The Lowdown
Alright, crew, Rusty here. Let’s talk Hakalau.
The first two weeks are a write-off. From today, the 14th of July, through to the 24th of July, there’s a solid ten-day stretch of nothing. The wind’s mostly cross-onshore, the swell is short-period and weak, and you’ll just be paddling through chop. Save your energy.
The water’s 80°, which is normal for this time of year, so no surprises there.
The window opens on the 25th of July. Saturday the 25th sees a very long-period groundswell kick in, with the period hitting 14 seconds and then 16 seconds. The energy is moderate (608) in the afternoon. The swell is tiny, just 2ft, but it’s clean with light, onshore breeze (ENE 10 mph). The real standout is Sunday the 26th of July. The swell builds to 5ft from the East, with a super-long 16-second period and energy readings over 1300 (strong). The wind is light and onshore (ENE 15 mph), so it’ll be glassy. That’s the best surf of the run. It’s a river break, so a long-period groundswell like this can really focus the waves.
Monday the 27th pushes up to 6ft, but the wind goes cross-onshore, bringing in some chop. The energy is still very strong (1588), so there’s power, but it won’t be as clean as Sunday. Tuesday the 28th of July is the biggest, with 8ft swell from the ENE and a 13-second period. That’s serious size, with energy hitting 2296. It’s for experts only, and the light onshore breeze will keep it from being perfect. Wednesday the 29th drops to 8ft, still with strong energy, but rain and a cross-onshore wind will mess it up a bit.
Bottom line: circle Sunday the 26th of July. Clean, 5ft, glassy, and a proper long-period groundswell. Worth the 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.
