Current forecasts from meteorological models point to an overcast, rainy day in São Paulo on July 24 that should cap maximum temperatures near 17–18 °C. Persistent cloud cover and showers, linked to a passing frontal system, reduce solar heating and enhance evaporative cooling at the city’s 760 m elevation, keeping surface readings below the July climatological average of 21–22 °C. Recent model runs show only modest warming potential if breaks in the clouds occur during peak afternoon hours, creating the tight clustering of market-implied odds around the two leading outcomes. Traders are weighting the latest high-resolution guidance on precipitation timing and boundary-layer moisture, which remain the key variables that could shift the daily maximum by 1 °C in either direction before official station data finalize the result.
