Latest forecasts from Brazil's Instituto Nacional de Meteorologia (INMET) and Climatempo peg São Paulo's highest temperature on April 18 at 29°C, under partly cloudy skies with a 60% chance of afternoon showers from sea breeze convergence—driving trader consensus toward that outcome at 29.5% implied probability. Slightly warmer 30°C odds (21%) reflect potential for reduced cloud cover in global models like ECMWF ensembles, while 28°C (18%) accounts for stronger convective suppression capping peaks. April 2026 trends show above-normal temperatures from persistent high-pressure ridges over southeast Brazil, exceeding historical April averages of 25°C, but daily uncertainty persists in short-range model runs amid urban heat island effects and instability. New INMET updates expected April 17 could refine this tight race.
