The Lowdown
Alright, Rusty here. Let’s have a look at what’s shaping up for Sixtynine.
Well, mate, I’ll be straight with you – this outlook is a bloody tough one. We’ve got a massive dry spell on our hands. The forecast starts with a whole lot of nothing. From Wednesday the 22nd all the way through to Wednesday the 29th, there is absolutely zero surf on offer. That’s a solid week-plus of flat, poor conditions. The wind is all over the shop, mostly cross-shore, and the energy is just non-existent.
The first real whisper of life doesn’t show up until Thursday the 30th of July. It’s tiny, with a 1ft swell from the WSW, but the period is a very long 18 seconds – that’s proper groundswell energy. The combined energy is weak at just 20 (75 in the arvo). The morning is a write-off, but Thursday afternoon we get glassy conditions turning that tiny swell into something clean. It’s surfable, but honestly, it’s very ordinary. You’d be desperate for a paddle.
Things pick up a bit on Friday the 31st with a 2ft swell from the W, period 13 seconds. The energy jumps to 161 in the morning. The wind is cross-onshore though, so it’s a bit messy. The afternoon gets a moderate cross-shore chop – not great.
Saturday the 1st of August brings a 2ft W swell. The morning looks clean with a fresh cross-offshore breeze from the NE, and the combined energy is 170. That’s the best-looking window in the whole run. Not big, but clean and rideable. The afternoon gets a bit choppy again.
Sunday the 2nd of August continues with that 2ft W swell. The morning is clean with a gentle cross-offshore breeze, and the energy hits 207 – moderate but still the strongest of the whole period. The afternoon stays clean with light winds. This is your best bet for a few fun, small waves.
After that, it fades again. Monday the 3rd and Tuesday the 4th see the swell drop back to 2ft and then 1ft, with energy falling off a cliff. By Wednesday the 5th and Thursday the 6th, it’s back to tiny 1ft slop, although there are some glassy periods in the afternoons.
So, the standout is the window from Saturday the 1st of August morning through to Sunday the 2nd of August afternoon. It’s the cleanest, most consistent pulse of the whole 16 days, with a 2ft W swell, good winds, and moderate energy. Don’t expect anything epic, but it’s the only real chance for a decent session.
The water temp is about average for the time of year, not worth getting excited about. Crowds at Sixtynine are possible sometimes, and with so little surf around, you can bet the few who are keen will be out there.

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.
