Official observations from Argentina's Servicio Meteorológico Nacional (SMN) confirm Buenos Aires' highest temperature on March 26 reached 28°C at the Aeroparque station, the primary reporting site for such records, aligning perfectly with the market's 100% implied probability on this outcome. This measurement reflects mild autumn conditions influenced by a stable high-pressure system suppressing heat advection, consistent with recent forecast model consensus from GFS and ECMWF runs that projected daytime highs in the upper 20s°C amid light southerly winds and partial cloud cover. Trader consensus, backed by real capital, solidifies around this verified data point, with negligible odds on higher temperatures due to the absence of heatwave indicators like northerly foehn winds. Only an improbable post hoc revision from SMN—such as equipment recalibration—could challenge resolution, though official finalization is expected imminently.
