Swell Summary

The latest buoy observations from Mokapu show the main swell energy focused across the 10-14 second spectral bands this afternoon. This swell will likely peak late this afternoon into the evening across Oahu and peak across Kauai later tonight. Surf heights should drop below warning thresholds by Wednesday morning, but advisory level surf could linger around Kauai through parts of the Wednesday.

A reinforcing swell out of the south-southwest arrived today and will be on a slow decline Wednesday into Thursday. Surf heights should hold near the summer average through Wednesday then drop below average by Thursday. Another small bump from the south is possible on Friday. Additionally, multiple small pules of northwest to north-northwest swell energy will generate small surf along north facing beaches throughout the week and into the weekend. A short-lived northeast swell is possible for select exposures as Kiko passes to our north.
