Dublin Fire Brigade and Irish Water Safety have warned people against performing "unsafe" water stuns during this week's sunny spell.
They were commenting as video footage from Dublin city centre showed some young people using the good weather on Tuesday afternoon to jump off bridges into the River Liffey.
The footage showed several people jumping off the Samuel Beckett Bridge into the Liffey.
A Dublin Fire Brigade spokeswoman said jumping into the River Liffey posed serious risks.
“Dublin Fire Brigade would advise caution in this hot weather; always take care around water, even if it’s slow-moving and shallow,” she said.
She said the Dublin Fire Brigade saw a surge in river-rescue incidents during warm weather.
So far this year, the Dublin fire service has been called out to 96 water-related incidents.
“Do not swim in unsafe areas such as canals, especially locks where there are hidden dangers. Remember, alcohol impairs judgment, balance and co-ordination, all essential for swimming,” the spokeswoman said.
Precautions
John Leech, chief executive of Irish Water Safety, said people needed to take precautions around the water, and should not take risks just because of the good weather this week.
“Irish Water Safety is advising anyone planning to visit the beach, swimming pool, lakes [and] rivers during the current good weather to take precautions,” he said.
Alcohol is involved in 30 per cent of drownings, Mr Leech said, adding that people should “stay away from the water” if they have had a drink.
“Children should be supervised near water at all times and swimmers should remain within their depth while in the water. People should only swim in traditional bathing areas,” he said.
