Swell Summary
A large to extra large long period west-northwest has begun to fill in this morning that will peak tonight and Sunday for north and west facing shores. Due to the significant westerly component of this swell, shadowing could produce varying surf heights on Oahu and Maui County, and west facing shores of the Big Island all the way up to Mahukona will experience significant impacts, including overwash onto vulnerable coastal roadways and beaches. This swell will decline Sunday night and Monday, followed by a smaller pulse of west- northwest swell Tuesday and Wednesday.
Surf along east facing shores will remain small into next week due to a lack of easterly trade winds upstream of the islands. A small pulse of south-southwest swell will fade Saturday, with little to no southerly swell expected through the rest of the week.
