Trader sentiment clusters tightly around 28–30°C maxima for São Paulo on March 23, driven by converging short-range forecasts from INMET and international models like GFS and ECMWF, which project peaks of 27–31°C amid mild autumn conditions. Leading 30°C (25.5%) edges 28°C (25.0%) due to urban heat island amplification and reduced sea breeze influence in drier recent patterns, while 29°C (22.5%) holds as consensus from ensemble means. Differentiation hinges on cloud cover variability—less convective activity favors 30–31°C (19%) via higher insolation, but lingering soil moisture from prior rains could cap at 28°C via evaporative cooling. Historical March 23 averages 28°C, with low odds for extremes reflecting stable subtropical high pressure.
