The Lowdown
Alright, folks, Rusty here. Let’s talk about the next couple of weeks. I’ve got to be straight with you – the surf window we’re looking at is pretty bleak. We’ve got a long stretch of small, messy waves and onshore winds. If you’re desperate for a paddle, you’ll find something, but you’ll be working for it.
The first few days, through August 4th, we’ll see some chest to head-high swell around Hakalau (Big Island). It’s coming from the ENE, but the energy is only moderate, around 886 at the start. The wind is mostly light onshore, which is going to keep things a bit bumpy. The water’s a touch warmer than usual for this time of year, about 1°F above average, but that’s the only thing that’s slightly special.
The real problem is that after Tuesday, the swell just fades away. From the 5th through the 13th, we’re looking at a whole lot of nothing. The wave heights drop to below 3 ft, the energy weakens to two-digit and low three-digit numbers. Even when we get a small pulse, the period is short, and the wind is mostly cross-onshore from the ESE, chopping everything up. It’s a solid week of poor conditions. Not really worth your time unless you’re just keen to get wet.
Things get a little more interesting by the 16th, which is a Saturday. We’ve got a push of swell coming in, up to 7 ft, with energy climbing back to 625. It’s still from the ENE with a moderate period, but this is the most promising looking wave of the entire run. The catch is the wind is still cross-onshore, so it won’t be clean perfection. But it’s the only day in the whole window where I’d say it’s worth checking the buoys and taking a look. It might be a bit too much for beginners, but it could be fun for the crew.
Don’t get too excited about the long-range stuff, though. It’s promising, but it’s a week and a half away, so things can change. Until then, it’s vibes and patience.

Information about the Hakalau Surf forecast
The above surf forecast table for Hakalau provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Hakalau can be found by selecting the local surf guide option on the grey menu. Our Hakalau 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. If you surf the same spot (Hakalau) 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 Hakalau 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.
Hakalau is 21 km (13 miles) from Hilo. If you plan a vacation in Big Island, look for hotels and other accommodation in Hilo. Hilo has rooms for a wide range of budgets as well as car hire and transport links.
