Swell Summary
Latest buoy observations from Hilo showed a rise in energy across the 12-14 second spectral bands this morning, but since then the energy has been steady this afternoon. With Kiko expected to make its closes approach to the Hawaiian Islands during the next 24-36 hours, we should see a quick rise in wave heights starting with the eastern half of the state tonight and the western half of the state on Tuesday. Although peak surf heights are expected to be short-lived, a rapid rise of east swell should produce dangerous conditions along east facing shores. A High Surf Warning has been issued for the Big Island, Maui, and Molokai starting tonight and for Oahu and Kauai starting Tuesday. Surf heights are expected to peak at low end warning thresholds tonight for the Big Island, late tonight into Tuesday morning for Maui County and Tuesday mid day into the afternoon for Oahu and Kauai.
The current medium period south-southwest swell will slowly decline this afternoon before another reinforcing swell out of the south- southwest is expected on Tuesday. This should help maintain surf near or slightly above the summer average throughout the first half of the week. Additionally, multiple small pules of northwest swell energy will generate small surf along north facing beaches throughout the week. A short-lived northeast swell is possible for select exposures as Kiko passes to our north.
