The Lowdown
Alright, Rusty here again, looking at the same stretch for Hakalau. It’s a rough couple of weeks, no two ways about it. Most of the time, the wind is onshore or cross-onshore, and the surf quality is just poor.
We get a little something on Monday afternoon, August 3rd. There’s a 4ft swell from the ENE, with a 9-second period, and a light breeze from the east at 6 mph. The water is 80°, which is about normal. The combined energy is moderate at 434. It’s just a marginal start.
Tuesday morning, August 4th, shows a 5ft groundswell from the ENE, with a longer 11-second period. That’s better energy, but the wind is cross-onshore, so the surf is still called poor. The energy is moderate at 490.
Then it’s a long, painful gap. From Wednesday, August 5th, all the way through the second week, it’s a mess – cross-onshore winds, lumpy conditions, and swell heights staying under 5ft with short periods. There’s a spike on Sunday, August 9th, with a 7ft east swell, but it’s got a short 8-second period, a risk of thunderstorms, and moderate cross-onshore winds. The energy is moderate at 528, but the conditions are poor – that’s kite-surfing weather, not for a paddle.
The only slightly better window pops up on Saturday, August 15th, and Sunday, August 16th. We get a 6ft swell from the ENE, an 8-second period, and a light breeze from the east at 9 mph, going onshore. The energy is moderate at 461. It’s not clean, but it’s the least messy day in the whole outlook. For a spot that’s usually fairly consistent, this is a proper dry spell. You’ll be waiting for the next system to change things up.
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.
