The Lowdown

Alright, let’s break it down. For the next 16 days, things are lookin’ real flat around here. We’ve got one spot that’s barely kickin’ a few times, but most of the time it’s poor or dead. No big standouts, just a couple of tiny windows to get a few rides.

The only break in the game is Kawaihae Breakwater (Big Island). Water temp is 81°, which is normal for the season, so no surprises there.

We kick off Saturday the 22nd with tiny 1ft to 1ft swell from the SW. The wind is light offshore from the NNE-NE, keepin’ it clean. The combined energy is weak, only 70 to 120, so the waves are small and weak. You can surf ‘em, but it’s nothin’ to write home about.

Sunday the 23rd is the same story – 1ft to 2ft from the WNW, period around 11 seconds, so a little more push but still tiny. Winds stay offshore, clean. If you’re on a longboard you might get a couple, but it’s barely worth it.

Then it’s a long dry spell. From Monday the 24th all the way to Saturday the 5th of September, it’s mostly poor conditions with swells droppin’ to 0.3ft, 0.6ft, or flat. A brief window on Thursday the 3rd and Friday the 4th shows 1ft from the west with glassy winds, but the energy is still weak (under 40). Nothin’ to get out of bed for.

Finally, on Sunday the 6th of September, we get a slight bump. Lookin’ at 1ft swells from the SW and then WNW, with a very long period of 18 to 19 seconds. The combined energy hits 103 and 147, so that’s the most wave energy we’ll see. Winds are glassy. That long period means the waves will have some shape, but at a reef break like this, those long gaps between sets might make it feel even smaller. Still, for a spot that’s been flat for nearly two weeks, Sunday the 6th is your best bet. It’s not a standout, but it’s the only day I’d bother checkin’.

Overall, it’s a grim forecast. The first weekend (22nd-23rd) or that Sunday the 6th are your only real chances. Otherwise, the boards are stayin’ dry.

Information about the Kawaihae Breakwater Surf forecast

The above surf forecast table for Kawaihae Breakwater provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kawaihae Breakwater can be found by selecting the local surf guide option on the grey menu. Our Kawaihae Breakwater surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Kawaihae Breakwater may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
