The Lowdown
Alright, let’s switch over. This is Rusty, looking at the same stretch, but in feet and knots.
First real swell shows Thursday morning the 30th of July at Tankers – a consistent reef, exposed south. Water temp is about 80°, dead average for the season.
Thursday morning: wave height around 3 ft from the south, 14-second period – that’s a proper groundswell. Wind is cross-off from the ENE at 11 knots, keeping the surface clean. Energy is moderate at 441, so you’ll feel some push. For a beginner-friendly break, this is a nice little window. Afternoon gets choppy, so hit it early.
Friday the 31st is a wash – 19–22 knot winds and lumpy. Saturday the 1st of August has 8 ft waves, but only 8 seconds between them, and the wind is howling at 22 knots. Over 8 ft at a reef with that short period and strong wind? That’s for experts only, and it’s not clean anyway. Skip it.
From Sunday the 2nd through to Tuesday the 4th, we’re in a flat spell. Tiny waves, weak energy (70–280 on the scale). Not worth the walk.
Now, the good stuff. On Tuesday the 4th afternoon, the wind drops to zero – dead glass. Swell is small, only 1 ft, but it’s a long 16-second south-southwest pulse. Energy is low at 158, but at a reef, that long period can still give you a few silky rides on a log.
The real standout is Monday the 10th of August afternoon, and Tuesday the 11th morning. Monday afternoon: 3 ft south-southwest swell, 16 seconds, glassy (wind under 5 knots). Energy hits 714 – solid. The forecast says “expect very good surf conditions,” and I agree. That long groundswell wrapping into the reef with no wind – that’s as clean as it gets. Tuesday morning backs it up: 3 ft from the south, 15 seconds, glassy again (662 energy). Those two sessions are your best bets.
After that, it fades to smaller, cross-shore junk through the 12th to the 14th. Not much to get excited about.
Bottom line: the first week is a grind, but that 48-hour window starting Monday the 10th afternoon through Tuesday the 11th morning at Tankers – that’s the gold. Long-period south swell, glassy conditions. Get out there.
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.
