The Lowdown

Alright, this is Rusty. Let's talk about what's on the menu for the next couple of weeks.

Alright, listen up. The next 16 days are looking like a bit of a mixed bag for Hakalau. We've got a solid stretch of nothing happening right off the bat, through Tuesday the 22nd and into Thursday the 24th. The wind is mostly cross-on or onshore, and the surf is just plain poor. No point in paddling out for that. Things start to get a little interesting, but not great, around Saturday the 25th. You'll see a bit of a pulse on Saturday afternoon with a clean 2ft of swell, but it's a super long 16-second period from the E. That kind of period is a groundswell, and it can be a bit tricky at a river mouth setup like this.

The real standout, the one that's got my attention, is the stretch from Sunday the 26th through Wednesday the 29th. The swell is building, and the water's getting some energy. It's not perfect, but it's the best we've got. Let's break it down.

Sunday the 26th is the first real call. The morning sees a 6ft swell from the E, with a 16-second period. The combined energy is climbing into the strong range (1645). It's a bit on the bigger side, but for an intermediate, it's worth a look. The wind is onshore from the NE, but it's light. That long period will be the key – it'll be straight and powerful at the river mouth, so pick your takeoff spot carefully.

If you can wait, Tuesday the 28th is the best of the bunch. The morning has a 6ft swell from the ENE with a 13-second period. The combined energy is still strong (1224). The best part? The wind is a light cross-shore from the N. That's going to clean it right up. The swell is getting up there, pushing 7ft in the afternoon, so it's probably for experienced surfers only. The water temperature is about 80°, which is totally normal for this time of year.

Wednesday the 29th is very similar, with a 7ft swell from the ENE and a 12-second period. The wind is a light cross-onshore, not quite as clean as Tuesday morning, but still manageable. The combined energy is strong (1224).

After that, it all fades out. The wind picks up from the 30th of July, and we're back to poor surf and choppy conditions. There's a tiny flicker around the 2nd and 3rd of August, with a small 5ft groundswell on the 2nd, but it's a short 8-second period, so it's not going to be worth much. The 3rd of August has a 4ft, 15-second swell from the E, which is a long-period groundswell again, but it's small. The combined energy is moderate (1075). It's a "maybe" at best, but far from the quality of that late July window.

Overall, keep your eyes on the 26th through the 29th of July. Tuesday the 28th morning is your best bet for clean, solid waves. The rest of the time, you're better off waiting for the next proper swell.

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.
