Recent forecasts from sources including the Met Office and regional models show Buenos Aires highest temperatures on October 10 likely reaching 16–17°C under persistent cloud cover, southerly flow, and scattered rain that limits solar insolation. Springtime Southern Hemisphere conditions typically allow gradual warming, yet the current synoptic setup with elevated humidity and onshore winds suppresses peaks below seasonal averages near 19°C. Minor differences among 16°C versus 17°C or 18°C outcomes hinge on exact timing of any afternoon clearing or wind shifts, as numerical weather prediction ensembles still diverge slightly on boundary-layer mixing. Updated model runs over the next 48 hours will narrow resolution criteria for this daily maximum.
