RNLI lifeguards saved four people in two separate rescues along the Causeway Coast during one of the hottest days of the year.
Two teenage girls were rescued in Co Antrim after they got caught in a rip current on Monday of last week.
On the same day, a lifeguard rescued a man and his son off a popular beach in Co Derry.
The two teenage girls were being pulled out by a rip current at Curran Point between Portrush's East Strand and Whiterocks beaches.
A lifeguard rushed to help the girls, who were struggling to breathe.
The lifeguard, Luke, pulled one girl on to a sled at the back of his rescue water craft and helped the other climb aboard.
Another lifeguard, Emily, later treated the girls for shock.
"Rip currents are very unpredictable," she said.
"You could walk out five metres into the one at Curran Point and you would lose your footing. It is so strong. If you are caught in a rip current, do not try to swim against it or you’ll exhaust yourself.
"Instead, if you can, swim parallel to the shore until you’re free of the rip, and head to shore. Always raise your hand and shout for help."
On Benone Beach, farther west along the Causeway Coast, lifeguard Andrzej rescued a father and son.
He noticed two heads in the water about 500 metres out of the safe swimming zone.
One of the men sunk beneath the water but Andrzej managed to pull him onto his rescue sled. He also saved the man's son.
"In the heat of the moment, my training kicked in and I just wanted to get them back on to the sand," he said.
"It could have been a very serious situation if I hadn’t seen them out swimming, and if the son hadn’t raised his arm for help.
"When you swim at the beach, try to stay as close to the lifeguarded patrol zone as possible, so we can see you and get to you as quickly as we can.
"Luckily, the son knew what to do and did the right thing. If you get into difficulty in the water, lean back, stretch out your arms and legs, then call for help or raise your arm."
