Dun Laoghaire-Rathdown County Council has put up warning signs in the lifeguarded area of Sandycove in south Dublin after sightings of lion’s mane jellyfish in the water.

Though the notice was put in place yesterday (Thursday 13 June), it’s emerged there have been sightings of the venomous marine wildlife since mid-May.

Bathing has not been prohibited as it was with the water quality warning earlier this month.

But swimmers at Sandycove and further out in Dublin Bay are advised to proceed with caution for the time being.

As an added precaution the lifeguard warning flags are on red and will remain in place till further notice, the council says.

Lion’s mane jellyfish carry a painful and potentially lethal sting, even when washed up on the beach.

Last summer saw more than 150 lion's mane jellyfish recorded along the West Coast — amid a spate of incidents with swimmers being stung in Galway Bay.

But the East Coast was not immune, as a teenager was hospitalised after he was stung over most of his body off a Co Louth beach.

We've got a favour to ask

More people are reading Afloat.ie than ever thanks to the power of the internet but we're in stormy seas because advertising revenues across the media are falling fast. Unlike many news sites, we haven’t put up a paywall because we want to keep our marine journalism open.

Afloat.ie is Ireland's only full–time marine journalism team and it takes time, money and hard work to produce our content.

So you can see why we need to ask for your help.

If everyone chipped in, we can enhance our coverage and our future would be more secure. You can help us through a small donation. Thank you.
