Trader consensus on a 24°C high for Buenos Aires on October 4 reflects official station observations under clear to partly cloudy skies and light northerly flow, with daytime warming reaching that exact peak amid a stable high-pressure ridge. Southern Hemisphere spring conditions produced a daily range from roughly 11°C overnight to the recorded maximum, aligning with model consensus from agencies tracking surface temperatures and consistent with recent dry, mild patterns following earlier instability. This outcome carries near-certainty because verified measurements have already closed the window for revision, though minor discrepancies in microclimate reporting or post-analysis adjustments remain theoretically possible before final certification.
