It's safe to go back in the water, the jellyfish have gone

It's safe to get back in the water.

The "all clear" has been tweeted by Dun Laoghaire-Rathdown Council.

Not a single deadly Lions Mane jellyfish has been spotted along the Dublin coastline for the past five days.

So feared has the large, yellowish jellyfish become that the council took to Twitter yesterday to assure swimmers that the coast was now clear.

Lions Mane jellyfish can cause severe allergic reaction with their shocking sting.

Their appearance has closed several beaches along the Dublin coast this summer.

At one point last month Council workers removed 77 of the jellyfish from south Dublin beaches.

They were also spotted on the northside where swimmers were warned with red flags not to enter the water for several days.

The creatures, whose sting can cause anaphylactic shock leading to death in some cases, tend to be seen in late summer when sea currents pull them near the shore at the end of their one year life span.

Warning

A Dun Laoghaire-Rathdown Council spokesman confirmed to the Herald that no Lions Mane jellyfish had been seen on council beaches for the past five days and the warning notices had been removed.

The jellyfish were spotted on Dollymount beach on July 28 but none have been seen there since, according to Dublin City Council.

Fingal Council put a red flag on Claremont beach last month after council staff removed several of the dangerous jellyfish from the area.

All three councils have now confirmed that there have been no sightings of the creatures in recent days.

Merrion Beach, however, has been closed by the city council since yesterday until test results next Wednesday because of water quality issues.

The councils have also warned swimmers that the bathing season ends on September 14 and beaches will no longer be patrolled by lifeguards after this date.
