Donaghadee's All-Weather Lifeboat, Saxon, launched at about 8pm after reports of objects in the water off the coast of the Copeland Islands.
It arrived at the scene within 15 minutes.
A witness had described what appeared to be people in the water.
The crew found a bunch of helium-filled party balloons which had come down in the sea.
Lifeboat coxswain Philip McNamara said: "While this was a preventative operation, the lifeboat volunteers prefer to attend at an early stage to avoid any risk to life.
"An object in the water can be a danger to shipping."
