The Lowdown

Alright folks, it’s Rusty here. Let’s be straight with you. Looking at the next couple of weeks, this is a rough patch. We’ve only got the one spot on the list, Hakalau, and it's a river mouth that’s fairly consistent, but it’s going to be battling the wind for almost the entire run. Water temp is pretty normal for this time of year, nothing crazy, just the usual warm stuff.

The first call is Sunday morning, August 2nd. There’s some swell showing at 7ft from the ENE, with a period of 8 seconds. The energy is moderate at 770. It’s not huge, but it's on the way. However, the wind is on from the ENE at 9 mph, and that’s going to mess things up. This is a river break, and with that east wind, it’s going to be bumpy. It’s a marginal call at best. The afternoon drops slightly to 6ft but the wind stays on, so it’s not looking any better.

Monday the 3rd is a bit smaller, 5ft from the ENE with a light cross-on breeze. The swell period stretches to 9 seconds in the afternoon, but we’re still looking at poor surf. The wind is just not helping; it’s constantly putting a texture on the face. This is not the day to get fired up about.

Tuesday through Thursday, the 4th to the 6th, are pretty grim. The swell drops and the cross-onshore wind stays, making everything look rough. The energy weakens from 471 down to 125. Honestly, it’s a write-off. You’d be better off finding something else to do. It’s a real dry spell.

The brief bump on the 8th of August, Saturday morning, sees the swell jump back to 5ft with a period of 7 seconds, but it’s still with an onshore wind. The energy is up to 562, but the short period and wind will make it a close-out mess. The week that follows, from the 9th to the 15th, is a real grind. It’s all poor conditions with moderate cross-onshore winds and rain showers. There’s some size, mainly in the 4ft to 6ft range, but it’s all junky. This isn't good for paddling, and honestly, with the wind and chop, this spot looks more like a kiteboarding zone than a surf spot.

Now, looking further out, things get a little interesting but we can’t get too worked up. On Monday the 17th of August, the energy jumps to a strong 1259 by the afternoon, with 7ft of ENE swell. The period is still short at 8 seconds, and the wind stays cross-on, but that energy is undeniable. There’s a slight chance it cleans up a little, but it’s still a long ways off. The forecast for the first week is solid – and it's bad. The second week is less certain, but this late bump might be our only real shot, even if it’s a messy one. The only window with any real power, and it's still a gamble.

Stay tuned, but for now, keep the board in the car and the expectations low. It’s a waiting game.

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.
