The good news for bathers in Ibiza's warm summer seas is that there are far fewer jellyfish this year. This has been confirmed by the Red Cross which looks after beach safety and provides first aid, who say that they've had many less incidents of jellyfish stings this year than in the past.
The explanation has been provided by Diego Ponce, an oceanographer from San Antonio's Environment Department who says that there's a connection between the island's winter weather and the number of jellyfish by the shore.
The comparatively high rainfall last winter reduced the salinity of the sea water round the coast. This has formed a barrier to the salt loving jellyfish which have remained, for the most part, about one kilometre out to sea.
So, there you have it, every black cloud, does have a silver lining!
