The marine protection organisation Aula del Mar is expecting fewer jellyfish on the shores of the Costa del Sol this summer, after an abnormally high presence last year.
Biologist Jesús Bellido explained that 2018 was an unusual year with massive and frequent invasions of jellyfish disrupting bathing.
In contrast, this season is expected to be "normal" with two or three days of incidents. Bellido explained that the key is not knowing why there are fewer now, but why there were so many last summer.
"Jellyfish are typically abundant, but the sea currents, the wind and reproductive phenomena can cause aggregations, and when they arrive on the beaches they affect bathers," said Bellido.
"It is a very complicated issue and we have little capacity to predict it," he continued.
The biologist recommends following the mobile app Infomedusa, which offers real-time information about the presence of jellyfish on each beach, thanks to the collaboration of users and volunteers, as well as lifeguards and researchers at Aula del Mar.
