The Lowdown
Alright folks, Rusty here. Let’s break down what’s happening at Tankers over the next couple of weeks.
Water temp is sitting at a seasonal 80°, nothing out of the ordinary. The wind is a steady cross-off from the east-northeast, which is a clean direction, but the swell just isn’t cooperating. For the first week, the wave heights are tiny, and the energy is mostly weak to moderate. The big issue is that the swell is coming from the east and south, not the south that Tankers really wants. The result is a whole lot of marginal to poor conditions. The first half of the outlook is a real grind.
From Sunday the 19th through to Wednesday the 23rd, there’s nothing to ride. The swell is barely 2ft to 3ft, and the period is confused. The combined energy is in the hundreds, but it’s not making waves. Thursday the 24th afternoon shows a small bump with 3ft of SSW swell and a moderate energy of 1159, but it’s still not scoring well. The wind is a fresh 35 km/h cross-off, which is clean but strong.
The one true standout, and the only window to get stoked about, is the morning of Sunday the 26th of July. We’re looking at 4ft of east swell, with a very long period of 16 seconds. That’s proper groundswell. The combined energy is a strong 1158, and the wind is a light 10 km/h cross-off, making it glassy. This is excellent surf for experienced surfers. The 4ft is a manageable size for a reef break. Just remember, long-period groundswell can break a bit straight on beach breaks, but at a reef setup like Tankers, it should be working. Crowds are often here, so you won’t be alone.
After that, Monday the 27th and Tuesday the 28th mornings hold onto 4ft to 5ft of east swell, but the wind picks up to 15-30 km/h, and the energy starts to fade. The later part of the period, from the 29th of July onward, drops back into small, poor conditions with cross-shore winds and chop. The 2nd of August afternoon shows a little hope with 4ft of SSW swell and a moderate 1219 energy, but it’s nothing special.
So, bottom line: the morning of Sunday the 26th of July is your best shot. The rest is a waiting game. Tankers is a consistent spot, so it won’t be flat forever, but this stretch is a test of patience.
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.
