"When you consider that in the whole of last year - including summer - we had just 31, that's a massive increase in our workload - and it's forecast to keep growing," he said.
He said the spike in the number of people heading to the beach can be put down to human nature after what he described as a new-found appreciation for the water after the Covid-19 lockdowns.
Recent warm temperatures and sunny weather, as well as school holidays may also have resulted in more people heading to the beach.
"We only ask that this be done safely. But unfortunately, we've seen this wish to get back to the coast manifest in people not taking the right precautions or not staying within their abilities.

"The past week has shown just how many ways there are to get in trouble on the coast."
And that includes the east coast: on Sunday, Mangawhai Heads lifeguards had just finished a training exercise with a team from Waipū Cove when they spotted two girls stuck in a hole.
The pair were rescued by a lifeguard on a rescue board, with the help of a local surfer.
On Monday, emergency crews were called to Bethells Beach after reports that a fisherman had been swept off rocks at O'Neills Bay.
Police moved the search to a recovery phase after extensive searches over the week failed to find him.
On Tuesday, lifeguards were sent on an IRB to Whites Beach, north of Piha, after a woman fell into the water.
One person was flown to hospital in a serious condition, said police.
