Recent forecasts from multiple models indicate Sao Paulo's overnight minimum on August 25 will likely fall between 13–16°C under persistent low-level cloud cover, light southeasterly winds, and high humidity near 85–93%, limiting radiational cooling. This range aligns closely with the August climatological average low of roughly 12–13°C at the Mirante de Santana station. Subtle differences among leading outcomes stem from small variations in forecast boundary-layer mixing, exact cloud thickness, and dew-point depression, which can shift the minimum by 1–2°C. No strong polar air mass or clear-sky conditions are expected to push readings toward 11°C or below, nor is warmer advection likely to support 17°C or higher. Market-implied odds cluster tightly because updated model runs continue to show comparable cooling potential through sunrise.
