The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s in store for the next couple of weeks.
The pattern is a bit of a mixed bag. We’ve got a solid pulse of swell pushing in right at the start, but the wind is going to be a constant battle, keeping the surf from really cleaning up. There’s a real chance of some decent waves on Monday the 27th and Tuesday the 28th, but you’ll be dealing with some chop. After that, the energy drops off and the wind gets nasty, leading to a long stretch of pretty poor conditions.
Hakalau (the only break on offer) kicks things off on Monday the 27th of July. The morning shows a solid 6ft of east swell with a 13-second period, carrying strong wave energy (1420). That’s a decent-sized groundswell, but the wind is blowing cross-on from the north at 6 mph, so it’s going to be a little bumpy. The afternoon picks up to 7ft with a 14-second period and even more energy (1813), but the wind swings to cross-on from the NNE at 9 mph, making it choppier. This is a river break, so longer period groundswell can actually work well here, but the wind is the main issue. Keep an eye on the tide, as it’s been flagged as questionable.
Tuesday the 28th of July is the best bet in the whole window, but it’s still compromised. The morning brings a solid 10ft of ENE swell, with a 12-second period and very strong energy (2859). That’s some serious size and power. For a river break, this could be a ripper, but the wind is a cross-shore from the NNW at 12 mph, creating a cross-chop. At 10ft, this is only for experienced surfers. The afternoon stays similar, with 10ft from the NE and still a cross-shore wind.
After that, the wheels fall off. Wednesday the 29th sees the swell drop to 5ft, but the period collapses to 8 seconds and the wind howls cross-on at 16 mph. The energy drops to a weak 387. This is a write-off, and it stays that way for days. From Thursday the 30th through the weekend, the surf is poor with onshore and cross-onshore winds, and the swell remains short-period and weak. This is a kite-surfing setup, not a paddle-surfing one.
The first week of August doesn’t offer much hope either. The wind finally goes onshore from the east, which is actually the optimum direction for this spot, but the swell is small and gutless. From the 1st to the 8th of August, wave heights wobble between 3ft and 7ft, but the period is mostly 7-8 seconds with weak energy. The water is about average for this time of year, nothing unusual.
The tail end of the forecast, around the 10th and 11th of August, sees a slight uptick in swell back to 6ft from the NE with a slightly longer period, but the wind is still not ideal. It’s looking pretty marginal all the way through. Overall, it’s a tough couple of weeks for Hakalau. The only real window is Monday and Tuesday at the start, and even then, it’s a battle with the wind.
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.
