The Lowdown
Alright, I’m Rusty, and I’ve been staring at the charts for your spot, Cogumelo. Let’s be straight with you – this 16-day window is a real struggle. There’s a big, long blank stretch to start, and honestly, we’re waiting over a week and a half before anything even remotely surfable rolls in.
The first week is a total write-off. From Saturday, the 1st of August, right through to the 10th, it’s “poor surf conditions” every single session. The swell is tiny, maxing out around 4 ft, but the wind is constantly cross or cross-onshore, just chopping everything up. The wave energy is weak, sitting between 31 and 140 (combined energy), which just isn’t enough to do anything with. You’d be better off doing something else.
Finally, there’s a little flicker of hope on Tuesday morning, the 11th of August. We get some glassy conditions with a light offshore breeze from the WNW. The swell is a modest 4 ft from the NW, with a short period of 6 seconds. The energy is still weak at 83 (combined energy), but it’s surfable – just barely. It’s an “ordinary conditions” kind of day, but at least the wind is clean. The crowds are often a problem here, so on a day like this, expect a few others with the same idea.
Then, on Wednesday morning, the 12th of August, we get another brief window. Glassy conditions again with a light SW breeze, but the swell drops to 2 ft from the WNW. With a period of 9 seconds, the energy is a bit better at 118 (combined energy), but it’s still small. It’s another “surfable but very ordinary” session.
The water temperature is sitting at 67°F, which is a bit colder than normal for this time of year, so don’t expect a warm welcome if you’re in a thin suit.
The 16th of August, Sunday morning, offers a sliver of hope with a cross-offshore breeze from the NNE and clean conditions. The swell is 2 ft from the NW, period 7 seconds, and energy at 66 (combined energy). Again, it’s surfable but ordinary.
Honestly, if you’re desperate for a paddle, the glassy mornings on the 11th and 12th are your only real shots. For the rest of it, with the wind and the small, weak swell, it’s more of a kiteboarding kind of setup than a surf one. Don’t bank on anything big, but forecasts can change, and this stretch of poor surf probably won’t last forever.
Rusty.

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.
