Trader consensus on Polymarket reflects tight forecast clustering around 27–28°C for São Paulo's highest temperature on April 5, driven by recent ECMWF and GFS model runs showing daily highs of 80–82°F (27–28°C) under humid conditions with partial sun and afternoon thunderstorms. AccuWeather projects 82°F with variable cloudiness and isolated storms, while timeanddate.com indicates 80°F, highlighting model divergence on cloud timing—earlier showers could cap peaks at 27°C by limiting insolation, versus clearer skies pushing to 28°C. Above-normal early April heat persists from a subtropical high-pressure ridge and ENSO-neutral transition favoring warmth in Brazil's center-south, exceeding the 25°C historical average. INMET notes elevated temperatures regionally; watch daily updates for refined ensemble probabilities ahead of resolution via official METAR at São Paulo airports.
