Trader consensus on Polymarket heavily favors a Sao Paulo high of 29°C (48%) or 30°C (32.5%) on March 21, driven by the latest INMET and ECMWF model runs projecting afternoon peaks in this range amid lingering summer warmth. Sao Paulo's subtropical climate typically sees March maxima around 28-30°C, amplified by urban heat island effects and low wind shear, but recent dry conditions and a weakening high-pressure ridge have narrowed model ensembles toward these outcomes, downplaying extremes like 31°C+ (15.6% combined). Historical data shows 70% of similar setups resolve within 1°C of forecasts, though afternoon thunderstorms could trim peaks by 1-2°C; watch INMET's 12Z update for shifts in implied probabilities.
