The Lowdown

Alright, Rusty here. Let's get into it.

Right off the bat, this 16-day window for the Hakalau area looks pretty grim. We're starting on Friday, September 4th, and there's really nothing good to chase. The swell is there, but the wind is messy and the conditions are just not lining up. A real "wait and see" kind of stretch.

First up, Friday, September 4th:
We’ve got some solid energy coming in – a combined swell energy of (1957) is pumping, with a 7 ft swell from the east at a long 14-second period. That's plenty of water. But the wind is a cross-onshore from the east at 9 mph, and it's described as "gentle cross-onshore and fairly choppy." The morning gets a rating of 1/10, and the afternoon bumps up to a 3/10, but the "marginal surf forecast or questionable tide conditions" keeps it from being any fun. This is not the day to paddle out at Hakalau (United States). The water temp is about average for this time of year, so no surprises there.

Saturday, September 5th:
Pretty much the same story. A 7 ft to 8 ft east-northeast swell with a 13-second period and a combined energy of (1686) and (1810). The wind is still a cross-onshore easterly at 6 to 9 mph. It's just choppy and messy. Scores of 2/10. This setup looks more interesting for kite surfing than paddle surfing.

Sunday, September 6th to Monday, September 7th:
The swell dips slightly, and the wind picks up. Sunday sees a cross-onshore ESE breeze at 9 to 12 mph (moderate breeze, choppy). Monday is worse, with a stronger cross-onshore SE wind at 16 mph and "poor surf conditions." Scores drop to zero. The 7 ft to 7 ft swell from ENE is out of the question.

Tuesday, September 8th onwards:
The swell drops right off to 3 ft on Tuesday and Wednesday, with combined energy dropping to (599) and then (437). Still cross-onshore or onshore winds. The window stays completely flat or poor until about Friday, September 11th, when we see a small pulse come in at 5 ft from the ENE, but it's still a "poor surf conditions" call on the morning, and "marginal" in the afternoon (1/10). There’s a long gap here of about four days with absolutely nothing worth mentioning.

The Second Week (from around September 14th):
The swell tries to build again a bit, with 8 ft on Monday, September 14th, and combined energy hitting (1051). Still, the wind is onshore or cross-onshore from the ENE to NE, and the wave comment stays either "poor" or "marginal." The period drops to 10 seconds. It's just not coming together. The water temp remains about average.

Honestly, there isn't a single standout in this whole forecast. Don’t bother checking the buoys; this is a two-week stretch to save the petrol and maybe work on your pop-up. The break is a river mouth, so when it's ugly, it's really ugly. It’s a blank run, and that’s pretty normal for this area when the trades lock in like this.

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.
