The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Tankers.
Honestly, the next week and a half is a bit of a grind. We’ve got a long flat spell to start, with nothing really worth paddling out for. The swell is just too small and weak for most of it, and the winds, while mostly cross-offshore, are blowing too hard to keep things clean. Even the bigger energy days, like the 22nd with a combined energy of 926, are still only pushing 2ft – not enough to get excited about. The water temp is sitting at 80°, which is pretty average for this time of year, so no surprises there.
The first real chance of something decent doesn’t show up until Monday the 28th of July. That morning, we’ve got a 6ft swell out of the east with a 13-second period, and the wind is a light cross-offshore breeze at 6 mph. The combined energy is 1327, which is moderate, but the waves will be clean and have some push. This is expert territory though – anything over 5ft is getting too big for beginners, and at 6ft, it’s for the experienced crew. The afternoon holds similar, with a 6ft east swell and the same light wind. That is the standout of the whole outlook. If you’re good enough, get on it.
After that, we get a weird little glass-off on Wednesday the 29th of July. The wind drops to zero, totally glassy, but the swell drops right back to 3ft and 2ft with a combined energy of 251 and 219. It’ll be clean but small. A fun session for a longboard or a fish, but nothing to write home about.
Then it’s back to the doldrums. From Thursday the 30th of July right through to Tuesday the 4th of August, it’s all poor surf conditions. The swell stays tiny, under 3ft, and the wind picks up into the fresh breeze range, making things bumpy and messy. The combined energy never gets above 472, pretty weak. It’s a real blank run for the area.
So, to wrap it up: the only true standout is Monday the 28th of July. Get out there early if you’ve got the skills. The rest of the window is a write-off for surfing.
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.
