Recent forecasts from agencies including INMET and international models highlight a southward surge of cooler polar air and a passing cold front suppressing daytime heating in São Paulo on July 4, shifting the expected maximum well below the month’s 21–22 °C climatological average. This airmass advection, combined with increased low-level moisture and variable cloud cover, creates the narrow spread among leading outcomes near 19–20 °C; small differences in frontal timing, surface wind speeds, and urban heat-island retention will determine whether boundary-layer warming reaches 20 °C or stalls closer to 18 °C. Ensemble guidance still shows modest spread in the 16–21 °C range, leaving traders focused on the final 24-hour model runs and any rapid changes in steering flow before resolution.
