The Lowdown

Alright, let me take a look at what we’ve got here for Sixtynine.

Honestly, I’ve gotta be straight with you – this 16-day window is looking like a flat spell for the most part. We’re talking a lot of zeros on the wave energy, and what little swell pops up is tiny, weak, and barely registering. It's one of those stretches where the ocean just goes to sleep. From now through the end of July, there's basically nothing rideable. Then we roll into August and it stays just as quiet. There’s a gap of several days with no real surf on offer.

The first tiny flicker of life comes on Thursday the 30th of July in the afternoon. We’re talking a 1ft swell out of the southwest with a long period of 18 seconds. That’s a groundswell, but the combined energy is only 49 – real weak. Wind is light and variable, so it might look pretty but there’s just not enough juice to push a decent wave. This kind of long-period groundswell can be tricky on a beach break, running too straight, but if there’s a sandbar, maybe you could snag a waist-high one. Don’t get your hopes up.

Things stay marginal through the first week of August. Friday the 7th of August morning shows a 1ft swell from the SW, 14-second period, and the combined energy bumps up to 61 – still weak, but it's the highest number in the whole run. Winds look light with some cross-onshore texture. Still, 1ft is really small. Around the same time, we see a couple of glassy windows on the 7th afternoon and the 9th of August. On the 9th afternoon, there’s a 0.7ft swell from the WNW with a very long 16-second period, but energy is just 24. It’ll be flat, clean, and glassy – good for a paddle, not for riding.

If I had to pick the only true standout, and I mean the only one, it would be the morning of Monday the 10th of August. A 1ft swell from the WNW with a 15-second period and clean, light offshore wind. The energy is 42 – still in the weak range. It’s not going to be proper surf, but compared to the rest of this dead run, that morning might be the most pleasant for a longboard or a foamie in the ankle-to-knee high slop. Beginners might find something to do, but it’s hardly worth the trip. This is just one of those periods where you’re better off checking the local river mouth if it ever breaks.

Information about the Sixtynine Surf forecast

The above surf forecast table for Sixtynine provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Sixtynine can be found by selecting the local surf guide option on the grey menu. Our Sixtynine 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 (Sixtynine) 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 Sixtynine 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.

Sixtynine is 84 km (52 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.
