The Lowdown
Howdy, Rusty here. Let’s cut to it: the surf over the next couple of weeks is mostly a waiting game. There’s a lot of flat, weak junk to get through before we see any real swell.
Right off the bat, and for about a week, it’s ankle-biters. Waves are under 2ft, with short-period slop and a lot of cross-off breeze. The energy is weak, mostly in the single digits to the 60s. It’s not until Wednesday the 16th that we see any bump—a clean but small 3ft NW swell—but the wind is up and it’s still not enough to get out of bed for.
The following week is where the magic happens. Friday morning, the 19th, a proper groundswell arrives. We’re looking at 4-5ft of northwest swell with a 13-second period. The energy reading is 637, which is some serious power. And the wind is dead calm. This is the standout morning—Supertubos (Peniche) is going to be firing. Glassy, lined-up, and with that long-period energy, it’ll be a proper session. Mark this one down.
That afternoon it gets a little crossed up, and it eases off slightly, but then Saturday morning the 22nd gives us another gift. Again, 4-5ft of northwest groundswell, 12-second period, and glassy conditions. Another absolute ripper of a morning. Energy is 572. This is your second big one.
After that, we drop back down, but there’s a fun, clean 3ft pulse on Wednesday afternoon the 24th with light offshore winds. Not as big, but still worth a paddle.
Water temp is about normal for the year. With the bigger swells hitting 4-5ft, that’s getting a bit chunky for beginners, and with those long periods, the beach breaks might get a little shifty. Supertubos will handle it best.
So, there you have it. A week of nothing, then two killer mornings. Don’t sleep on the 19th and the 22nd.
Later, 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.
