The Lowdown
Alright, Rusty here. Let’s talk surf.
It’s a bit of a slow start right now, but there’s some serious potential building for the end of the week and beyond at Supertubes. We’ve got a long run of onshore and cross-onshore winds messing things up for the first few days, so you’ll want to pick your sessions carefully. The water is sitting at 67°, which is a touch warmer than average for this time of year – nice bit of warmth in the water.
Right now, Thursday the 16th is a write-off. It's 10ft from the WSW but with a cross wind and that moderate cross-shore chop, combined swell energy is strong (3611), but the quality just isn’t there. Friday and Saturday are even worse – strong winds, rain, and big messy swell. Saturday morning has a massive 18ft onshore swell with energy through the roof (9911) – that’s strictly for the brave or the crazy, and the wind is straight on it. Not good.
We start seeing a glimmer of hope on Sunday the 19th afternoon. The swell drops to a cleaner 10ft from the WSW, and the wind eases off to a gentle breeze. It’s still cross-onshore and a bit choppy, but the energy is moderate (3018) and you might find a few. Monday and Tuesday are still variable with wind, so nothing to get excited about.
Then comes Wednesday the 22nd. The wind finally shifts to a cross-offshore from the SSE, and the swell is a solid 13ft from the SW. The energy is strong (4814) and the water is clean. This is where it starts to get interesting. The period is 14 seconds, so it’s a proper groundswell with some punch. Not for beginners at this size, but for experienced surfers, it’s game on.
The standout window? Thursday the 23rd morning. Supertubes is the call. We’ve got offshore wind from the ESE at 12 mph, the swell is 10ft from the SW, period 14 seconds, and the energy is strong but manageable (2909). It’ll be clean, lined up, and firing. Crowds are possible here, so get there early. After that, Friday the 24th afternoon is a gem too – 6ft from the SW, a light offshore breeze, and a mellow clean surface. That’s a beautiful, fun wave for everyone.
The following weekend (26th and 27th July) keeps delivering with clean conditions and solid 7-8ft SW swell on the cross-offshore winds. Quality remains high, but by Monday the 28th the wind swings back onshore and it gets lumpy again. Then the last few days of July see a big pulse of WSW swell, but the wind is nasty – cross-onshore and strong – so it’s mostly a washout.
Overall, the best surf is from Thursday 23rd through Sunday 27th July. The absolute best sessions are Thursday 23rd morning and Saturday 25th afternoon. Don’t sleep on Friday 24th afternoon either – small but perfect.

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