The Lowdown
Alright folks, Rusty here again, switching over to feet and Fahrenheit for the mainlanders. Let’s look at Hakalau over the next sixteen days.
Right out of the gate, it’s a tough scene. From Thursday the 6th through most of the following week, we’re dealing with onshore and cross-onshore winds from the east. The swell is tiny and weak for the first week – energy readings start at just 181 (weak), and even when they climb a bit, it’s still poor quality. The water is about 80°, which is normal for this time of year. Nothing to write home about.
You’ve got a real dry spell here. From the 6th all the way to around the 14th, there’s nothing worth a paddle. A few marginal sessions pop up, like Saturday morning the 8th with a 4ft swell from the ESE, but the wind is still on it, so it’s a no go. It’s a blank run – plain and simple.
Then, patience might pay off. Starting Saturday the 15th, the swell starts ramping up. The real standout hits on Tuesday the 18th. That morning you’re seeing an 8ft swell from the ENE with strong energy at 1697 (very strong). The wind is cross-onshore at 15 km/h, so it’s not perfect, but the afternoon is where it gets serious. The swell jumps to 8ft with a period of 11 seconds – that’s long period groundswell – and the combined energy skyrockets to 2405 (very strong). The direction is dead on the optimum for this spot, ENE.
Now, at 8ft, this is big wave territory – experts only. That long period (11 seconds) means it’s got serious punch, and because it’s a river mouth break, it might bend in nicely if the tide is right. The downside is the wind is onshore, though it’s a light breeze at 15 km/h, so it could be cleaner than you’d expect. It’s a shame it’s not glassy, because this could have been a proper bomb. But if you’ve got the skills, Tuesday the 18th is your only real shot in this whole sixteen-day stretch. Otherwise, it’s a long wait.
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.
