Trader consensus on Polymarket reflects short-range forecast models projecting São Paulo's highest temperature on April 8 around 28–29°C, with a tight spread capturing inherent uncertainty three days out. INMET and global ensembles like ECMWF and GFS show ensemble means near 28.5°C amid subtropical ridge dominance fostering subsidence warming, tempered by southerly sea breezes and residual soil moisture from early April showers. Historical April data indicates average highs of 26°C decreasing through the month, but urban heat island effects often add 1–2°C; ENSO-neutral transition from lingering La Niña supports typical autumn conditions without cooler biases. Watch INMET's daily updates and afternoon convective potential, which could shave 1°C off peaks via cloud cover.
