Newcastle RNLI’s inshore lifeboat Eliza and her volunteer crew were tasked along with members of Newcastle Coastguard, local PSNI and their air support helicopter to the area shortly before 9pm last night.
It followed reports from four women who were walking on the beach that there may be a person in difficulty in the water.
A comprehensive search was carried out for almost two hours before the operation was stood down with nothing found.
Newcastle RNLI volunteer lifeboat helm Nathan Leneghan said: “Conditions were ideal for searching with very few waves and just the right amount of sunlight.
“We know Tyrella is a very popular beach and with the favourable weather at the moment we advise people to always try to swim at lifeguarded beaches and respect the water.
“We would rather be called out for a genuine false alarm than be called out too late. These women took the right action and should be commended.”
Newcastle RNLI advises the public that if they see someone in trouble on or near the water to dial 999 or 112 immediately and ask for the coastguard.
