Alright, Rusty here. Let’s break down the Sixtynine forecast.
First thing, the water’s running about 81°, which is a touch warmer than normal for this time of year. That’s a nice bonus.
We’re staring at a long, flat stretch from Friday the 3rd all through the first week. Nothing worth a paddle until around Monday the 13th, and even then it’s poor. On Tuesday the 14th, a 3ft west swell rolls in with 17-second period – that’s long-period groundswell with moderate energy (364) but the wind is light cross-onshore, so not clean. Wednesday the 15th bumps to 3ft from WNW, 16-second period, energy jumps to 421. Still, the wind isn’t cooperating fully.
The standout hits Thursday the 16th. By Thursday afternoon, the wind goes completely glassy – dead calm. We’ve still got a 3ft west swell running at 15 seconds. That’s a long-period groundswell, good for points and reefs, and the energy is still solid at 275. Sixtynine is consistently breaking for intermediate surfers, fairly exposed to the swell, and that WNW optimum direction matches up nicely with the forecast. This is the one session to aim for. The glassy conditions will make for clean lines, even if the long period might see the swell running a bit too straight for a peaky beach break.
After that, it fades. Friday the 17th drops to 2ft with cross-shore wind and chop, and Saturday the 18th gets small again with energy under 100.
Bottom line: sit tight through the first week and a half. Your best bet is Thursday the 16th afternoon. Calm winds, waist-chest high, long-period west swell, and clean. That’s the pick of the entire run.
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.
