Recent ensemble forecasts from agencies like the Met Office and local models indicate São Paulo highs of 30–32°C on August 20, with 31–32°C emerging as the narrow favorites amid low precipitation and moderate easterly flow. Dry winter conditions typical of August, combined with recent days reaching 27–28°C, support slight positive anomalies relative to the 23–25°C climatological average. Minor model spread on boundary-layer mixing and insolation under partly sunny skies creates the tight market split, as small shifts in timing or cloud cover could favor either outcome. Updated runs expected tomorrow will further refine the maximum before resolution.
