Most info about jellies in the BVI is that they are most prevalent 8-10 days after a full moon and mostly come during summer months. The last full moon was June 2, so it does not fit that pattern.

We are there in 28 days. By my calculations we should not have problems until the very last part of the trip. I'm sure I can find something to amuse myself as we will be at Guavaberry by then. I will get some Sea Safe just incase we encounter the rogue packs of jellies.
