Recent forecasts from meteorological services indicate Sao Paulo's August 24 maximum will likely fall between 19–21 °C under persistent cloud cover and a southeasterly flow advecting cooler maritime air. A recent cold-air intrusion and elevated pressure have suppressed insolation and kept daytime peaks below seasonal normals near 23 °C, with light drizzle or garoa further limiting warming. Model consensus shows afternoon temperatures cresting near 20 °C before declining, creating tight implied probabilities around 19–21 °C. Minor differences among leading outcomes hinge on exact cloud-break timing and boundary-layer mixing, while lower-probability tails reflect uncertainty in whether brief clearing could push readings to 22 °C or keep them capped at 18 °C.
