Trader consensus on Polymarket reflects the tight clustering of forecast ensembles from ECMWF and GFS models, projecting São Paulo's maximum temperature on May 14 at 25-26°C amid overcast skies and moderate southerly winds from a lingering cold front that cooled early May highs from near 27°C to the low 20s. Differentiating factors include model spread driven by uncertain timing of peak solar heating, urban heat island effects at monitoring stations like Congonhas Airport, and potential sea breeze intensification suppressing 27°C outcomes while cloudiness caps below 24°C. Historical mid-May averages hover at 23°C per INMET climatology, but current atmospheric stability favors the 25°C lead. Watch INMET's daily briefing and 12Z model updates on May 13 for shifts.
