Official meteorological observations confirm that the daily maximum temperature in Buenos Aires reached 15°C on June 9, aligning precisely with long-term seasonal averages for early winter in the region, where typical highs range from 14–16°C under stable high-pressure systems and moderate southerly flow. Trader consensus at 100% for this outcome reflects verified station data from the Servicio Meteorológico Nacional, with no model discrepancies or anomalous warming events reported in the preceding days. Minor uncertainty in rounding or microclimate variations at specific stations could theoretically prompt a revision, though such adjustments remain rare once initial quality-controlled readings are released.
