The Lowdown

Alright folks, Rusty here. Let’s break down what’s cooking for the next couple of weeks.

You’re looking at a slow start, no two ways about it. From the 1st of August right through to the 8th, it’s pretty flat. The swell energy is barely a whisper, with readings as low as 4 and 5 (weak energy), and most of the swell is 0.2ft to 0.3ft. A few glassy moments, like Monday afternoon the 3rd with calm winds, just can’t make something out of nothing. The water is sitting at 81°, about average for the season, so at least a paddle won’t freeze you.

Things start to stir on the 9th of August. Sunday afternoon brings a little 0.5ft west swell with a 14-second period, and the combined energy jumps to 103 (moderate). The wind is a light cross-offshore, cleaning it up. It’s small, but it’s surfable. Monday the 10th afternoon gives another glassy window with the same 0.5ft west swell and energy at 100.

The real standout, though, is Thursday the 13th of August. The afternoon session is the pick of the run. You’ve got a 0.9ft swell from the west-northwest, with a 13-second period, and the combined energy hits 290 (moderate). The wind goes glassy with a slight air movement. That’s clean, lined-up, and the biggest we’ve seen. That’s the one to circle.

Sixtynine is a consistent spot, fairly exposed and takes a west-northwest swell well, so this direction is spot on. With a 13-second period, it’s a groundswell that’ll give better shape and longer lulls between sets. At 0.9ft, it’s still very manageable for intermediates.

The days after step back a bit. Friday the 14th and Saturday the 15th have glassy afternoons with 0.6ft and 0.7ft west swell, but the energy drops. Sunday the 16th afternoon is glassy again with 0.8ft, but the direction is a little more north in the mix. Rideable, but the 13th is the one.

So, mark the 13th in your calendar. Not a big one, but it’s the cleanest, most reliable wave we’ve got.

Keep an eye on the forecast, and I’ll see you out there.

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.
