Parks Canada says surf conditions in P.E.I. National Park are considered dangerous Saturday, a day after a woman died while swimming.
The air temperature is 22 degrees, while the water temperature is 19 degrees.
"To ensure visitor safety, entering the water is not recommended in these conditions," Parks Canada said in a news release.
A 69-year-old woman from Washington, D.C., died Friday after she was caught in the surf 225 metres off the north shore.
She went swimming at Lakeside Beach behind the Crowbush Resort in the morning.
The woman was pulled from the waters off Crowbush by a search and rescue helicopter at 12:40 p.m. She was taken to Queen Elizabeth Hospital, where she was pronounced dead.
RCMP said strong winds and heavy surf conditions hampered recovery efforts.
Rip currents form when waves break near the shore and water piles up, then a narrow channel develops as the water tries to flow back to the ocean.
If swimmers get caught in a rip current, they're advised to stay calm and swim parallel to the shore to get out of the current, then swim to land.
