The Lowdown
G’day, Rusty here. Look, I’ll level with you – the next 16 days at Hakalau are a bit of a mixed bag, and we’re not talking about a classic run of form. The early part of the outlook is pretty grim, with a lot of onshore wind and messy conditions. We’ve got a gap of almost no surf worth mentioning from now until the end of July, with only marginal scores. The real standout, and it’s a decent one, comes in the second week, but let’s walk through it.
Starting off, Friday the 24th of July, we’ve got rain showers and an onshore wind from the east at 12 mph, with a 5.2 ft swell from the east-northeast, but the period’s a short 7 seconds, and the combined energy is weak (346). It’s just poor surf conditions. Saturday the 25th is similar – a morning of onshore wind and marginal surf, with a 4.9 ft swell from the east, still only 8 seconds. The afternoon gets a bit better with some clouds, but still onshore wind and a 4.3 ft swell from the north-northeast. Nothing to get excited about.
Sunday the 26th of July offers a little more hope. A clear morning with onshore wind, but look at that swell: 3.9 ft from the east, but the period jumps to 14 seconds – that’s a long-period groundswell. The combined energy is moderate (857). The wind is still onshore, though, so it’s not clean. The afternoon is similar, with a 4.3 ft swell from the east and a 15-second period (981 energy). It’s still marginal, but that long period means real energy in the water. Hakalau is a river mouth, so a long-period groundswell can break straight, but it’s the only thing offering a pulse.
Monday the 27th of July is the first time we see a cross-on breeze, with a 6.2 ft to 6.6 ft swell from the east, 13 seconds, and the combined energy jumps to strong (1398–1574). The wind is light from the north-northeast in the morning, then a gentle breeze from the north. This is where it gets interesting – the swell is building, but it’s also getting bigger. Over 5 ft, it’s not for beginners, and at 6.6 ft, it’s getting solid. The cross-on wind means it’ll be a bit bumpy, but there’s push.
Now, Tuesday the 28th of July is where things get serious. A risk of thunderstorms, a 11.5 ft swell from the east-northeast in the morning, 13 seconds, and massive combined energy of 3959 – that’s very strong. Wind is a moderate cross-shore from the north-northwest at 12 mph. This is big, powerful surf. At 11.5 ft, it’s expert-only territory. The afternoon drops to 9.8 ft with 12 seconds, still huge. This is the standout for the first week, but only for experienced surfers who can handle heavy, cross-shore chop.
After that, the swell drops off. From Wednesday the 29th of July through to the end of the month, we’re back to poor surf conditions with onshore and cross-on winds, swell under 6.6 ft, and short periods. There’s a bit of a pulse on the 31st of July with a 6.2 ft east swell and 8 seconds, but the wind is onshore, and the energy is only moderate (731). Not worth it.
Then we hit a gap. From Saturday the 1st of August through to Tuesday the 5th, the surf is marginal at best. The 1st of August morning has a 5.6 ft swell from the east-northeast, 8 seconds, and onshore wind – not great. The afternoon sees a 3.3 ft swell from the east with a 14-second period, but again, onshore wind. The energy is moderate (740). Sunday the 2nd of August brings a 3.9 ft to 4.3 ft swell from the east, with a very long 17-second period, and onshore wind. The combined

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.
