Alright folks, let’s break down what’s happening at Hakalau over these next couple of weeks. To be straight with you, it’s a long, dry spell.

We kick off Monday 6th July, and it’s not good. Onshore and cross-onshore winds from the NE and E, blowing 9 to 12 mph, are making a mess of things. The swell is running 4 to 6 feet, but it’s short-period wind swell (7-8 seconds), so it’s all bump and no grunt. The combined energy readings are moderate, but that doesn't help when the wind is chopping everything up.

This ugly pattern just keeps rolling through most of the first week and into the second. Day after day of "poor surf conditions" and "marginal" reports. The water temp is normal for this time of year, around 80°, but that’s small comfort.

The one little window that might be worth a look is Thursday morning 16th July. The wind is forecast to go glassy, and the swell will be a small 4 feet from the east with an 8-second period and a weak combined energy reading. It’ll be clean, but small. After that, it’s back to choppy, cross-on winds.

Then on Monday 20th July, we see a weird jump in period – an 18-second groundswell from the east. The energy jumps up high to 956 (strong), but the wave height is tiny at 3 to 4 feet. On a river mouth like Hakalau, those long-period waves (over 15 seconds) tend to straighten out, so don’t expect much shape.

Honestly, it’s a tough outlook. The only tiny glimmer is that Thursday 16th July morning. Everything else is a blown-out mess. Might be a good time to work on your tan or check the tide pools.

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.
