Swell Summary

The north swell will be filling in around the islands through the day. The windward water nearshore PacIOOS buoys are moving up within the medium to long period bands thus confidence is growing that many north facing shores will experience double overhead surf in many sets today as this 6 to 7 foot medium period due north-in-direction swell peaks today. The northeast offshore buoy 51000 has been solid with 10 foot medium period swell. While quite the boost, north facing shore surf is expected to peak under High Surf Advisory (HSA) levels through the day. A similar, medium period northwest swell is expected to arrive late Thursday through Friday with a slightly larger reinforcing northwest swell arriving on its heels Friday. These swells will fill in through Saturday with another moderate size northwest swell arriving early next week. These series of northwest swells may push north and west facing shore surf back up to near HSA levels this weekend and early next week. The combination of this recent north swell wrap and shorter period trade wind wave swell will maintain choppy, slightly elevated east facing shore surf through tomorrow afternoon.
