The main town beach is just a continuation of Sunshine Beach, so the peaks can get punchy and hollow on small to moderate E swells. Stumers Creek often has the goods and thee are proper barrels on the good days. The two NE-facing rocky beaches of Point Perry and Three Bays need a bit of size to get going since they are sheltered from S swells and winds by Point Arkwright. Tidally dependant and a bit fickle, it is usually better at the main beach.
Parking quickly becomes a problem in summer. Get there early.
