Trader consensus overwhelmingly favors a high of 24°C or below in Buenos Aires on March 21, driven by ensemble weather models from the Servicio Meteorológico Nacional and global forecasts like ECMWF, projecting a maximum around 22-24°C amid cool southerly winds and partly cloudy skies. Historical March data shows average highs near 25°C, but current upper-air patterns suppress temperatures, with sea surface temperatures off the coast also cooler than average. This positioning aligns with verified short-range guidance, where 99.8% market-implied probability reflects low model spread. Realistic challenges include an unforeseen northerly wind shift or urban heat island effects inflating airport readings, though probabilities remain under 0.2% per model clusters.
