The Lowdown
Alright, let’s get into it. This is Rusty, and I’m looking at the next 16 days for Tankers.
Right off the bat, I gotta be straight with you: the first few days are a bit of a struggle. We’ve got a little bit of size, but the wind is a constant cross-offshore from the ENE, which isn’t the worst direction, but it’s just not lining up with the weak, short-period swell. The water temp is sitting at a nice 80°F which is pretty average for this time of year, so that’s a small win.
The first real chance to get a wave in is on Monday morning, the 20th of July. It’s small, only 2ft, but it’s a long-period 16-second groundswell from the S. The wind is light at 6 mph, which is a major positive. It’s going to be clean, but it’s a beginner wave at best. The energy is moderate (397).
We then hit a bit of a flat spell. Tuesday through to Saturday morning (21st-25th) is mostly marginal or poor. The wind is up, the swell is mixed, and nothing is really coming together. The energy starts to build, but it’s not the kind of energy we want.
Then, on Sunday the 26th of July, we start to see something. The morning shows a 4ft swell from the E with a 16-second period. The energy is strong (1353). The wind is still a cross-offshore at 12 mph, which keeps it clean. This is the best looking window for the first week. It’s a solid, consistent groundswell, but that 16-second period can make it a bit straight at a beach break. It’s not a stand-out, but it’s the pick of the early bunch.
Now, the real talk. Look at Friday the 31st of July. The afternoon session is *the* one. We’ve got a 4ft S swell with a reasonable 11-second period, but the wind is glassy. Absolutely glassy. That’s a major positive. The energy is very strong (1238). This is the best on offer. It’s clean, it’s got some push, and it’s marked as excellent for experienced surfers, but it’s definitely not a beginner wave. This is the one to circle on the calendar.
After that, the first week of August rolls in with more cross-offshore trade winds and a mix of short-period E swell and longer period SSW swell. The energy is moderate to strong, but the wind is up, and the quality is just marginal. The afternoon of the 2nd of August has a 6ft E swell, but it’s a short 8-second period, so it’s going to be a bit of a mushy mess.
So, to wrap it up: the first week is a grind with a few clean but small windows. The standout is the glassy afternoon on the 31st of July. That’s the one session you don’t want to miss. After that, it’s a lot of average to poor conditions with a bit of size but not much quality.
Rusty, signing off.

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.
