Agree on that.
We have been there last spring and the diff in both wind and waves can be huge.
I had some really nice windsurf sessions on Inch beach (with a big thanx to the guys at Jamie Knox for the tip) and some unexpected ones at Kilcummin due some kin of thermal wind falling down of the green hills
SUP sessions allover the bay as well on Inch Reef...:P
If you have a Sup or Canoe and there are no wind or waves..go to Slea head paddling between the whales, seals and Dolphins.
if you don,t have any, there is an eco-boattour going there well worth the 20,-
