Buenos Aires: the Río de la Plata at Last Light

Buenos Aires faces east and northeast toward the Río de la Plata, one of the widest river estuaries in the world, giving the city a vast flat-water horizon. Puerto Madero, the waterfront district directly east of the city centre, sits at the water's edge; the Puente de la Mujer bridge and the converted red-brick docks frame sunset light from the west behind the city. The Costanera Sur ecological reserve extends south along the river and faces northeast: sunrise over the Plata here occurs over open water with no opposing shore visible. At -34.6°S, golden hour lasts about 37 minutes. Southern hemisphere seasons apply: peak conditions fall in the austral summer (December through February) when the sun rises northeast and sets northwest, and golden light lingers until after 8:30pm. Palermo park lakes provide ground-level reflections 5 kilometers west of the waterfront.
