Along the main beach yesterday it was getting up to a two metre swell, she said.
"It did get up but around the other side, against the rock faces, it will be much larger.
"You are getting a three metre swell."
People needed to be mindful of when the tides changed, she said.
"We hope that people do use their common sense, if they are avid fishermen adhere to all the rules.
"Wear a lifejacket, even if you are standing on the rocks. Wear a lifejacket."
People needed to be totally prepared with all the safety equipment, she said.
Locals had previously campaigned against fishing in that spot, she said.
At this stage it was anticipated that the search will continue until after low tide.
Police were alerted at 1.30pm yesterday that a 17-year-old had been swept into the water at Papanui Point in Ruapuke. The spot has reportedly claimed close to 20 lives in the past 75 years.
The teen was with three other people.
