Official observations from São Paulo-Guarulhos International Airport confirm a daily maximum of 17°C on May 22, aligning with the market's near-certain consensus on that outcome. A stable high-pressure system and moderate southwesterly flow limited daytime heating during the region's subtropical autumn, consistent with seasonal baselines around 22°C and recent model runs from INMET, ECMWF, and GFS that projected modest highs. This positioning reflects verified station data rather than forecasts, though minor discrepancies in microclimate readings or reporting adjustments could theoretically affect edge cases in similar temperature markets.
