Trader consensus has locked in at 100% for a high of 26°C in Sao Paulo on March 19, driven by official observations from Brazil's National Institute of Meteorology (INMET) and airport weather stations, which recorded that exact peak amid cloudy conditions and scattered showers suppressing temperatures. This aligns with seasonal norms for autumn in the region, where March highs typically range 26-28°C, influenced by cooler southerly winds from the Atlantic. Supporting model forecasts from ECMWF and GFS had converged on this outcome days prior, reflecting accurate depiction of frontal systems. Realistic challenges would require verified data revisions from alternative stations like Campo de Marte, but INMET's standardized measurements render such shifts improbable.
