Trader consensus on Polymarket heavily favors 29°C (41.5%) and 30°C (30.5%) as São Paulo's highest temperature today, reflecting the latest forecasts from Brazil's National Institute of Meteorology (INMET) and Climatempo, which project peaks around 29°C amid a dominant subtropical high-pressure ridge suppressing cold fronts and promoting clear skies for strong diurnal heating. Morning observations at Congonhas Airport show temperatures rising from 19°C lows, consistent with above-average April norms of 25–27°C, boosted by urban heat island effects in the metropolitan area. Global models like GFS and ECMWF have converged on this outlook in recent runs, though isolated afternoon showers could slightly cap maxima; hourly station data through evening will refine resolution.
