Police are urging people to be mindful of their behaviour during the good weather.
It comes following a number of reports of beach parties on the north Northumberland coastline.
During the recent warmer weather, officers have been called to a number of incidents of drunken and anti-social behaviour, damage to beaches caused by barbecues and littering.
The Alnwick Neighbourhood Team is working with Northumberland County Council to tackle these concerns, but officers ask people to enjoy the good weather responsibly and respectfully.
Sgt Neville Wharrier said: “We are not trying to stifle anyone’s fun and we do want people to enjoy the good weather while it lasts, but I do ask people to be mindful of their actions.
“People are gathering to have barbecues and parties on our local beaches, which is leading to rowdy and drunken disorder and is causing damage to the beaches and dunes.
“We ask that people abide by the rules and don’t cause concern or inconvenience to others.
“I also ask parents to reiterate these messages from the police to their children and know their whereabouts and what they are doing.”
Sgt Wharrier is also urging local residents to contact 101 if they do have any concerns.
He added: “I want to reassure our residents that we are continuing to tackle community concerns and any issues our residents have. If you feel you are affected by anti-social behaviour or any other disorder then do contact us, we are here to help.”
