Latest ensemble forecasts from the Servicio Meteorológico Nacional (SMN) and global models like ECMWF and GFS indicate a high of 27°C as the most probable peak temperature in Buenos Aires on March 27, aligning with trader consensus at 53.5% market-implied odds. This reflects stable atmospheric conditions featuring a broad high-pressure ridge over the region, moderating southerly flows and limiting convective activity after recent daily highs in the mid-20s°C range. March climatology supports this outlook, with historical averages around 26.5°C amid the southern hemisphere's autumn transition and neutral ENSO influences. Model spread remains tight (±1°C), though new SMN guidance expected within 24 hours could refine probabilities near resolution. Secondary outcomes at 26°C (22.6%) and 28°C (14.0%) account for minor uncertainties in boundary layer mixing and cloud cover.
