The Lowdown

Alright, folks, Rusty here. Let’s check out what’s happening at Kawaihae Breakwater over the next couple of weeks.

Right off the bat, it’s pretty flat and quiet. From Wednesday, the 29th of July, right through the first week of August, there’s basically nothing doing. We’ve got a solid week-long gap with no real surf on offer. The water temperature is sitting at about 80°, which is pretty normal for this time of year, so no worries there if you just want a swim.

That first real pulse of energy finally shows up on Friday morning, the 7th of August. We’re looking at small, weak waves, only about 2ft from the west, with a moderate combined swell energy of about 168. The wind is light offshore from the NE, so the surface will be clean, but it’s still just "surfable but very ordinary." This is more of a warm-up day.

The standout window, the best we’ve got, kicks off on Monday morning, the 10th of August. Expect solid 3ft west-northwest swell with a combined energy jumping to a much more interesting 295. The wind is light offshore, almost glassy, so it’s going to be clean and lined up. This west-northwest direction is a good fit for Kawaihae's optimum W direction, and with the moderate energy, it should have some nice shape. This is your pick.

Then heading into Tuesday and Wednesday, the 11th and 12th, the swell holds in the 2-3ft range, with glassy conditions. On Tuesday afternoon, the energy spikes to 321, and the wind goes light offshore again. That late Tuesday session looks sweet, with good, clean waves. The following Thursday morning, the 13th of August, also looks promising with a 2-3ft west-northwest swell and clean conditions.

So, to be straight with you: it’s a slow start, but there are a few really clean, fun windows in the second week. The 10th through the 13th of August is where you want to be in the water. It won't be huge, but the conditions are set up just right.

Rusty.

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.
