The Lowdown

Alright, let’s get real about it. Honestly, this is a rough 16-day run for Hakalau. We’re looking at a solid gap right off the bat, with nothing really worth paddling out for from now through to about the 22nd of August. The forecast shows almost nothing but “poor surf conditions” day after day. That’s a stretch of nearly ten days where you’re better off leaving the board in the truck.

Things don’t really start to look the least bit interesting until early on Sunday the 23rd. That morning we’re seeing some chest to head high swell coming from the ESE, running about 7 ft with a 9-second period. Combined swell energy hits 681 (moderate). The wind is light and cross-on from the east, so conditions will be a bit bumpy. The rating is still only marginal, but it’s the best on offer in the whole forecast.

Hakalau is a river mouth break on the Big Island, intermediate level, and it’s fairly consistent when there’s swell—but it can get busy. Expect crowds to be possible here. The optimum swell direction is from the ENE, and this ESE swell is a bit off that sweet spot, so don’t expect perfection.

After that brief window on the 23rd, it fades fast. Back into small, weak, and mostly junky surf through the end of August. Swell sizes drop to around 4 ft to 6 ft, periods stay short at 7 or 8 seconds, and energy values sink to 225–507 (weak to low moderate). Winds stay on or cross-on, so nothing cleans up.

If you’re a beginner, the swell on the 23rd is over 5 ft, so it might be a bit much. For anyone else, this is the only window worth looking at. The rest of the month is a write-off for real surfing. For the lake-like days with that tiny weak swell and onshore wind, a kite might be the better call than a paddle board.

This area just doesn’t get consistent surf in this pattern. It’s not unusual to see a long dry spell like this.

There’s no standout session here. The early morning on Sunday the 23rd of August is as good as it gets, and that’s not saying much.

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.
