Swell Summary
The short period east trade wind swell will peak today into tomorrow and then gradually lower through the week. This will be in direct response to weakening trades that will transition to light southerlies through mid week with the approach of a front northwest of the state. A High Surf Advisory (HSA) remains in effect for the exposed eastern shores of Kauai, Oahu, Molokai, Maui and Big Island through 6 AM HST Monday. An extension to this HSA may be needed through Monday afternoon. The small north northeast swell that filled in this weekend will linger through Tuesday. A couple of small, short period northwest swells will pass around the islands through Tuesday.
A small compact low approximately 800 nm south of the Aleutian Islands this morning will send the next appreciable northwest swell our way. This northwest swell is scheduled to arrive Tuesday night and travel down the chain through Thursday. Surf heights along north and west facing shores may reach low end HSA criteria Thursday during the swell's peak. This northwest swell will gradually subside Friday and Saturday. A series of storms south of New Zealand are sending pulses of long period swell energy toward the local waters. These very small, long period south swells could arrive as early as Tuesday night and provide a small boost to mid to late week south shore surf.
