The Lowdown
Alright, Rusty here. Let’s talk about Tankers. The water’s sitting at 81°, and with a temperature anomaly of just 0.5°, it’s about as normal as it gets for the time of year – no surprises there.
We’ve got a bit of a waiting game ahead. The forecast opens with a run of days where the surf is just not cooperating. Sunday the 30th and Monday the 31st of August, plus Tuesday the 1st of September, all have small swell and a steady cross-off breeze that keeps it clean, but the waves are weak and unrideable. The combined swell energy is low, sitting between 349 and 498 (moderate). It’s frustrating, because the conditions look clean, but there’s just no push.
The first glimmer of something arrives on Wednesday the 2nd of September. It’s still marginal, with a 3ft swell from the south at 16 seconds, and a combined energy of 602 (moderate). The morning offers a chance, but the wind is a cross-off from the ENE at 15 mph, so it's clean but not quite firing. Thursday the 3rd drops back into poor territory.
Then we get a bit of a shift. Friday the 4th of September sees a bump in size – 7ft from the east in the morning, building to 8ft in the afternoon, but the period is a short 8 seconds and the wind is howling from the NE at 25–28 mph. The combined energy jumps to 962 (strong) and then 1378 (very strong). This is a messy, lumpy setup. For experienced surfers only, and honestly, with that wind and short period, it might be more interesting for the kite crew than paddle surfers.
Saturday the 5th of September is the standout if you’re keen. The swell is 6ft from the SSE with a 10-second period, delivering a combined energy of 1504 (very strong). The wind is cross-shore from the east at 19 mph, and there’s a fresh cross-chop making it lumpy. It’s not classic Tankers, but there’s size and power. It’s a marginal call, but it’s the best we’ve got for a while.
After that, Sunday the 6th and Monday the 7th drop back into a poor pattern with small swell and strong cross-off winds. Tuesday the 8th of September brings a morning of offshore wind from the north at 25 mph, with a 8ft east swell at 9 seconds and a combined energy of 1784 (very strong). That’s a big, powerful, offshore-clean setup, but it’s going to be a battle to get out and the waves will be heavy. Expert-only territory.
The rest of the second week is a mix of small, clean surf with long-period groundswell from the SSW, but the energy is moderate and the conditions are either marginal or poor. There’s nothing that jumps out as a solid go-to.
Overall, the best bet in this 16-day window is Saturday the 5th of September for the size and power, or Tuesday the 8th of September if you’re an expert and can handle a strong offshore wind and heavy 8ft east swell. Everything else is a waiting game.
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.
