Forecasts from major models for Buenos Aires on June 17 point to a daytime maximum near 14–15°C under easterly flow and partly cloudy conditions typical of mid-winter, keeping the market tightly split between those two outcomes. Recent model runs show limited spread due to stable high pressure and modest onshore advection off the Río de la Plata, which suppresses stronger warming while preventing sharp cooling. Historical June maxima average 14–15°C with a standard deviation of roughly 2°C, so small variations in cloud cover, wind speed, or the precise timing of any diurnal peak can shift the official Servicio Meteorológico Nacional reading by 1°C. No major synoptic changes are expected before measurement, leaving traders focused on the final 24-hour model consensus and local station data.
