The Lowdown
Alright folks, Rusty here. Let's get stuck into the next 16 days for this little corner of the world.
Right off the bat, it's not looking like a classic stretch. The surf is on the table, but it's going to be a grind. The wind is a major pain for most of the opening week, and we're dealing with a lot of "marginal" days. The water temp is sitting at 81°F, which is pretty much bang on average for this time of year, so no surprises there.
Hakalau is the only spot on the cards. The swell direction is mostly out of the ENE, which is what the spot wants to see, but the wind is a constant issue. The first few days from Thursday the 3rd right through to the start of the following week are a write-off – mostly cross-onshore wind making a mess of things. The combined swell energy is moderate (743) on Thursday morning, but it doesn't matter when the wind is junk.
Friday morning the 4th sees a bit more size, with 7ft of ENE swell, but the 14-second period gives it some push. The energy jumps up (1784), but it's still cross-on. The weekend is a similar story – Saturday the 5th has 7ft to 8ft swell with a 13-14 second period and light wind, but it's still a cross-on. The real issue is the quality. These are all marked as marginal, which means the tide or the texture is just off.
The best chance to actually get a clean one looks like it comes in the second week. Monday the 14th and Tuesday the 15th are a wash – the wind swings onshore and the period drops to 8 seconds, making it short-period, choppy junk. Not worth it.
The standout window is Wednesday the 16th and into Thursday the 17th. On Wednesday, we've got 7ft of swell from the ESE with a 12-second period and a light onshore wind that's actually just "on" – light and straight. The energy is strong (1442). The afternoon gets even better: 6ft of swell, still 12 seconds, and the wind drops to near glassy (5 km/h). That's the cleanest the window gets. It's a marginal call, but with that glassy wind, it's the one to aim for. The swell is a bit much for beginners, but for intermediate and above, that's a session.
The 12-second period is a solid groundswell, which means the waves will have some shape, but at a river break like this, it can sometimes be a bit straight. Still, with the wind that light, it's the best we've got.
Honestly, for the first week and a half, it's a battle. The setup is more interesting for kite surfing than paddle surfing on those cross-wind days. The wind is just too messy. Hold out for that Wednesday the 16th. That's the one.
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.
