Current forecasts from multiple models indicate a daily high in Buenos Aires on June 21 likely between 13–15°C, with trader consensus split between the top two outcomes reflecting model spread and limited warming potential under mostly cloudy skies. June climatology shows average highs near 15°C, but recent days have trended 1–2°C cooler amid stable high-pressure influence and light northerly flow. Key differentiating variables include the degree of cloud cover reducing daytime heating, any weak frontal passage, and precise timing of maximum solar radiation. Official guidance from Argentina’s Servicio Meteorológico Nacional and international ensembles will update overnight, with resolution hinging on the official recorded maximum at the central observatory.
