The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the table for the next couple of weeks.

Straight up, it’s a grim start. We’re looking at a long dry spell with barely a ripple for the first week and a half. From Thursday the 30th of July all the way through to Saturday the 8th of August, the surf is flat or near flat, with tiny swells and poor conditions. The wind is all over the place – cross, cross-on, and cross-off – and the energy in the water is pathetic, with combined swell energy readings mostly in the teens or single digits. You’d be better off doing something else. There’s nothing to ride, and the models are showing zero hope.

We finally get a little pulse of life starting on Sunday the 9th of August. It’s not pumping, but at least it’s surfable. The main break to keep an eye on is Sixtynine. It’s fairly exposed to the swell, handles a WNW direction well, and the consistency is decent. On the 9th, the morning is showing a 2ft swell from the west, with a period of 12 seconds, and a cross-off breeze – that’s clean. The combined energy is moderate (148). By the afternoon, it goes glassy, which is a major positive. The water temp is sitting at 80°, which is about average for this time of year, so no surprises there.

The real standout, the one you want to circle on the calendar, is Friday the 14th of August. Through the morning we’ve got light rain and glassy conditions with a 3ft west swell, a 14-second period, and combined energy up to 264 – that’s proper moderate energy. The wind is calm, dead glass. The afternoon is even better: 3ft west swell, 14-second period, glassy, with combined energy hitting 329. This is the best on offer across the whole 16 days. The swell direction is right on the optimum for Sixtynine, and with the wind totally off, it’ll be clean and lined up. It’s a little small for experts but perfect for intermediates. Crowds are possible here, so don’t expect to have it to yourself.

Before that, there are a few other days that are worth a paddle if you’re desperate. Monday the 10th of August has glassy conditions and 2ft west swell with a 14-second period and combined energy of 234. It’s surfable but nothing special. Wednesday the 12th has a glassy afternoon with 2ft west swell and a 15-second period – very long period, which means longer lulls but better shaped waves. The energy is moderate (161). Again, not a standout, but rideable.

The rest of the second week is a mixed bag of small west swells, with the wind occasionally glassy or cross-off, but nothing that rivals that Friday the 14th. That day is the clear winner. The long range is promising but less certain, so keep an eye on it.

For now, the first week is a write-off. The second week starts to show signs of life, and that Friday is your best bet. Get out there if you can.

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.
