Swell Summary

North and west-facing shore surf that peaked yesterday evening will gradually fall through the day with the fading northwest swell. A pair of moderate size, medium to long period north northwest swells are timed to arrive Tuesday into Wednesday and Thursday into Friday. An early week northwest swell originating from a compact hurricane force low east of Japan will begin filling in late Monday and peaking Tuesday. The later week north northwest swell coming from a broader area of gale force winds southwest of the Aleutian Islands may arrive and peak Friday. While the first swell origin's source is a deeper low, it is farther away and swell size may be compromised by angular spreading along its long eastern journey. The late week swell fetch area's gales are more in-line with the great circle route aimed toward the islands. This will probably be the larger of the two swells and may push surf to High Surf Warning levels as it arrives from a more northerly direction. Generally strong trades will continue to generate rough, choppy surf along east-facing shores through the day with a gradual early week decline as a result of weakening easterlies. A slight increase in surf along south-facing shores may occur later today and Monday with the arrival of a small, longer period southwest swell.
