Recent short-range forecasts from Brazil’s INMET and global ensembles have clustered São Paulo’s August 24 maximum near 19–21°C, driving the tight market spread around those outcomes. Cooler-than-average conditions stem from increased cloud cover limiting solar insolation, moderate southeasterly winds enhancing mixing, and lingering moisture from a passing frontal boundary suppressing daytime heating. These factors differentiate the narrow band from the historical August mean of roughly 23°C. Model consensus on minimal diurnal warming and stable atmospheric profiles sustains trader focus on the 19–21°C range ahead of official verification.
