Trader consensus on Polymarket reflects deep uncertainty in short-range forecasts for São Paulo's highest temperature on April 5, with 28°C and 32°C or higher both at 25.5% implied probability amid divergent model outputs. Climatempo's latest 15-day outlook projects a high of 25°C under partly cloudy skies with no precipitation expected, aligning with INMET's weekly forecast of 20-50 mm accumulated rain in central São Paulo through April 6 from persistent Southeast moisture and sea breeze convergence, which typically caps daytime heating. However, some global ensemble members from GFS and ECMWF suggest possible afternoon clearing, enabling urban heat island amplification toward 32°C outliers. April climatology averages 25-27°C highs, but frontal system timing introduces volatility; watch daily INMET/CPTEC updates for resolution-defining shifts in cloud cover and insolation.
