The Lowdown
Right, listen up. Rusty here with a look at what’s on offer for the next couple of weeks. It’s a bit of a mixed bag, but there’s light at the end of the tunnel, especially for those who can pick their moments.
We’re starting off flat and quiet. Nothing is happening for the first few days. The water temp here is sitting at 68°F, which is pretty normal for this time of year, nothing unusual.
Thursday the 3rd and Friday the 4th are a write-off. Tiny, weak little waves with not enough energy to get excited about. The combined energy is barely registering, 28 and 75, so it’s weak. Even with light winds the waves are just poor. Saturday and Sunday will see a tiny bump, with a combined energy getting into the low hundreds (101 to 156), but the swell is still small and ordinary. It's not worth paddling out for.
Monday the 7th is when things start to get interesting, but it comes with a strong wind. We see a jump in swell to 5ft from the WNW with a period of 12 seconds – that’s proper groundswell energy getting in there with a combined energy of 554. The problem is the N wind is blowing at 16 mph, keeping it from being clean. This is a setup that might be more fun for the kite crew than the paddle crew at a beach and reef break like Supertubos.
There’s then a gap through the middle of the week with almost no swell, just tiny dribbles. The wind stays howling from the north, 12–19 mph, so it’s not just flat, it’s blown-out flat. Not worth a look.
Then, we hit the standout window. Monday the 14th morning is the one you want to circle. We get a solid 4ft swell from the NW, with a long 11-second period, generating a combined energy of 413. That’s a solid, moderate energy swell. And the wind, mate, a light NNE offshore breeze at just 6 mph. That means clean, lined-up waves at Supertubos. It’s a fairly consistent spot and swells from the SW are what it really loves, but a NW with good period and offshore wind? That’s going to be special. It gets a bit chunky in the afternoon as the wind swings cross-shore.
Before that, Sunday the 13th morning is worth a mention for the glassy conditions, but the swell is small, just 3ft. It’s a nice, clean board session for a beginner, but not a standout.
After the 14th, things get a bit messy again with cross-shore winds on the 15th and 16th. The swell sticks around at 4 – 5ft, but the 12 mph wind makes it ordinary. The real winner is that Monday morning session. Get it while you can.
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.
Supertubos is 2 km (1 miles) from Peniche. If you plan a holiday in Peniche, look for hotels and other accommodation in Peniche. Peniche has rooms for a wide range of budgets as well as car hire and transport links.
