Latest forecast ensembles from GFS and ECMWF models show Buenos Aires' maximum temperature on March 29 clustering around 29-30°C at Ministro Pistarini International Airport, driving the tight trader consensus with 29°C at 24% and 30°C at 21.5% implied probabilities. Above-normal autumn warmth under La Niña conditions—historical late-March highs average 24-26°C—has elevated expectations, but uncertainty stems from variable sea breeze timing from the Río de la Plata, which could suppress peaks to 28°C if onshore flows strengthen early, or permit 31-32°C if delayed amid light winds and a high-pressure ridge fostering solar heating. Watch Servicio Meteorológico Nacional's 12Z update for refined guidance ahead of afternoon peak observations.
