G’day, Rusty here. Alright, let’s be straight with each other – this 16-day window for Sixtynine is a tough one. We’re staring down the barrel of a long, flat spell with barely a ripple worth paddling for. The first proper surf recommendation doesn’t pop up until the afternoon of Tuesday the 14th of July, so we’ve got a solid gap of about a week with nothing to offer. After that, the options are marginal at best, and the run fades out again by the 22nd. It’s one of those blank runs that feels more normal for the area when the swell just doesn’t fire.
The water temperature is sitting at 80°, which is a touch warmer than normal for this time of year, so you’ll be comfortable in a shorty or just boardshorts if you’re keen.
Now, the standout, if you can even call it that, is the afternoon of Tuesday the 14th of July. The swell is tiny at 2ft from the west, but the period is a long 16 seconds, so it’s a proper groundswell with some energy. The combined energy is moderate (198). The real kicker here is the wind – it’s glassy, dead calm, which is a massive positive for a break that’s fairly exposed. The waves will be clean as a whistle, but don’t expect much push. It’s a day for the log or a longboard, and you’ll be scratching for anything over waist-high. The break is rated for intermediate surfers, and it’s consistent, which is a help, but the crowds are listed as “sometimes”, so you might have a few mates out there.
The next best look is the morning of Wednesday the 15th of July. The swell bumps up to 3ft from the west, still with a long 16 second period, and the combined energy is strong (314). The wind is a light cross-onshore from the NNW at 6 mph, so it’s clean enough but not as perfect as the glassy day before. The surf is still marginal, so don’t get your hopes up for barrels.
The afternoon of the 15th and the 16th are similar – 3ft from the west, cross-shore winds, and marginal conditions. The energy stays strong, but the quality just isn’t there for a proper session.
The 17th of July drops back to 2ft, and then it’s all downhill from there. The 18th is 2ft, and by the 19th we’re back to 1ft. The 21st and 22nd are flat as a pancake.
Honestly, if you’re desperate for a paddle, hit that Tuesday the 14th afternoon for the glassy conditions. Otherwise, save your energy and wait for the next system.
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.
