The Lowdown
Alright, surfers. Rusty here. Let’s talk about what’s cooking in our local waters.
It’s a pretty quiet start, and honestly, for the next few days, you’re better off doing something else. We’re looking at a real dry spell to kick things off. The first seven days or so are a write-off for any decent surf, with tiny, weak swells and messy winds. The energy just isn't there. There’s a bit of a pulse building around the 23rd and 24th of August, but the wind is straight onshore and the surf is ragged, so it’s not worth paddling out for.
The first real glimmer of hope shows up on the 26th of August. We start to see some improvements, but it’s still marginal. The real standout, the one you want to circle on your calendar, is the afternoon of the 27th of August at Supertubos (Portugal). We’re looking at a solid 6ft swell from the NW, with a period of 10 seconds. That’s proper groundswell. The combined energy hits 735 (moderate to strong), so there’s some punch. With a light, cross-offshore wind from the W, it should be clean and holding shape. This is easily the best window in the entire 16-day forecast.
The 28th of August has some potential too, with a similar 6ft NW swell, but the wind is a bit stronger. It’s still a cross-off, so it’ll be ridable, but the 27th afternoon is the pick.
After that, things drop off again. The 29th through to the 4th of September is more small, weak surf and clean but empty conditions. A couple of afternoons on the 1st and 2nd of September show a 5ft NW swell pushing through, but with that fresh cross-off wind, it’ll be lumpy and hard work. Keep your expectations low for that second week.
So, to sum it up: the first week is a ghost town, the second week has a couple of potential days, but the absolute best on offer is the afternoon of the 27th of August. That’s the one to go for.
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.
