The Lowdown

G'day, Rusty here, and I've gotta be straight with you – the next couple of weeks are looking pretty flat for the most part. We're in for a long stretch of small, weak energy before things finally start to show a bit of life late in the run. The first real surfable day doesn't pop up until the second week of August, so if you're itching to get wet, you'll need some patience.

Alright, let's get into it. For the first week and a bit, from Friday the 31st of July right through to the 9th of August, the energy is just not there. We're talking combined swell energy values of 0 to 64 (weak), and the odd tiny wave that shows up is mostly from the north and northwest, with periods all over the shop. The highlight of this quiet period is probably the glassy conditions on Sunday the 2nd of August afternoon with a tiny 0.3ft north swell, but with a period of 9 seconds and weak energy (15), it's a real wave-riding challenge.

Now, the first real glimmer of hope arrives on Sunday the 9th of August afternoon. We've got a 2ft west swell rolling in with a 14-second period, and the combined energy jumps to 153 (moderate). The wind goes glassy, so it's clean, but the quality is still described as "surfable waves but very ordinary conditions" – it's a start, but don't expect magic.

The pattern continues to build, slowly. Monday the 10th of August afternoon sees a 2ft west swell, still 14-second period, and energy up to 198 (moderate). Again, glassy conditions make it look okay, but the wave quality is "very ordinary." Tuesday the 11th of August afternoon is a repeat offender with a 2ft west swell, same period, energy at 138.

But the standout of the entire forecast – and I mean the one bright spot that's worth circling on the calendar – is Saturday the 15th of August morning. The swell builds to 3ft from the west, with a 15-second period, and the combined energy hits 347 (moderate). The wind is light onshore, which is a shame, but that's the biggest, most energetic swell we've seen in the entire run. It's a long-period groundswell, so it'll have nice shape and energy, but it's a slight air, so the wind is very light. For Sixtynine, which is exposed to a WNW optimum, this west swell is a solid match. The break is fairly consistent, so you've got a good chance of finding a few. It's still a small wave, so it's not going to be a world-beater, but after two weeks of dust, it's the best we've got.

So, if you're keen, keep your eyes on the 15th of August. The rest is a waiting game. Stay patient, mates.

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.
