Nazare is a beach-break! So, I guess when you factor the wave size in vs. how far offshore it breaks (not very) it could definitely be considered shore pound... geometrically speaking or something like that.
I will say this, and take it for what it's worth. Being an amateur photographer I have seen some odd compression in photos taken from far away with a zoom. It can make far away things look bigger than things in the foreground and make things look closer than they really are. Not saying that wave is not gigantic but its probably further out and lower down than it looks in the picture.
