Interesting. I would have thought North/Northeast would be the worst. Wouldn't that be directly against the current flow?
According to Chrisi's website, it is closed today. I don't know how actively she keeps up with it, though.
I am on vacation so was late updating website today.
Predominant winds come out of the east which is what we want because the island blocks the winds - the more easterly the winds - the flatter the west (where the dive sites are) is. The wind direction and speed affects surface conditions, not currents. Think of "norte's" and port closures as small craft advisories. The diving itself is unaffected, but docking, navigating and getting passengers on/off the boat are the problem which is why the port is closed during high wind events coming from west, NW or North.
