How to use this reading
Rio Grande helps confirm whether swell energy is reaching the Brazil area. Higher height with a longer period usually means more organized energy, while direction determines which coastlines receive that swell best.
For surf decisions, compare height, period and direction with your beach's local exposure. If the station does not report a variable, use the app to compare it with nearby model points.
