Current forecast models from agencies like INMET point to a maximum near 26°C in São Paulo on August 14, supporting the close trader consensus split between 26°C (32%) and 27°C (30%) outcomes. In the Southern Hemisphere winter, a dominant subtropical high brings dry, stable air with limited moisture advection from the Atlantic, while urban heat island effects and variable cloud cover create small differences in peak readings. Historical August averages hover around 23–25°C, and recent stable conditions without significant frontal passages have kept probabilities tightly clustered; the next model updates or official observations will likely clarify whether slight warming from reduced overnight cooling pushes the high one degree higher.
