The Lowdown

G’day, Rusty here, love your work. Alright, let’s look at what’s coming up for Supertubes. This is a real reef set-up, so you know it’s got that shape and power when it’s on. The next 16 days have some serious ups and downs, so we need to pick the windows.

The first few days? We’re paying the price. Friday the 17th and Saturday the 18th are a write-off. Friday’s got a messy cross-shore wind and on Saturday, a big, powerful W swell from 15 ft to 16 ft rolls in, but it’s hammered by strong onshore winds. That’s not surfable conditions, that’s a washing machine. The combined energy is massive at 9128 on Saturday morning and 11476 on Saturday afternoon, but it’s all for nothing with the wind. Sunday the 19th is still pretty average with a cross-onshore wind and a lumpy 10 ft swell, so you’re dodging a bullet there.

Now, Monday the 20th is where we start to see a glimmer. The morning brings a clean 8 ft SW swell with a light cross-offshore NNE breeze. The combined energy is 2641, and it’s described as excellent for experienced surfers. That’s a window, but it’s not the main event.

The real standout? Look at Wednesday the 22nd. The afternoon has a solid 12 ft SW swell with a clean 14-second period, and the wind is a clean cross-offshore from the SE. The energy is 4124, and it’s clean. You’ll need some experience for that size, but the reef will handle it.

Then, hold onto your board for Thursday the 23rd. Morning and afternoon both have a moderate offshore wind from the east, with a 8 ft SW swell in the morning and 7 ft in the arvo. The period is a good 14 seconds, and the combined energy is 2223 and 1800. It’s described as excellent for experienced surfers. That’s a full day of quality.

Looking further out, the end of July and start of August have some epic potential, but it’s a longer-range call. On Wednesday the 29th, the afternoon shows a 7 ft SW swell with a 17-second period and a light cross-offshore breeze. The energy is 4156 and it’s excellent for experienced surfers. Then Thursday the 30th is a beauty: morning has a 6 ft SW swell with a 20-second period and light breeze, energy at 4610. The arvo is glassy with a 7 ft WSW swell and a 20-second period, energy at 4230. That’s a dreamy, long-period groundswell, which will be a treat on this reef. That’s the best on offer if it holds – a true standout day.

The crowd profile at Supertubes is “sometimes” busy, so you’ll likely have company on those good days, but it’s not a total circus.

The water temperature is about average for the time of year, so no need to dig out the steamer just yet.

So, in short: the first few days are a right-off. Monday the 20th is a small window. But the real action kicks off Wednesday the 22nd and Thursday the 23rd, with a potential classic on Thursday the 30th. Keep an eye on that one.

Rusty.

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.

Supertubes is 67 km (42 miles) from the city of Bunbury. If you plan a holiday in Margaret River, look for hotels and other accommodation in Bunbury. Bunbury has rooms for a wide range of budgets as well as car hire and transport links.
