The Lowdown
Alright, Rusty again, talking about Tankers. We’ve got a slow start this week, but the second half holds some promise if you’re patient.
Kicking off Friday 17th through Sunday 27th, it’s mostly small surf – 2 to 4 feet, with a few pulses of longer period SSW swell around 16 to 20 seconds. The wind is mostly cross-off or cross, with moderate to fresh breezes, so the surface isn’t glassy but there are cleaner spells, especially Monday 20th and Tuesday 21st. Those days bring moderate energy readings of 397 to 498, but the swell height is only 2 to 3 feet, so it’s not big. Water temp is about 80°F, normal for this time of year.
Now, from Sunday 26th July, the surf builds. Sunday has 4 to 4 feet from the east with a 17-second period, and the combined energy jumps into the strong range – 1319 in the morning, 1355 in the afternoon. Monday 27th sees 5 to 6 feet from the east, with a 16-second period and energy readings of 1461 to 2094. That’s proper groundswell, and the wind stays cross-off with moderate to fresh breezes, so the waves should be clean and well-shaped. Tuesday 28th holds 7 to 7 feet from the east, 14 to 15-second period, and energy readings of 1893 and 1787. That’s strong to very strong wave energy. The wind is light and cross-off in the morning, gentle in the afternoon, so conditions should be clean. That 7 to 7-foot range is big – only for experienced surfers. East swell at Tankers works on the reef, but with those long periods, expect powerful, spaced-out sets. Crowds are likely here – it’s often a busy spot.
After that, the swell drops off fast from Wednesday 29th July, with 2 to 3 feet and energy falling to 227. The rest of the period through 1st August is small and unremarkable, with light winds and some chop, but no standouts.
The clear standout is Monday 27th July through Tuesday 28th July – that’s the best stretch for size, period, and clean conditions. Get out there if you can.
Stay tuned.

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.
