The Lowdown

Alright, folks, Rusty here. Let’s have a proper look at what’s coming our way for the next couple of weeks.

To be straight with you, the outlook is a tough one. For the next 16 days, there’s just no period of quality surf to get excited about. We’re looking at a long stretch where the conditions and the swell just won't line up. The first half of the window is particularly grim, with a gap of no real recommendation right through until the 25th of August.

Let’s start with the only break on the menu, Supertubos. The water is sitting at a very pleasant 69°F, which is pretty normal for this time of year.

Things kick off on Tuesday the 11th of August with tiny 1ft swell from the WNW. The combo of a northerly cross-offshore breeze and that small swell makes for poor surf. Wednesday the 12th and Thursday the 13th see a slight bump to 3ft, with the combined swell energy climbing to moderate levels (202), but the north/north-northwest winds keep it messy and cross-off. This pattern of small, wind-affected waves persists right through.

We hit a real lull from Saturday the 15th through the end of the third week, with waves dropping to a pathetic 0.3ft. That’s flat. You’d be better off doing anything else. There’s a long-period groundswell trying to show itself (16 to 19 seconds), but with next to no height, it’s just not surfable. The wind is also a factor; on Sunday the 16th, we get a light offshore breeze from the NE in the morning, but again, no swell to work with.

Even towards the latter part of the window, things don’t really fire up. Around the 21st of August there’s a touch of energy (2ft from the WNW) but the wind is a strong 22 mph from the north, making it a messy cross-off. The 25th of August finally sees a bit more size, with 2ft sets from the NW, but the period is short (8-9 seconds) which means weak, crumbly waves.

Overall, with such small, wind-affected swell and the spot being a beach and reef setup, the conditions look more interesting for a kite session than a proper paddle surf. It’s a blank run, and for this area, sometimes that’s just the way it goes. Keep an eye on the charts, but for now, it’s a rest period.

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.
