The Lowdown

Alright, let's break it down. The surf has been pretty lackluster, and we're in for a bit of a dry spell before things get interesting. It's a waiting game, so let's see what's on the menu.

We start at Hakalau. For the next several days, it’s small and junky. The waves are going to be in the 3-5 ft range, mostly from the E, with a short period around 8 seconds. It's just not going to have any push. Morning on the 8th has light winds but the waves are weak. The combined energy is around 203, which is weak, and the report says "poor surf conditions." The water temp is 80°, which is about normal for this time of year. That ENE wind is offshore for this spot, but the swell isn't doing anything.

The first real chance of something bigger comes in around the 14th, a Friday. The swell is predicted to jump to 15 ft with a 14-second period, and the energy is skyrocketing to 8385 – that is strong. But there's a catch. It’s showing rain showers and the comment says it’s "marginal surf forecast or questionable tide conditions." So it's not a sure bet.

Then we get to the afternoon of the 14th, and that's when things go crazy. The swell is predicted to be a massive 21 ft from the E with a 15-second period. The energy reading is 16784, which is very strong. The comment says the wind and tide are favorable, but the swell is just too big for this break. This is a river break so at that size it's going to close out and be super dangerous. It's really only for the brave, and we don't want to put anyone in harm's way.

After that massive pulse, the 15th is a mess. The wind is howling from the NE at 43 mph, which is gale force, and it's blowing that big swell into complete chaos. The energy is still strong, but the report is clear: "gale force cross-onshore and completely blown out." We don't want to be anywhere near the water then. That's more of a kite-surfing day if you're into that sort of thing.

The next few days settle down again but stay junky. The swell drops back to 5-7 ft with short periods and onshore winds. It's the same old story.

Finally, we get a few days of decent conditions around the 19th and 20th. On the morning of the 19th, we have light winds and a 4 ft swell. But it's still a short period, low energy, and it's considered "marginal." It's still not great.

The rest of the window just fades out with small, weak swell and cross-onshore winds. It's pretty much a wash.

So, what's the best on offer? Honestly, it's not much. The first standout is the massive swell on the 14th, but it's way too big. If you're a pro and can handle that kind of power, it might be a spectacle, but for everyone else, stay on the beach. The other, more realistic option is the morning of the 19th. That 4 ft swell in clean light winds could offer a couple of fun ones. It won't be big, but it might be clean. That’s the best we got for the near term.

Keep an eye on the forecast, though. The ocean rarely stays flat for this long. The long-range stuff is promising but less certain. We'll see.

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.
