Table - best surf conditions forecast for Kawaihae Breakwater over the next 16 days.
Alright, folks. Rusty here, checking in on the Kawaihae Breakwater outlook for the next couple of weeks.
We’ve got a slow start – the first few days are basically flat and not worth a paddle. The wait begins. By Sunday the 12th, we start seeing some tiny, rideable waves, but it’s still pretty ordinary. The real action picks up on Tuesday the 14th when a better swell starts to fill in. The water’s a touch warmer than average for this time of year, sittin’ around 80°F.
The standout window is Wednesday the 15th. That’s your day. We’re looking at a clean 3ft groundswell out of the W, with a period of 16 seconds – that’s some long-period juice that’ll set up nicely on this reef. The combined energy is solid at 353 (moderate wave energy), and the wind is looking glassy in the morning with a NNE breeze at just 3 mph. That’s about as perfect as it gets around here. The swell direction is straight from the optimum W direction, so the break should be firing. It’s fine for intermediates, but keep in mind it can get crowded sometimes, so plan to beat the rush.
The swell holds up into Thursday the 16th morning with 3ft from the W and clean conditions, but it fades in the afternoon. After that, the second week dries up fast. From the 19th onward, it’s back to tiny, poor surf, with a long flat spell running through to the 24th.
Bottom line: the first half is a grind, but Wednesday the 15th is the real gem. Don’t miss it.
Rusty.

A general guide to surfing at Kawaihae Breakwater can be found by selecting the local surf guide option on the grey menu.

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.
