Shock waves: this jellyfish is invading Irish beaches,

  • Currents and jellyfish warning
  • Five swimmers have died this year

Lions Mane JellyfishIrish Water Safety has warned swimmers to be aware of the Lions Maine Jellyfish which is being washed up on our beaches as this can cause anaphylactic shock.

The Lions mane Jellyfish has been reported on four beaches Portmarnock, Malahide, Sutton and Bettystown.

John Leech of IWS said due to the recent spell of good weather when more people will be enjoying our waters, these potentially dangerous jellyfish are likely to appear on more of our beaches in the coming weeks. The sting from these jellyfish can cause anaphylactic shock and we have had a number of people hospitalised as a result of a sting from these venomous Jellyfish. The sting from their tentacles lasts many days after they have died. Members of the public should report the sightings of these two jellyfish to the relevant local Authority Water Safety Development Officer. See website.

Five swimmers have drowned so far this year and the water safety body is appealing to the public to swim at lifeguarded beaches during hot weather.

August is the most popular month for outdoor swimming which can be enjoyed safely by heeding the following swimming safety tips:There is a full moon on August 18 so rip currents will be more prevalent on beaches: Lifeguards ensure your safety on our beaches and will be patrolling on their surf rescue boards to ensure that they do not pose a threat to members of the public.

Drownings often happen quickly and silently with 80pc of drownings occurring relatively close to the victim’s home. The range of aquatic activities is extremely varied yet what is tragically constant each year is the gender most at risk – males – tragically reflected in the fact that of the 122 drownings last year, 91 were male. Forty-five of the 66 accidental drownings occurred in the 20-59 year age group clearly demonstrating that it is not just children that are at risk. That said, 30 children aged 14 and under drowned in the last ten years.
