The Lowdown
Alright folks, Rusty here, checking in on the Big Island waters. Let’s be straight with you – the next couple of weeks are looking flat as a pancake for a good surf. We’ve got a long wait ahead.
The most consistent option on the cards is Kawaihae Breakwater (Big Island). We’re looking at an almost two-week stretch of very minimal to no surf, starting Wednesday the 22nd of July. You’ll see a tiny bit of knee-high energy, around 0.7ft to 1ft, but it's so weak the combined energy barely gets out of the single or low double digits (like 55 on the 22nd). It’s just not worth paddling out for anything serious.
There is a glimmer of activity that shows up on the weekend of the 1st of August. The swell starts to show a little more life, coming from the West at 1ft to 2ft. The combined energy finally climbs into moderate territory, hitting 101 on the 2nd of August. When it does show up, it’s coming from the West which is the ideal direction for this spot. The wind looks clean with light to moderate offshore breezes from the NE and NNE. It’s not a standout by any stretch, but it’s the best we’ve got on the board. For a break that’s fairly consistent and can be crowded sometimes, this little window of surfable but very ordinary conditions is a better bet than the dead flat period before it.
After that, by the 3rd of August, it fades back into poor surf conditions with tiny swells again. Realistically, for the next two weeks, unless you’re desperate for a tiny wave and some clean conditions on the 1st and 2nd of August, you might be better off leaving the board in the car and enjoying the sunshine.
Rusty.

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

If you surf the same spot (Kawaihae Breakwater) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
