Trader sentiment clusters tightly around 29–31°C for São Paulo's March 22 high temperature, driven by divergent short-range forecasts from global models amid a stable high-pressure system over southern Brazil. ECMWF ensembles project a 29°C peak under increasing afternoon cloud cover and sea breeze influence, while GFS runs favor 30–31°C with clearer skies enhancing urban heat island effects in the city. INMET's latest outlook aligns at 30°C, matching the 27% implied probability, as recent days averaged 29.5°C with diurnal ranges of 8–10°C. Differentiating factors include onshore wind strength—potentially capping at 29°C if exceeding 15 km/h—and minimal rain risk (10%), per satellite moisture data; monitor 12Z model runs for shifts.
