This is what beachgoers in Atlántida had yesterday afternoon: brown fresh water waves, a patch of salt water twenty meters in, then more brown fresh water until about 200 meters out.
This because the brown fresh water of the Rio de la Plata moves up and down the coast depending on currents. At best we get greenish ocean water, but never the real blue of further east.
Little brown waves still take a little getting used to.
