The Lowdown

Alright, Rusty here again with the imperial take.

Well, we’re looking at a pretty bleak sixteen days at Hakalau. This river mouth break needs ENE swell to work, and while we get some size, the wind is just brutal. For the first week, it's all cross-onshore ESE wind. The water temp is about what you'd expect for this time of year, nothing wild. The combined wave energy starts at 342 and climbs into the 800s and 900s, so there’s plenty of water moving, but with a short period of 8 seconds and that onshore wind, it’s just a choppy, messy mess. There’s no surfable quality through the end of July and into the first few days of August. The wind does turn onshore on the afternoon of the 31st of July, but the condition is still poor. The energy hits as high as 976 on the afternoon of the 1st of August, but it’s meaningless with the wind and period. Not worth getting wet.

The only real window to consider is the 3rd of August. The morning shows swell from ENE at about 5ft with a 9-second period and a light onshore breeze. The energy is 551. It's still just marginal. The afternoon gets interesting: the period jumps to 13 seconds, a real groundswell, but the height drops to 3ft. Energy is 640. That long period could make it break a little too straight for a river mouth, but the light onshore breeze might keep the surface clean. It’s a long shot, but that’s your best option. After that, it’s back to poor conditions with cross-onshore wind and low energy all the way through to the 13th of August.

On the 13th of August morning, the energy climbs back to 815 from the ESE at 6ft, but the wind is still a moderate cross-onshore. It’s a poor call.

There’s no true standout session here. If you’re desperate, aim for the 3rd of August afternoon for a small, clean, long-period wave. For the rest, it's a dust-off. This kind of run is pretty normal here. The onshore trade winds don't let up often. Keep an eye on the forecast, but for now, it's a no-go.

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.
