Alright, Rusty here. Let’s have a look at Sixtynine.
Honestly, for the next 16 days, Sixtynine is pretty quiet. The first week and a half is mostly flat or tiny, with the odd pulse of weak, short-period swell coming from the west, but it’s getting chopped up by cross-shore winds and there’s just no energy to get excited about. The water’s a touch warmer than normal for July, sitting around 81°, but that won’t save a flat spell.
We finally see a little life kicking in from Tuesday the 14th of July. That afternoon brings a small 2ft west swell with a period of 17 seconds – that’s long-period groundswell, so decent shape potential, and the wind turns glassy. Wave energy is moderate (217). It’s still tiny, but it’s the first time things get surfable. The Wednesday and Thursday after that see similar small 2ft west swells, with glassy or clean conditions on the 15th afternoon and the 16th afternoon. The energy holds in the moderate range (239 to 261). Nothing big, but for a patient surfer on a longboard, there’s a window to get a few clean ones. Crowds are only sometimes an issue here, so you might have it to yourself.
The best of the run looks like Thursday the 16th of July afternoon: 2ft west swell at 15 seconds, clean with a light NE cross-offshore breeze, and the energy peaking at 261 – the highest of the whole outlook. That’s the standout, but it’s still a small wave.
From Friday the 17th, things start to fade again. Swell drops back to 2ft, then 2ft, and by the second week we’re back to tiny 0.9ft-1ft west-northwest slop with light breezes. The last half of the 16-day run has long gaps of nothing worth paddling for. A quick spike on Wednesday the 22nd of July of 2ft west swell (122 energy) but with onshore wind, so not worth the drive.
Keep your expectations low on this one, mate. There’s no proper swell on the horizon. If you’re jonesing, chase those glassy afternoons mid-month for some longboard fun.
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.
