The Lowdown

Alright folks, Rusty here. Let’s have a look at what's on the menu at Hakalau over the next couple of weeks. It’s a bit of a mixed bag, to be honest, with some waiting involved.

Right off the bat, the first few days are pretty rough. Wednesday the 2nd is a write-off with rain showers and onshore wind making a mess of things. The combined swell energy is moderate at 977, but the surf is poor. Thursday and Friday offer some marginal conditions as a 7ft swell from the east rolls in with a long 14-second period, but the wind stays onshore. The energy picks up to a strong 1598 on Friday morning, but it's still messy.

The real standout window starts to shape up on Saturday the 5th. The morning is clean with light NE wind and a 7ft swell from the ENE, period at a solid 13 seconds. The combined energy is a very strong 1687. This is the best the forecast has to offer for a while – that’s proper river mouth juice. It’s a fairly consistent spot, but keep in mind crowds are possible here, especially with the weekend. The afternoon stays clean with light wind, and the swell bumps up to 8ft. Sunday the 6th keeps the good run going with 8-8ft ENE swell and glassy morning conditions. The energy is pumping in the 1700-1900 range. This stretch from Saturday morning through Sunday afternoon is your best bet for a proper session. The swell direction from ENE matches the optimum for the break, and the recent days of 3-5ft swell will have dropped off, so the river mouth should be handling the new groundswell better. The water temp is about average for the time of year.

After that, it gets ugly again. Monday the 7th through to the end of the first week is scrappy with strong cross-onshore winds and poor surf. There’s a long gap of no good recommendations for several days.

Then, a glimmer of hope. Sunday the 13th afternoon is something special. The wind goes glassy, and there’s a 6ft swell from the east. The combined energy is moderate at 318, but the glassy conditions make it a real treat. This is a sneaky good session for those who can wait. The period is short at 7 seconds, so the waves will be a bit weaker and more frequent, but glassy wind beats choppy any day.

Looking way out to Tuesday the 15th and Wednesday the 16th, there are some promising signals but far from certain. Tuesday afternoon sees a 6ft ESE swell with a long 13-second period and very strong energy (1628). Wednesday morning and afternoon pump with 8ft to 10ft swell from the E-ESE, energy in the 2200s. This is expert territory at over 8ft, but the trade wind cross-onshore breeze will spoil it. If that wind swings, it could be huge, but as it stands, the window is marginal.

Overall, lock in this coming Saturday and Sunday for the cleanest, most powerful swell. The Sunday the 13th glass-off is a hidden gem. The large swell in the second week is one to watch but don't book your flights yet.

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.
