The Lowdown

Alright folks, Rusty here. Let’s see what’s on the menu for the next couple of weeks at Cogumelo. Clear skies are the norm across the period, but the surf is going to take its sweet time to get its act together.

Right now, it’s a tough start. We’ve got a dry spell of pretty ordinary conditions. The first few days, from the 10th through to the 12th, are a write-off. You’re looking at small, weak little waves with the combined swell energy barely hitting triple digits (71 to 168), and the wind is mostly cross or cross-on, which is just making a mess of the surface. It’s not worth paddling out for.

Things start to nudge towards just barely surfable by the morning of Thursday the 13th. The swell picks up a bit, coming from the WNW at about 3ft, but the period is a solid 10 seconds, which gives it some shape. The offshore wind on the morning of the 13th and 14th is light from the north, keeping things clean. The combined energy is now in the moderate zone (205 to 202), but the forecast still calls it marginal. You might get a few if you’re desperate, but it’s nothing to write home about.

The real standout, the only one that gets my blood pumping a little, is the morning of Monday the 17th. The wind drops to glassy, dead calm. The swell is a clean 3ft from the NW, with a 9-second period. It’s not a monster, but that glassy surface will turn it into a little gem. The combined energy is a moderate 177. The afternoon is a write-off again, so get it while it’s good.

The morning of Tuesday the 18th is also worth a mention, with flat calm winds again and a similar 3ft NW swell. It’s surfable, but the 17th morning is your best bet.

Now, we get another long gap. The rest of the week is a mix of onshore junk and tiny waves. Then, we look ahead to the second week. The morning of Friday the 21st sees a pulse of 5ft NW swell, but the wind is light and cross-on, which is better. The combined energy jumps to 335, but it’s still only marginal. Not a classic.

The following week, things get a bit more interesting, but also more uncertain. The morning of Monday the 24th has a 5ft NW swell with a light north cross-shore wind, and the energy is up to 366. But the big one to watch is the morning of Tuesday the 25th. A very long-period groundswell rolls in from the WNW at 15 seconds, with a swell height of only 2ft. That’s the kind of period that carries serious energy, and the combined energy is a whopping 453, which is strong. That’s a promising sign, but it’s a long-range call, so don’t bank on it being perfect. That long period will be lining up nicely for Cogumelo’s exposed setup, but it could be a bit shifty.

Overall, it’s a patchy outlook. The morning of the 17th is the true standout right now for a clean, fun session. The long-range pulse on the 25th is the one to keep an eye on for the future.

Rusty, signing off.

Information about the Cogumelo Surf forecast

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

Cogumelo is 29 km (18 miles) from Sines. If you plan a holiday in Portugal - Alentejo, look for hotels and other accommodation in Sines. Sines has rooms for a wide range of budgets as well as car hire and transport links.
