The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for the Tankers reef. It's the only spot on the cards, so we're sticking with it.
Looking at the whole 16-day run, it’s a bit of a slow burn. The first few days are pretty much a write-off for a decent paddle. There's a sizeable gap here - from now, the 15th of August, all the way through to the 22nd, we're dealing with poor to marginal conditions. Big, raw energy early on, but the wind just messes it up. Then from the 22nd, we start to see some glimmers, leading to what looks like the real standout session right at the tail end on the 30th.
So, starting off, Saturday the 15th afternoon. We've got a solid 13ft swell from the east, period around 10 seconds, and the combined energy is pumping at a massive 3225. That's a lot of ocean moving. But it's blowing a near gale from the ENE. The surf is going to be a clean, blown-out mess; big, but ugly. Definitely not one for the beginner. This heavy swell (over 8ft) is strictly for experts only, and even then, the wind makes it a battle.
That big wind sticks around, making Sunday the 16th a scratch day too, with a cross-on breeze and lumpy conditions on a dropping swell. Monday the 17th sees the swell drop right off to 3ft, but we finally get some better cross-off winds from the ENE. However, at that size and with a very long 14-second period from the south, it's just marginal. A long-period swell like that can be tricky at a beach setup, but Tankers is a reef, so it might line up okay, but the energy is low. This pattern of small, clean but weak surf carries on through the middle of the week.
Now, here's where it gets interesting. Saturday the 22nd afternoon. The swell is still small at 3ft from the SSW with a 16-second period. The combined energy is a modest 387. But the wind… it's going glassy. A big, fat zero on the wind scale. That’s a major positive; the surface will be like a mirror. For such a small, clean right-hander on the reef, this is as good as it gets for the small stuff. It’s the first real highlight of the period, just a little gutless on size.
Everything else after that is pretty average. The best call of the whole outlook lands on Sunday the 30th of August. The morning looks promising, but check out the afternoon. We’ve got a 4ft swell rolling in from the east, with a 14-second period. The combined energy is a solid 935, and the wind is a light, cross-off breeze from the east. Those are some perfect building blocks. The conditions are flagged as "very good." For a consistent reef break like Tankers, that’s a standout session. The water temp is a balmy 82°F, and with the anomaly being only 1°F, it's pretty much what you'd expect for this time of year. Get on that if you can.

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.
Tankers is 5 km (3 miles) from Makakilo City. If you plan a vacation in Oahu, look for hotels and other accommodation in Makakilo City. Makakilo City has rooms for a wide range of budgets as well as car hire and transport links.
