Nobody likes to swim with jellyfish... Some sting, some are just there for decoration, but there are generally no people bathing when they are here!

Thanks to the Jellyfish Alerts app, the time when you arrived on the beach and were surprised is over! Launch the app, have a look to the most recently posted alerts on beaches around you.

How does it work?
You are on the beach, and see one (or more) jellyfish in the water? Report it by posting an alert to the community directly from your smartphone or from the website www.alerte-meduses.fr. Reports are geo-located and will allow other users to not be surprised.
