The Lowdown

Alright folks, Rusty here. Let’s get straight into it. The outlook for this stretch is a bit of a bummer, if I’m being honest. We’ve got a solid gap of poor conditions right through the next couple of weeks. There’s nothing on the cards for the first few days, and the pattern gets stuck in a rut of onshore breeze and messy surf.

The first real shot at anything comes on Sunday 2nd August, but it’s a real marginal one. Hakalau, a river mouth set-up, will see a 7 ft swell from the ENE, but the wind is blowing onshore from the E at 12 mph. It’s a “marginal” call at best, and the combined swell energy is a moderate 770, so there’s push there, but it’s not clean. The period is a short 8 seconds, so it’ll be a bit of a close-out mess. This one is really for the keen locals only.

Honestly, the standout window, if you can call it that, is a narrow one on Monday 3rd August. The swell drops to 5 ft ENE, but the wind turns light from the ESE at 6 mph, which is a cross-on breeze. The energy drops to 466 (moderate), but the period sneaks up to 9 seconds. It’s still a “marginal” forecast, but it’s the best the weekend has to offer. The water temp is about 80°, which is normal for the time of year. This is a river mouth, so with a longer 9-second period, it might just offer a few workable walls. But honestly, don’t get your hopes up.

After that, from Tuesday 4th August all the way through to Saturday 15th August, the forecast is a long, grey stretch of “poor surf conditions” and “marginal” calls. The wind is stuck cross-onshore from the ESE or E, mostly around 9-12 mph, keeping everything choppy and ugly. The swell energy stays between 199 and 437 (weak to moderate), and the period rarely gets above 8 seconds. There’s a slight bump in energy on Wednesday 12th August morning with a 6 ft ENE swell and 782 energy, but again, the wind is cross-onshore at 9-12 mph, making it a mess. This is more of a kite-surfing setup than a clean paddle session.

The only break on the list is Hakalau, and it’s a river mouth that’s “fairly consistent” but this time of year it’s just not getting the right wind. The crowds are “sometimes” an issue, but with this forecast, I doubt you’ll see many. I’d say save your energy. The forecasts can change, but this run looks determined to stay poor.

Stay patient, folks. Rusty.

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.
