The Lowdown
Alright, Rusty here. Let's chew the fat on what's coming up at Tankers.
It's a rough start, no two ways about it. The weekend and the start of next week are a write-off. The wind is howling from the east and northeast at 25-30 mph, just ruining any chance of a decent wave. There's some size on the 15th and 16th, with swell hitting 8-10ft, but the period is short and the wind is all over the place – cross-off to cross-onshore. It's a mess. Forget paddling, this is more of a kiteboarding scene.
Mid-week, the swell drops right off to 2-3ft and the energy fades away. The wind eases a touch, but the waves are just too weak to bother with.
Now, here's the light at the end of the tunnel. The whole forecast hinges on the 27th of August. That Thursday afternoon, the wind goes totally glassy – dead calm – and a 4ft groundswell rolls in from the east with a very long 17-second period. The energy is strong, up around 1392. That's the kind of long-period swell that loves a reef like Tankers. It'll be clean, lined up, and proper quality. Not massive, but the conditions will be as good as it gets. The morning of the 27th has some swell too, but the cross-onshore breeze will mess with it. The afternoon is the session to wait for.
After that, the 28th and 29th have some leftover swell, but the wind picks up and the period drops, so it's not the same story. The 27th afternoon is the only true standout in this entire 16-day window.
So, be patient. Mark the 27th of August on your calendar. That's the day Tankers could be absolutely firing with clean, glassy conditions and a proper groundswell. It's a long way out, so keep watching, but it's got real promise.
Rusty.

Information about the Tankers Surf forecast
The above surf forecast table for Tankers provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Tankers can be found by selecting the local surf guide option on the grey menu. Our Tankers 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 (Tankers) 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 Tankers 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.
