Recent forecasts from global models and local guidance point to a daytime maximum of 11–13°C in Buenos Aires on June 23, driven by a cool southwesterly flow and limited daytime heating under partly cloudy skies. This aligns with mid-winter climatology where average June highs reach 14–16°C, but current conditions reflect below-normal temperatures from a passing frontal system. Ensemble spreads in the GFS and ECMWF runs create the tight split between 12°C and 13°C outcomes, as small shifts in cloud cover, wind timing, or boundary-layer mixing can alter the peak by 1–2°C. Official observations from the Servicio Meteorológico Nacional will resolve the market, with minimal precipitation expected to reduce variability. Traders weigh these near-term model updates against historical June extremes rarely exceeding 20°C or falling below 8°C.
