Latest forecast ensembles from ECMWF, GFS, and Brazil's INMET/CPTEC models project São Paulo's March 28 high temperature in a tight 29-31°C range, aligning with trader consensus favoring 30°C (30.5% implied probability) over 29°C (25%) and 31°C (18.5%). This reflects a dominant subtropical high-pressure ridge over southeastern Brazil, promoting sunny skies, light winds, and daytime heating amplified by the urban heat island effect in the city. Past 24-hour model updates show minor spreads due to variable afternoon cloud development and sea breeze incursions, introducing uncertainty around the peak hour. Historical March highs average 28°C but often exceed 30°C in similar dry patterns; watch for INMET's evening briefing on potential convective tweaks.
