EIGHT paddle boarders swept out to sea in wild weather have been rescued from a bay southwest of Melbourne.

They were swept into Corio Bay from North Shore, Geelong, when a severe weather front hit the area just after 3.15pm (AEDT) on Sunday.

The paddle boarders, aged between 40 and 60, were found by helicopter in the water near Point Wilson, with one clinging to a channel marker.

The group was rescued by Coast Guard.

Two of the paddle boarders were treated at the scene for mild hypothermia.

Gusts of up to 50 knots and waves over two metres were recorded, police said.

Water Police Leading Senior Constable Felicity Bell said police were relieved the paddle boarders were found safe.

"This rescue should act as a warning to all about how quickly conditions can change out on the water," Leading Sen Const Bell said.
