Just returned from AC 3 days ago;this year they are experiencing the wind they usually get in April, NOW. The water was so choppy and murky when we arrived(MAY 7) that hardly any boats were going out.The dry season is lasting longer than usual. However, by the 11th things had improved considerably-snorkel and dive trips going out,etc. Still very few sailboats or catamarans.Water looked great when we left the 14th.I suggest you be flexible w/plans-we shopped in San Pedro for a couple days,then went inland a day, then finally hit the water for snorkeling.
