Trader sentiment for Sao Paulo's highest temperature on March 22 clusters tightly around 29–32°C, with 31°C leading at 28.5%, driven by INMET and international model ensembles forecasting a peak near 30–31°C amid lingering summer warmth from El Niño influences. Recent GFS and ECMWF updates show slight divergence—GFS leaning hotter at 31–32°C due to clearer skies and urban heat island amplification in the city center, while ECMWF tempers to 29–30°C with potential afternoon sea breeze moderation. Historical March maxima average 29°C, but this year's above-baseline soil moisture and low wind shear favor the upper end; traders eye tomorrow's 12Z model runs for resolution-defining clarity on convective activity thresholds.
