The Lowdown

Right then, let’s have a look at what’s on the cards for the next couple of weeks. The big news is early on, but we’ve got a long dry spell to get through before things might get interesting again.

The standout session is undeniably Friday morning, the 28th of August, at Supertubos. It’s not often you get a setup like this. We’re looking at a solid 7ft groundswell from the WNW, with a long 11-second period – that’s proper energy. The combined energy is a strong 1123, so you’ll feel the power. The real kicker is the wind: dead calm, glassy. The water temp is sitting at 67°, which is just a touch cooler than average for this time of year, but nothing to worry about. This is the pick of the whole forecast. Get out there early.

That morning is the peak. By Friday afternoon, the wind swings NW at 9 mph and goes cross-shore, creating a bit of chop, and the quality drops right off. Saturday morning, the 29th, still has a clean 5ft swell from the NW, but the period has dropped to 9 seconds and the wind is a stiff cross-offshore 12 mph from the north. It’s surfable, but it’s a big step down.

From Saturday afternoon the 29th, right through to the afternoon of the 4th of September, we’re looking at a long stretch of poor conditions. The swell drops right out, periods get short, and the wind is mostly a strong cross-offshore northerly. It’s over a week of flat, rubbish surf. There’s a tiny blip on the afternoon of the 4th with a 2ft, 14-second swell from the NW, but the energy is weak (126) and the conditions are just ordinary.

Now, if you’ve got some patience, there’s a promising window for the morning of the 5th of September. The swell bumps back up to a clean 5ft from the NW, with a solid 13-second period and a combined energy of 786. The wind is light from the north at 6 mph, keeping it clean. It’s a week away, so keep an eye on the forecasts, but this could be a really good one. The afternoon will be a little more chopped.

The morning of the 6th of September is also worth a mention, with a 4ft groundswell from the NW (373 energy) and a light 9 mph cross-offshore breeze. It’s a decent session, but not the same quality as the 5th.

After that, the 7th and 8th of September are a write-off with strong winds and no swell. There’s a couple of tiny, long-period blips on the 11th and 12th, but the energy is too low to get excited about.

So, to sum it up: Friday morning the 28th is the absolute best of the bunch – get it while it’s clean. The morning of the 5th of September is the next real hope, but it’s a long way off. Be patient.

Rusty.

Information about the Supertubos Surf forecast

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