Alright, let’s get into it. I’m lookin’ at Hakalau, and honestly, it’s a bit of a tough stretch ahead. This is a river mouth setup, exposed to the NE and ENE swells, and the water temp is sittin’ right around 80° with a slight warm anomaly of 2°, so it’s a touch warmer than average for this time of year – nothin’ too crazy, but nice if you’re in the water.
Right out of the gate, from Sunday the 5th of July all the way through to Wednesday the 15th of July, it’s just a run of poor surf conditions. Swell heights bounce between 4ft and 6ft, but the period is short – 7 to 8 seconds – so it’s weak and messy. The wind is mostly onshore or cross-onshore from the E, ENE, or NE at 9 to 12 mph, and that’s killing any chance of clean waves. The combined swell energy is moderate, mostly in the 294 to 495 range, but none of it is organized. There’s a solid 9 to 10-day gap here with no real recommendations – nothin’ worth paddlin’ out for.
Now, Thursday the 16th of July afternoon shows a flicker of hope. The swell bumps up to 7ft from the E at 8 seconds, and the energy jumps to 889 – that’s solid moderate energy, almost touchin’ strong. The wind goes light cross-onshore from the ESE at 6 mph, so it’s not all blown out, but the wave comment says marginal, and the score is a low 1. This is a peak in the forecast, but it’s still messy for a river break. The short period means it’ll be crumbly and hard to get a clean wall. Might be more interesting for the kite crowd than a paddle surfer, honestly.
Then Monday the 20th of July morning and afternoon is the closest thing to a standout. You’ve got 7ft from the ESE at 9 seconds, with light onshore winds from the ENE and E at 6 mph – that’s about as clean as it gets in this run. The combined energy is strong, 690 to 868, and the wind is light enough to keep things tidy. But it’s still only a marginal call, scores of 2 and 1. The swell is over 7ft, so it’s expert territory, and the period is still short – 9 seconds – so don’t expect long, drawn-out rides. With the ENE being the optimum direction for this spot, the E and ESE swells aren’t locking in perfectly, so it’ll be a bit wonky.
Overall, this is a long, quiet stretch for Hakalau. No true standouts, just a couple of days that might be worth a look if you’re desperate and experienced. The good news? There’s a pulse of energy toward the end, and conditions could change. Forecasts can shift.

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.
