Yes.
But if you need extra weight to be able to cast, then use a sinker to help with casting. Just use a small sinker.
If you do need to use a sinker, then a ball sinker will help avoid snags. But there is no way to completely avoid snags.
In rough water like you describe, the fish do not expect food to sink to the bottom. The fish expect food to be floating and washing back and forth with the waves.
An example might be the drummer we get here in Australia. They like to eat what we call cabbage weed. They also like to feed in rough choppy waters. The waves slam into the rocks and brake off the cabbage weed turning the water into "cabbage soup". So anything in the water that does not look like cabbage weed will be ignored. A big clump of cabbage weed on a hook looks natural, but if it had a sinker it would sink to the bottom and be ignored...and get snagged.
Those choppy waters also attract pelagics like tailor, kingfish, queenfish, barracuda, banito etc. The waves hitting the rocks wash all sorts of things into the water which attracts small bait fish...which attracts bigger fish. So casting some shiny metal lures with a fast retrieve is also worth a try.
