A large number of jellyfish have been spotted across beaches in southern France, prompting local prefectures to warn people to stay alert.

The strong ‘Mistral’ wind has pushed the jellyfish closer to the coast, with sightings reported on beaches along the coast from Marseille (Bouches-du-Rhône) to Menton (Alpes-Maritimes).

Some jellyfish have even been seen on the sand after being pushed out of the water by the strong wind.

“There was a strong mistral blowing along the entire coast of Provence,” said Manuel Marchioretti, a doctor in marine biology, to BFM Toulon Var. “The conditions were favourable for bringing the schools of jellyfish that were offshore towards the coast.”

Local prefectures have warned beachgoers to be aware and avoid the jellyfish as much as possible, including being careful not to step on them, pick them up, or swim among them.

The jellyfish tend to be concentrated in just a few areas on each beach, which makes them easier to avoid. If you are able to sit and bathe in an area away from wind, or in the opposite direction to which it is blowing, you may be able to avoid them even more.

Happily for beachgoers, Dr Marchioretti said the phenomenon will last “48 hours, 72 hours at the most”.

In case of a sting, the Var prefecture advised the following:

  • Rinse the sting area with seawater (never fresh water, which can make the pain worse)
  • Clean the area without rubbing it, and take off any remaining tentacles if needed (do not use bare hands)
  • Put sand on the area and let it dry. Then scratch the sand off with something that has a rigid edge, like a postcard or piece of card
  • Disinfect the area with a disinfectant cream or wipe. Avoid touching or scratching the sting area and keep it dry.
  • If the pain continues and/or worsens, see a doctor.
