Trader consensus on Polymarket overwhelmingly favors 28°C or higher (98.9%) for Mexico City's highest temperature on May 1, backed by the latest Servicio Meteorológico Nacional (SMN) forecasts projecting maxima of 30–33°C amid a weakening but persistent mid-level anticyclonic circulation driving a late-April heat wave. Observational data from Tacubaya observatory confirm recent highs, including 32.4°C on April 29, well above May climatological averages of 25–26°C. Model consensus reflects clear skies turning partly cloudy, with low-probability showers (5–25 mm) and westerly winds up to 50 km/h gusts. Realistic challenges include heavier-than-expected precipitation suppressing daytime heating or an unforeseen cold air intrusion, though short-range guidance shows high confidence in sustained warmth ahead of official resolution via airport measurements.
