The Lowdown
Right then, let’s have a look at what’s on offer for Tankers. It’s a reef break, pretty consistent, but we’ve got a bit of a wait on our hands.
The first real surf worth talking about isn’t until Sunday the 19th of July. Before that, it’s a write-off – cross-shore winds, messy conditions, and tiny, weak swell. Honestly, you’d be better off doing something else. From Thursday the 16th right through to Saturday the 19th morning, there’s nothing doing. A solid four-day gap with no recommendations.
So, Sunday the 19th morning – that’s the first flicker of life. We’ve got a 4ft swell from the east, but it’s short-period stuff at 8 seconds, so it’s not going to have much grunt. The wind is cross-offshore from the east-northeast at 12 mph, which keeps things clean. The combined energy is moderate at 406. It’s marginal, but it’s the first thing that’s not a total dud.
Things start to look a bit more interesting from Monday the 27th of July. The morning brings a 4ft swell from the east with a longer period of 16 seconds, giving it some proper groundswell punch. The wind is a gentle cross-offshore from the northeast at 9 mph, so it’ll be clean. The combined energy is strong, clocking in at 1322. This is a standout window. The water temperature is about normal for the time of year, sitting around 80°, so no surprises there.
Then Tuesday the 28th of July morning is the best of the lot. We’ve got a 6ft east swell with a 14-second period – that’s a solid, powerful wave. The wind is virtually nothing, just a slight air from the east-southeast at 3 mph, making it glassy. This is prime for the reef at Tankers. The energy is strong at 1374. This is the one to aim for. Just be aware, the crowds are “often” here, so expect some company.
After that, it drops off again. Wednesday the 29th and Thursday the 30th see the swell fade and the winds turn more cross-shore, leaving us with small, weak waves. The last few days of July into the 31st are basically flat.
So, to wrap it up: the standouts are Monday the 27th and Tuesday the 28th of July. The Tuesday morning session is the absolute winner – clean, glassy, and a decent-sized groundswell from the east. Get on it.

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.
