The Lowdown
Alright, let’s get into it. The long-range charts are showing some serious potential, but we gotta wade through a bit of junk first.
The first few days are pretty gutless. Wednesday the 9th has a tiny 2ft to 3ft southwest swell with clean but weak conditions. Nothing to get excited about, honestly. We’ll see a quick push on Thursday though. The swell bumps up to 3ft to 6ft, and the morning looks proper—offshore wind at 12 mph and a clean 17-second pulse. That’s a sign of things to come. The energy is moderate (905 combined energy), and Super Tubes (Big Island) is the break to be at. It’s a reef and point set-up, so it loves this southwest direction.
Friday the 11th gets messier. Swell is 7ft and 6ft, but the wind swings onshore from the ESE, making it choppy. The afternoon turns poor. Saturday is worse—cross-onshore and onshore winds with 5ft to 6ft of bumpy swell. Let’s skip those days.
Now, Sunday the 13th is the first real standout. The morning glass is clean, with a light offshore wind and a 8ft southwest swell at 15 seconds. That’s proper groundswell. The energy is strong (2215), and the report says excellent conditions for experienced surfers. This is a “get wet” moment. Super Tubes will be firing.
After a smaller, cleaner window early next week—Monday and Tuesday mornings have glassy 4ft and 3ft swells—the ocean starts to really wake up. Wednesday the 16th is raw. The morning is cross-offshore with a 7ft southwest swell and a 16-second period, but that wind is blowing 28 mph. Energy is very strong (4597). It’s going to be grinding and powerful, but not easy.
The real monster shows up on Monday the 21st. The morning brings a 16ft southerly swell at 16 seconds. Combined energy is a massive 11471. That’s a big, serious day. Winds are moderate offshore, so it will be clean, but it is only for experts. This is the standout of the entire run. The afternoon backs off slightly to 15ft, still big and clean.
After that, Tuesday the 22nd gets stormy and poor with onshores. But the tail end of the run, Wednesday the 23rd and Thursday the 24th, cleans up again with 5ft and 4ft southwest swells under light offshore winds. A nice way to finish.
The water temp is about average for this time of year, so no wetsuit surprises.

Information about the Super Tubes Surf forecast
The above surf forecast table for Super Tubes provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Super Tubes can be found by selecting the local surf guide option on the grey menu. Our Super Tubes 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 (Super Tubes) 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 Super Tubes 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.
