**Forecast models for São Paulo on August 25 point to overnight lows clustered near 9–14°C, producing closely matched market probabilities around 13–16°C as the most likely outcomes.** Winter conditions in the subtropics feature clear or partly cloudy skies that enhance radiative cooling after sunset, while light winds and low humidity allow temperatures to drop further than on cloudy or breezy nights. Recent model runs show modest differences in the strength and timing of any weak frontal boundary or high-pressure ridge, which can shift the minimum by 1–2°C depending on whether cold air advection or subsidence dominates. Historical August minima in São Paulo average near 12–14°C, providing context for the current distribution. Traders weigh the latest operational runs from global models against local observation networks, with updates on cloud trends or wind shifts expected to refine probabilities before resolution.
