How to read this data?

A 50 % probability does not mean the beach is "infested". It indicates that over several years, on this date, one out of two reports mentioned jellyfish presence.

• Jellyfish depend on sea currents. A beach can be exposed in the morning and completely spared in the afternoon.
• Water temperature plays a role, but is not the only factor. Citizen vigilance remains your best tool.
