Swell Summary
Surf observations continue to show advisory level surf affecting south facing shores today. A High Surf Advisory remains in effect through Tuesday afternoon, during which time the swell is expected to hold and keep surf at lower-end advisory levels. This swell will then slowly fade during the middle of the week. A new long-period south swell arrives Tuesday night, builds on Wednesday, and peaks on Thursday, keeping surf elevated above the summertime average through the weekend.
Surf along east-facing shores will remain slightly below seasonal levels today through Wednesday as the trades ease upstream of the islands. East shore surf should then build back close to seasonal levels late this week and through the weekend as stronger trades return over and upstream on the islands. Additionally, swell generated by former tropical cyclone Elida may give a slight boost to east shore surf during the middle of the week. This weekend, larger surf for east shores generated by Tropical Storm Fausto is possible.
Surf along north-facing shores will remain at flat to tiny levels through the weekend.
