We were staying at Geejam and decided to hire their boat for a few hours to explore along the coast a bit. We had to see the Blue Lagoon of course and have a swim. My wife went in first and reported that the water was lovely and warm. I followed and shouted at her that it was not very warm where I was. We found that it moved from warm to cold as you swam around - caused by the water from the land mixing with the sea water. A very nice splash - although there didn't seem to be a lot to do on the shore.
