Recent forecast model consensus from sources like GFS and ECMWF points to a peak high near 29–31°C in São Paulo on July 29, driven by clear subtropical winter skies, light winds, and minimal cloud cover allowing strong daytime solar heating, with traders pricing tight spreads around these values due to minor run-to-run variability in exact maximum timing and urban heat island effects at the official Guarulhos station. Historical July baselines average 22–24°C, so this warmer pattern reflects transient high-pressure dominance rather than broader seasonal shifts, though ensemble spreads introduce realistic uncertainty around resolution thresholds.
