The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming for the next couple of weeks.
Right, quiet is the word to start. There isn’t much happening right now, and we’re going to have a chunk of days where it’s just not worth paddling out. The first proper look we get doesn’t arrive until Sunday the 27th, so we’re in a bit of a lull before that.
Things do pick up for a window from Monday the 28th through Tuesday the 29th. That’s where the main action sits. The water at Hakalau is sitting at 80°F, which is about average for this time of year, nothing weird going on there.
The standout of the whole window has got to be Monday the 28th, morning session at Hakalau (Big Island). You’re looking at a clean 6ft of easterly groundswell, with a solid 13-second period – that’s proper energy, and it’s coming right from the east-northeast, which is the optimum for this spot. The combined energy is pumping at 1448 (moderate). The big deal here is the wind: it’s a light northerly breeze, just a cross-shore, keeping things clean. It’s a bit big for beginners at that size, but for anyone intermediate and up, this is your window. Keep an eye on the crowds though, it can get busy there sometimes.
Tuesday the 29th morning jumps up a notch in size to 10ft from the east-northeast, still with a long 13-second period. The combined energy is huge at 3333 (strong). That’s a serious number. But that pushes it into expert-only territory. The wind is a moderate cross-shore from the north, so there’s a bit of cross-chop on it. Not as clean as Monday, but if you’ve got the skills and the board for it, it’ll be powerful.
After Tuesday afternoon, the swell backs right off. From Wednesday the 30th all the way through to Monday the 10th of August, it’s a long, drawn-out stretch of weak, short-period windswell with messy onshore winds. The energy drops to three figures (down to 115 at the lowest). The period drops to 8 seconds or less, and with the cross-onshore breeze, it’s mostly choppy and poor. The waves on offer are small and weak, under 5ft, and the quality is shot. Honestly, with that persistent wind and poor shape, the setup at this beach looks more interesting for kite surfing than paddle surfing for most of that second week.
There is a small glimmer on Monday the 10th of August morning, with a tiny 3ft from the northeast, but the period is a short 7 seconds and the energy is weak at 212. It’s just not enough to get excited about. We’ll have to wait and see if the forecasts change, because right now, the first couple of days and then that long gap from the end of July into August are pretty lean.
Stay patient, get that Monday the 28th if you can.
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.
