The Lowdown

Alright folks, Rusty here. Let’s take a hard look at what’s coming down the pipe for the next couple of weeks.

To be straight with you, this isn’t shaping up to be a classic run. We’re looking at a stretch of mostly cross-onshore or onshore wind, and the wave quality is going to suffer for it. There’s no standout session in the first week that I’d tell you to drop everything for. The wind is just too messy.

We have a window starting around Thursday, August 14th where the swell picks up a bit. On Friday morning the 15th, Hakalau is seeing a 7ft swell from the East with a 9-second period and moderate energy (700). The wind is cross-onshore though, so it’s going to be fairly choppy. That’s about as good as it gets in the first week, and it’s only a marginal call at best.

Then things get bigger but uglier. Saturday the 16th has a solid 12ft to 13ft ENE groundswell (very strong energy up to 4479), but with heavy rain and a strong cross-onshore wind, that’s a big, lumpy mess. That’s strictly for experts and even then, it’s not going to be pretty. Sunday the 17th is still big at 12ft from the ENE with a 10-second period, but the wind is cross-shore and messy.

We essentially have a dead run through the middle of the period. The wind stays onshore or cross-onshore right through to Monday, August 25th.

Now, here’s the one that catches my eye, but it’s a long way off. On Monday morning, August 25th, the swell ticks up to 8ft from the ESE, with a 9-second period and strong energy (1671). The wind is still a gentle cross-onshore, so it's not perfect, but it’s the best looking size and energy combo in the whole forecast. It’s the only day with a score that hints at something worth looking at. Keep an eye on that one, but remember it’s a long-range call and the wind could easily swing the wrong way.

For the rest of the run, it's small, choppy, and onshore. Not much to get excited about until that late surge around the 25th.

Water temp is sitting at 80°F, which is about average for this time of year. The anomaly is only 1°F, so nothing weird going on.

Stay tuned, but for now, I’d be looking at other plans.

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.
