Lion’s Mane jellyfish have been spotted on a number of popular beaches along the Irish coastline, with sea swimmers warned of harsh stings.

The increase in jellyfish blooms is being put down to climate change and extreme weather conditions, from the bitterly cold temperatures in March to the scorching hot summer.

Others believe overfishing of jellyfish predators doesn't help.

Jellyfish are most likely to be seen from mid-spring through to late summer and early autumn, depending on species and the weather.

There are five native jellyfish species to NI’s coastal waters:

• Moon

• Barrel

• Compass

• Blue

• Lion’s Mane

So if you’re a keen sea-swimmer, it’s important to stay vigilant when on the beach or in the water.

What to do if you get stung by a jellyfish?

You may have heard the myth that applying urine to a jellyfish sting can counteract the venom, but there is no scientific basis for this “remedy” and it can sometimes actually make the sting hurt more.

Here’s what you should do:

1. Rinse the sting with seawater or create a paste of baking soda and seawater to get rid of the tentacles. If you’re able to, bathe the area in heated tap water or take a warm shower.

2. Remove any leftover tentacles with a dry towel. If the tentacles are difficult to remove, try coating them with shaving cream, then shaving them off with a razor or credit card. Protect your hands with gloves if possible.

3. Protect the site of the sting. Avoid pressure and contact with sand.

4. Taking pain relievers like ibuprofen or applying antihistamines or steroid creams (like cortisone) can lessen the pain, itching, and swelling.

If you have these symptoms, seek medical attention:

  • Numbness or dizziness
  • Swollen lips and eyes
  • Developing a rash
  • Tightness in your chest
  • Trouble breathing or swallowing
  • Nausea and vomiting
  • Signs of shock, such as pale skin, quick pulse, or passing out

Before you go for a dip, it’s important to know how to swim safe in the sea.

  • Don’t jump into water you have not checked for depth and obstructions
  • Make sure you know how you will get out before you get in
  • Never swim alone and keep a constant watch on weak swimmers
  • Come prepared with warm clothes before and after a swim
  • Never swim in urban rivers, stagnant lakes or reedy shallows
  • Wear footwear if you can
