Swell Summary
The current northwest swell is on the rise and expected to produce warning level surf along north and west facing shores today and into Wednesday. Surf should rapidly rise today, and likely peak tonight through Wednesday. As this swell declines late Wednesday through rest of the week, the swell direction will veer more northerly Thursday into Friday. For the Big Island much of this swell will be blocked by the smaller islands, however, surf low end advisory surf is expected today through Wednesday.
Along south facing shores, a series of south-southwest swells will keep surf well above the October average through much of the work week. The current south-southwest swell will be reinforced by a slightly larger south-southwest swell Wednesday into Thursday. East shore surf will generally remain small during the next 7 days, but surf breaks exposed to wrap from the northwest or the south should see larger surf.
