Trader consensus on Polymarket clusters around 27–29°C for São Paulo's highest temperature on April 5, mirroring the spread in latest INMET and CPTEC forecast models amid autumnal cooling trends. Recent INMET guidance for March 30–April 6 highlights persistent showers across Southeast Brazil's interior (20–50 mm weekly accumulations), introducing cloud cover and evaporative cooling that could suppress peaks to 27°C, while partial clearing and urban heat island effects favor 28–29°C. Differentiating factors include sea breeze timing—early enhancement boosts advection of warm air—and convective activity; afternoon showers tip toward lower outcomes, sunny intervals toward higher. Daily CPTEC updates expected by April 3–4 may refine model ensembles, with historical April averages near 26°C providing baseline context under transitioning ENSO-neutral conditions.
