**Forecast models from sources like BBC Weather and weather25 point to a daytime high of 10–11°C in Buenos Aires on June 14, 2026, aligning closely with the market’s leading outcomes.** Winter conditions in the Southern Hemisphere typically bring mild highs of 12–16°C on average, but a recent cool air mass and light southerly flow off the Río de la Plata have suppressed temperatures. Clear skies overnight have allowed efficient radiative cooling, while limited daytime mixing and light winds have kept maximum readings near or below seasonal norms. Model consensus emphasizes these factors over warmer onshore influences that sometimes elevate readings, explaining why probabilities cluster tightly around 10°C (31%) and 11°C (48.5%). Updated short-range guidance shows no significant warming trend or frontal passage before the daily maximum is reached, keeping the 9–12°C band dominant. Traders are weighting the most recent official forecast runs, which continue to resolve in this narrow range.
