Swell Summary
Surf along north facing shores will remain tiny to small over the next few days as reinforcing small short-period north-northwest swells are expected. Otherwise, a small long-period northwest swell is possible towards the middle of next week. Surf along south facing shores will see background energy through the week before a small to moderate long-period south-southwest swell fills in and peaks on Sunday. A reinforcing south-southwest swell is expected to fill in on Tuesday, which should help maintain above average surf throughout the first half of next week.
Below average surf is expected to continue along east facing shores through the rest of the week. In the extended forecast, easterly energy from Tropical Cyclone Kiko is possible as early as this weekend. This will bring the potential for surf to reach High Surf Advisory criteria as early as Sunday or Monday. Warning level surf will be possible as Kiko moves closer to the Hawaiian Islands on Tuesday. Surf heights for Tuesday will be highly dependent on the track and intensity of Kiko as it nears the state.
