilities remain low per current guidance.
