Trader consensus on Polymarket overwhelmingly favors 28°C or higher as Mexico City's peak temperature today at Benito Juárez International Airport, with 99.7% implied probability reflecting strong alignment across forecast models from the Servicio Meteorológico Nacional (SMN) and international sources like ECMWF and GFS. Clear skies under a persistent high-pressure ridge, combined with dry season conditions before rainy season onset, are driving expectations of highs reaching 29-31°C, consistent with recent observations of 30°C+ in late April and historical May averages around 26-27°C that have trended warmer amid climate variability. Model runs updated in the last 24 hours show no divergence, with minimal cloud cover projected. Realistic challenges include an unexpected afternoon shower or northerly wind shift introducing cooler air, though current upper-air patterns make this unlikely; hourly airport observations will provide final confirmation by evening.
