As you enter Rafina from Marathonas Avenue you make a right at the T which is the "center" of the town. Make a left at the first traffic light. You cant miss the beach it infront of you. Plenty of parking. As you do in Greece , make your own parking space. You will see a walking bridge that crosses a polluted stream. Cross this little bridge and continue walking towards the beach. If you know anything about waves you will see how the waves form off of a cliff/rocks that follow the coastline after the sand.
The only danger are the windsurfers.Rafina has good wave only with strong north winds.Strong wind for days is the only way your going to get a ridable wave here. The wind has to blow strong from the North - North east.
Overview
Atmosphere
I was religiously studying ,checking weather and wave direction.http://www.oc.phys.uoa.gr/dok1.htm Very rare but when the conditions are right its pretty intense. Go here if your bored and unemployed. Or dont feel like going for coffee like everybody does.dont be suprised if you visit here and its flat like a lake. I did not have a surfboard so I made a body board from insulating styro foam.
