Proceedings kick off at 2.30pm with sea swimming races, followed by the raft races themselves.
After the competitive events, the RNLI's inshore rescue crew will give a demonstration, subject to availability.
On dry land, spectators will also enjoy a barbecue, music, bar and ballots, with further entertainment in the White Cliff Inn from 8.00pm, including an appearance by local band Jinx.
Organiser Paul Abraham commented: "This is one of Whitehead`s most popular annual events and attracts big crowds from all around.
"There is something here for all ages and even if you don't participate directly it is hugely entertaining and a real fun day out."
Raft race day is hoted by County Antrim Yacht Club and sponsored by NK Fencing.
Fundraising for RNLI will take place on the day.
