Just got back yesterday (sailed June 13-23rd). Jellies were everywhere with the exception of the Baths, Anegada, White Bay, and Cane Garden. We would send the men in to do a "jelly check" before snorkeling. The stings weren't too bad; felt more like a small prick vs. full on jelly sting. All of us ended up with red welts all over (similar to mosquito but a tad more painful and itchy). Snorkeling was worth it though and nothing a Benedryl won't fix. This was my seventh time down there and the first time I have ever encountered the number of jellies in the water. They ranged in size from two to four inches. A little disappointing for the newbies on the trip but means they need to go back!
