Consensus from leading weather models like ECMWF and GFS ensembles pins the highest temperature in Buenos Aires on March 26 at around 27°C, fueling its 26.5% implied probability as traders weigh tight clustering near 26-28°C. Recent forecast updates from Argentina's Servicio Meteorológico Nacional (SMN) project a daytime peak of 27-28°C under a building subtropical high-pressure ridge, suppressing clouds and precipitation for above-normal autumn warmth—historical March 26 averages hover at 25°C. Differentiating factors include minor ensemble spreads (±1°C) from boundary layer mixing and urban heat effects, with low rain odds (under 10%) ruling out cooler 25°C or below scenarios, though late-day sea breeze could shave 0.5-1°C off peaks. Trader sentiment reflects this model convergence amid minimal volatility.
