The spot
The things that stay true when the weather changes.
Roughly May through October, when DLNR calls the water generally calm, though surges are possible. Winter belongs to big-wave surf, and DLNR calls winter current and wave conditions extremely dangerous across the district.
Free county beach park lot at 61-031 Kamehameha Highway. DLNR notes parking is available at both Waimea Bay and Pupukea beach parks.
