Alerts & advisories

Weever fish

Lesser weever fish bury themselves in wet sand around the low-tide line in summer and have venomous dorsal spines. Wear beach shoes and shuffle your feet in the shallows. A sting is intensely painful but rarely serious: immerse the foot in water as hot as you can tolerate (about 40 C) for 30-90 minutes and seek help if a spine remains or swelling spreads.

Rip currents on surf beaches

The open Atlantic strands generate strong rip currents, particularly around low tide and after big swell. Swim between the red-and-yellow flags at lifeguarded beaches in season, never alone, and if caught in a rip do not swim against it: raise a hand, float, and let it carry you out until it releases.

Midges and clegs

Biting midges and clegs (horseflies) are worst on warm, still, overcast days and around dawn and dusk from late spring to early autumn, especially near dunes, marram grass and standing water. A breeze off the sea keeps them down. Cover up or use repellent at the back of the beach.

Jellyfish

Lion's mane and compass jellyfish are common off the Northern Ireland coast in summer and are often blown inshore and stranded after onshore winds. Lion's mane stings can be severe. Do not rub a sting; rinse with seawater, remove tentacles with a gloved hand or card, and use hot water or a cold pack for pain.

Seasonal dog restrictions

Many Northern Ireland councils restrict dogs from the main bathing area, or require dogs on leads, between 1 May and 30 September (Blue Flag beaches usually exclude dogs from the bathing zone entirely in season). Rules and dates vary by beach and council: check the signage at the entrance and your council's bathing-beach byelaws.
