The Lowdown

Alright, Rusty here. Let’s have a look at what’s cooking.

First up, Sixtynine. We’ve got a tiny bit of swell on Sunday the 19th, but it’s barely a ripple. The water’s sitting at 80.1°, which is pretty normal for this time of year. Sunday afternoon sees a 1-foot swell from the WNW with a 12-second period, and the combined energy is only 29 – that’s weak. The wind is offshore from the WNW at 3 mph, but the conditions are still poor. It’s just not doing anything.

Monday the 20th is more of the same: 1-foot, WNW, 12 seconds, 27 energy. The wind is onshore in the morning, and Monday afternoon goes glassy with a NNW breeze at 3 mph, but the swell drops to 0.7 feet. That’s not surfable.

Tuesday the 21st? Swell is gone by afternoon. Glassy conditions with no waves. Wednesday the 22nd through to Tuesday the 28th? Zero swell. Flat as a pancake. A long stretch of nothing. A few mornings with cross-shore breezes, but honestly, it’s just a blank run.

We get a little flicker on Thursday the 30th afternoon. A 1-foot swell from the SW with a very long 18-second period, combined energy of 49. Winds go glassy from the WNW at 3 mph. But the surf is still rated poor. That long period, tiny swell is just not going to wrap in with any punch.

Friday the 31st? Flat again. Glassy, but flat.

Saturday the 1st of August? Still flat. Sunday the 2nd morning bumps up to 1.3 feet from the SW at 9 seconds, energy at 31, but the wind is cross-onshore. Sunday afternoon goes glassy, 1.3 feet, SW, 9 seconds, energy 20. Still poor. Monday the 3rd afternoon goes glassy with a 1-foot WNW swell at 13 seconds, energy 32. Still poor.

There’s no standout in this window. No half-decent waves to get excited about. The whole 16-day run is a write-off for surf. If you’ve got a kite, you might get a bit of fun on the cross-shore days, but for a paddle surfer? Leave the boards at home. Forecasts can change, but right now, this is a long dry spell.

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.
