The Lowdown
Alright, Rusty here. Let's have a look at what's on the menu for Tankers.
It's a pretty quiet start to the forecast period, mate. The first few days have some waves but they are mostly small and the wind is a constant cross-offshore breeze that's just not doing us any favours. The real action doesn't kick off until the middle of next week, and even then it comes with a whole lot of wind.
The best of the best is shaping up for Wednesday, August 12th and Thursday, August 13th. We've got a solid S swell pumping in, with chest to head high sets around 3.3ft to 4.3ft. The swell period is a long 16 to 18 seconds, which is proper groundswell energy. The combined energy is moderate to strong (1032 to 1086) on Wednesday morning, so there's some real push behind it. The wind is still a cross-off from the ENE, but it's clean. This is your window for a decent session. The reef at Tankers is exposed to the S swell, so it should handle that direction well.
Now, the weekend of August 15th and 16th gets a bit wild. The swell jumps up to a solid 11.5ft on Saturday and Sunday morning, but the period drops to 9-12 seconds and the wind is howling. That's a lot of power (combined energy 2584 to 4500) but with a strong breeze to near gale, it's going to be a washing machine. This is expert-only territory, and honestly, it's looking more like a kite session than a paddle session. We'll be giving that a miss.
After that, the swell drops off fast. By Monday the 17th, we're back to small 3.0ft waves, and the rest of the week is tiny, poor surf with a cross-off breeze. Nothing to get excited about.
So, for the standouts: Wednesday, August 12th is your best bet. The early session with 3.3ft of S swell at 18 seconds and moderate energy (1032) is the pick of the forecast. It's not perfect, but it's the cleanest, most consistent wave we're going to see. A close second is Thursday, August 13th morning, with a bit more size (4.3ft) and similar conditions. The water temp is about average for this time of year, so no surprises there.
Crowds at Tankers are often here, so expect some company on those good days.
That's it from me. Keep your eyes on the horizon.

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.
