The Lowdown
Hey team, Rusty here.
Let’s talk about the next couple weeks. We got some energy moving, but the wind is gonna be the boss for a while. Water temp feels normal, about 81°F, nothing wild.
The real highlight is the last part of the window. Saturday, August 22nd afternoon, it’s gonna be deadly at Tankers. The ocean will be glassy with no wind, and you’ll find a clean 2-foot swell rolling in from the SSW with a long 15 second period. That’s proper groundswell, and it’ll be wrapping in nice. The energy is moderate at 266, but that flat surface is the main event.
Sunday, August 23rd afternoon keeps the good times rolling with a clean 3-foot swell from the SSW and a 14 second period. Light winds will keep it looking sharp.
Then we get a real push. From Tuesday, August 25th and into Wednesday, August 26th, the swell sizes bump up to 4 to 5 feet from the south, with very long periods of 16-18 seconds. The combined energy gets strong, hitting numbers like 1477 and 1714. That’s powerful, long-period south groundswell. For the experienced surfers, this is the best window, with the ENE winds keeping it decently clean. Anything over 8 feet is for experts only, and this stays in the capable intermediate to advanced range.
The weeks before that are a bit of a slog. From now through mid-August, we have consistent swell but the wind is mostly cross or cross-off, and often fresh. The swell stays small, 2 to 5 feet, but with the wind, the quality is just okay. For example, Saturday, August 15th has 5 to 6 feet from the east with a short 9-10 second period and strong breezes—that’s a choppy mess. It’s a wind swell session, and the energy is moderate. A lot of this early stuff looks more like a kiteboarding session than a surf session.
If you want the cleanest, most user-friendly waves, aim for that Saturday, August 22nd and Sunday, August 23rd window for the small but glassy conditions. The bigger, cleaner south swell from August 25th onwards is the real score for the crew that can handle it. Watch out for the crowds at Tankers though—they can get thick when the surf is good, so beat the rush.
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.
