The Lowdown
Alright folks, Rusty here. Time to talk about what’s on offer for the next couple of weeks. I’ve got to be straight with you – this is a tough one to write. The models are throwing up a proper bleak stretch, and there’s not a single day in the whole 16-day window that’s worth paddling out for. You’d be hard-pressed to find a worse run.
The problem starts early. From now right through to the 16th of August, the conditions are just plain ugly. The swell is onshore, mostly from the E or ESE, with a bit of ENE mixed in. The winds are either blowing straight on or cross-onshore, which means the surface is going to be a mess of chop and bumps. The wave comment on every single record is “poor surf conditions” or “marginal surf forecast or questionable tide conditions.” There’s no hiding it.
The only spot in the data is Hakalau, a river break. The swell direction is from ENE, which is the optimum for the spot, but it doesn’t matter because the wind is ruining it. The water temp is a warm 80°F with a 1°F anomaly, so about average for this time of year. The combined swell energy gets up to a moderate 958 early on Saturday the 1st, with a 8 ft ENE swell, but that's paired with a 12 mph onshore wind. That’s not surf, that’s a washing machine. The period is short too, around 8 seconds, so it’s just a weak, messy windswell.
The whole period is a write-off. There are no standouts, no hidden gems, nothing. This is a blank run. It’s not uncommon for the area to have quiet spells like this, but it’s frustrating. Forecasts can change, but for now, I’d put the board away and go do something else.
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.
