The Lowdown

Alright, Rusty here, and I’ve got to be straight with you. Right now and for the coming weeks, things are looking pretty bleak at Sixtynine. We’ve got a solid 16-day window ahead, but honestly, the surf is flat for the first five days, right through to Thursday the 30th of July. So, it’s a slow start.

Now, on Thursday the 30th of July, in the afternoon, a tiny pulse of swell sneaks in from the southwest, pushing about 1ft with a very long 18-second period. The water temp is sitting at 80°, which is about normal for this time of year. The wind goes glassy, which is a beautiful thing for the surface, but the combined energy is a weak 49. It’s not going to do much – small, infrequent lines that are hard to get excited about.

Friday the 31st keeps that tiny southwest swell going at about 1ft, with periods between 15 and 16 seconds. Winds are a gentle cross-shore, which is okay, but the energy is still weak, hovering around 50-54. There’s a small window Saturday afternoon, August 1st, with a 1ft swell from the southwest, 14-second period, and clean cross-offshore winds. But again, it’s small. Then Sunday the 2nd of August, the afternoon goes glassy with a tiny 1ft northerly bump, period around 9 seconds, energy at 15. It's flat calm conditions, but with almost no push.

Things don’t improve much in the second week. There are a few glassy moments, like on Tuesday the 4th of August afternoon with a 0.7ft northerly, 11-second period, and on Friday the 7th with a 0.7ft westerly, 13-14 second period. The real standout in this whole dry spell is Sunday the 9th of August. In the morning, we see a 2ft swell from the west with a 14-second period, and the wave energy finally climbs into the moderate zone at 104. The wind is light and onshore, so it won’t be clean, but in a period of nothing, it’s the biggest bump we have. It’s too small and choppy to call a proper standout, though.

The bottom line: this is a blank run for Sixtynine. It’s small, inconsistent, and the few moments of glassy conditions come with barely any swell. The 16-day window offers nothing that will get a surfer out of bed. Don't worry too much though, forecasts can change.

Rusty.

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.
