In the north of Portugal there are several rip currents in the beaches and every year there are this sort of videos explaining how to escape and to avoid it.
I am a terrible swimmer and i never try to swim in the sea, I showed the videos to my kids and my husband also explain them how to act if they are caught in a rip current. One thing to have in mind is always go to beaches whwre there is life guard and follow their instructions as they always mark the risk places to swim.
