The Health Department has issued advice to anyone who is stung and has said that the creatures may be particularly prevalent along the north coast.
Caroline Maffia, assistant director of Environmental Health, said: ‘Anyone who swims or spends time on the beach should be aware that jellyfish remain present in the waters around Jersey and that there is a risk of being stung, especially along the north coast.
‘While a jellyfish sting is highly unlikely to have serious consequences, stings can be painful, particularly for anyone who receives multiple stings.’
Anyone who is stung by a jellyfish should remove themselves from the water, pour seawater over the sting and apply a ‘cold compress’ or ice wrapped in a cloth to sooth the affected area.
Local anaesthetic gels and other forms of pain relief can also be used should the pain persist.
However, Islanders have been warned against using vinegar or urine to treat stings. According to the Health Department, this is no longer recommended by experts. Anyone in need of emergency assistance should call 999.
