if the wind is coming from the North, then yeagh.. but if its an Easterly direction (normal trade winds for the area) ..then only like Cabarete/ kite beach will be noticeabley Windy.. Those Hotels + the cliff on the east side of Sosua beach, you would be surprised how much WIND they totally slap down..
Anyone who fishes in Capes Peninsulas or islands fully understands this Effect.. its most dramatic.. if anyone here has ever been to Montauk NY for example, one side is HONKING at 35+ Mph .. the other side can be as Flat as a pond. Its most dramatic when you see it that way.
Aruba is a perfect Island example, although I have never been there myself.. They have trees that are literally bent from all the wind on the Windy side of the island.
