AVALON, N.J. (CBS) – This is the time of year that tens of thousands of people escape the city heat by retreating to the waves of the Jersey shore, but as pretty as it is, there’s some danger there too.

The ocean dynamics are changing because of climate and other factors, which could put an unsuspecting person at risk.

Captain of the Avalon Beach Patrol Murray Wolf, whose been on that beach for 57 years, says there is always something going on.

“We have lately more neck injuries with people bodysurfing. Now we have gullies that we have to watch with people swimming out to the sandbars, and when the tide comes in we have to pull them in.”

Wolf says those gullies by the sandbars can pose quite a danger, particularly to kids.

“The water looks calm, but then it runs pretty hard through the gullies. We try to really pay a lot of attention for children between the ages of two and six years old in those gullies because I think some parents are really aware of those types of dangers when they see the calm water.”

Wolf advises parents to keep a close eye on their children at all times and make sure their kids always stay in front of the lifeguard stand.
