The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
First off, it's a bit of a quiet start at Tankers. The waiting game is on, because there’s barely a ripple worth getting wet for until late August. You’re looking at a solid gap of about eight days where nothing really gets the heart pumping. The good news is that this spot is a consistent reef, so once it turns on, it usually stays on.
Come the 25th of August, things start to get interesting. Monday morning kicks off with a bump in energy, a clean 6 ft east swell pushing in, backed up by moderate energy readings around 724. The wind is a solid cross-offshore, so the faces should be looking tidy. That easterly swell keeps building through Tuesday and into Wednesday, with the combined energy climbing into four digits – well into the moderate range (1093 on Wednesday morning). By the 26th, we're seeing 7 ft of east swell, and that afternoon a 4 ft south groundswell rolls in with a nice long 12-second period. The wind holds cross-off and the water is clean; that’s a proper little window.
The standout has to be the 27th of August, Thursday morning. The swell is pushing 8 ft from the east, and the energy reading is a solid 1553 – that's a serious amount of juice in the water. This is expert territory for sure, with the size and power. That said, the period is only 8 seconds, which means it's a windswell, so it might wall up a bit. Still, with clean conditions and a good cross-off breeze, it’s the biggest and most powerful day on offer. The afternoon holds at 8 ft with clean conditions, just a touch smaller.
After that peak, the surf drops away quickly. By the 28th and into the weekend, we’re back to knee-high slop with poor conditions and low scores. Not worth paddling out for.
Overall, if you’re an experienced surfer, pencil in the 27th of August. That’s your best shot at some real power. For everyone else, the smaller but still clean days around the 25th and 26th are your safer bet.
Water temps are about average for the time of year, nothing strange going on 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.
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.
