Alright folks, Rusty here. Let’s have a look at what’s on the table for the next couple of weeks at Hakalau.

Right off the bat, I gotta be straight with you – it’s a tough run. We’re looking at a solid 16-day window, but honestly, there’s no proper stand-out session in there. The whole stretch is plagued by onshore or cross-onshore wind, mostly blowing straight out of the east, which is about the worst direction for this setup. That onshore wind is just shredding the surface, making everything a choppy mess.

We’re starting Sunday, July 12th, with some rain showers and a 12 mph easterly wind. The swell is hanging around 6 ft, from the east, but with a short period of only 8 seconds. The combined energy is moderate, coming in at 979, but with that wind, it’s gonna be a messy, blown-out wall. Not what we want.

This trend doesn’t let up. Through Monday and into Tuesday, the swell drops a bit, but the wind stays on it from the east. The water is about average for this time of year, nothing unusual there.

Wednesday the 15th through Friday the 17th see the wind pick up again, with moderate breezes around 12-15 mph from the ESE. The wave heights are knee-to-waist high max, and the period is a short, weak 7 seconds. The energy drops significantly into the low-to-mid hundreds (168 to 162). This is not surf for a paddle board; the setup looks more interesting for kite surfing than paddle surfing with this constant onshore wind.

We get a little bump in size around Saturday, July 18th, into Sunday the 19th, with waves pushing 5 ft to 6 ft from the east. The period is still short (8 seconds), and the wind is still on it, so again, the quality is just not there. It’s waves, but not surfable waves worth paddling out for.

Then, heading into the second week, from July 20th, there’s a real lull. The swell gets small, between 2 ft and 4 ft, with even weaker north-easterly energy. The only glimmer is that the period briefly jumps to 15 seconds on the 20th, but that’s a groundswell and a long period, which can break too straight and close out at a river mouth like Hakalau. It’s also paired with a still-poor wind.

From July 21st right through to the 27th, it’s just small, short-period slop. The wind never truly drops to that magical offshore. Hakalau is a fairly consistent spot, so a blank run like this is a bit of a rough patch, but not unheard of. The forecasts can change, but as it stands, save your energy.

For the whole 16 days, there is no standout session.

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.
