Hawaii North Shore forecast by Craig Brokensha (issued Thursday 17th December)

Best Days: Every day over the coming period

This week and next week (Dec 17 - 25)

Yesterday morning started slow and small, but a mix of new NW groundswells filled in through the day, offering some good size into the evening.

Today a peak in size is being seen across the North Shore with pumping 6-8ft surf for the Pipe Masters.

The 51101 buoy situated about 500km north-west of the North Shore has since eased from a peak early this morning Hawaii time, and with a buffer of around 10 hours, we should see the swell ease later today and then further down through tomorrow from 5-6ft on the sets. Friday will be even smaller with fading 3ft+ waves.

Gusty and sometimes strong E/NE trades are due tomorrow, picking up later Friday and persisting most of the weekend, bringing with it some small to moderate sized E'ly trade-swell.

A small and inconsistent long-period NW groundswell is due early-mid next week from a very intense low forming right on the Aleutian Islands tomorrow. A slither of severe-gale W/NW winds will be generated in Hawaii's swell window, producing an inconsistent NW groundswell for Monday, building to 3ft through Monday, persisting Tuesday and Wednesday as the trades start to weaken.

Longer term some slightly better and moderate sized NW groundswell are due Thursday and then the following weekend from a stalling and multi-staged low south-east of the Kamchatka Peninsula.

We're looking at pulses in the 6ft to possibly 8ft range but we'll have a closer look at this on Tuesday.
