Current forecasts for Buenos Aires on August 30 point to a mild winter night with minimum temperatures likely ranging 8–12°C, driven by light easterly to northeasterly winds, stable high pressure around 1018 hPa, and mostly clear to partly cloudy skies that limit strong radiative cooling. Official model runs show lows near 10–12°C under gentle advection from the Atlantic, though some guidance dips toward 8°C if clearer conditions enhance overnight heat loss from the urban surface. Historical August minima average around 7°C, but the absence of cold fronts or strong southerly flow this week keeps probabilities clustered near 7–12°C outcomes. Traders weigh these subtle differences in boundary-layer mixing and cloud timing ahead of final observations.
