EMERGENCY services descended on Frinton beach following reports of three people - including a kite surfer - in difficulty in the sea.
Essex Police and East of England Ambulance Service are among those called to the scene, close to The Esplanade, on Sunday afternoon.
A spokesman from East of England Ambulance Service said multiple emergency response vehicles were sent to assist, including several ambulances, an air ambulance, hazardous response and a rapid response vehicle.
A coastguard spokesman said: "I can confirm that HM Coastguard was called at 11.12am to report of a kite surfer in the water.
"Clacton RNLI lifeboat attended alongside Coastguard Rescue Teams from Walton and West Mersea and a Coastguard rescue helicopter."
An RNLI spokesman said: "We can confirm Clacton RNLI’s Atlantic 85 David Porter MPS was launched at midday on Sunday to reports of three people in the water at Walton."
