The Lowdown
Alright, Rusty here. Let’s talk about what’s cooking at Tankers.
Honestly, looking at the whole 16-day window, it’s a tough run. Most of the time, the wind is blowing strong from the east-northeast, which is a cross-offshore breeze, but it’s howling. That keeps the ocean surface clean-looking, but it creates a lot of resistance and messes with the shape. The swell is small for the most part, and the wave energy is generally weak. There’s a real gap of poor conditions from Saturday the 22nd of August right through until at least the end of the month. What we’re seeing is a lot of “poor surf conditions” days. The water temperature is sitting at about 81° with a normal anomaly, so the water is fine for a long session, that’s not the issue.
The one real standout, and it’s promising but it’s a long way off, is the morning of Tuesday the 1st of September. That morning we’re looking at a 8ft swell from the east, with a period of 10 seconds. The combined energy jumps up to 1852 (strong energy). That’s a solid, powerful swell. However, the wind is still a stiff cross-off from the northeast at 22 mph, and the rating is marginal. For experts only. That size is way too big for beginners. The fact it’s a cross-off wind at a reef break like Tankers could make for some heavy, hollow waves if it lines up right, but it’s a tricky call. The rest of that week looks messy with onshore winds and rain.
So, the best bet on offer, if you’re an experienced surfer and can wait, is that morning of the 1st of September. Everything else before that is a write-off. The afternoon of Friday the 21st of August does have a glassy window with a 3ft SSW swell and a long 16-second period, which gives a combined energy of 404 (moderate energy). That’s a clean, small wave for the longboard or a fish, but don’t expect any power. For the rest of the run, expect a lot of strong, clean but blown-out conditions, and the swell just doesn’t build until that first day of September.
Stay patient, and wait for that big one in September.

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.
