The Lowdown
Alright folks, Rusty here. Let’s break down what’s comin’ for our stretch of coast over the next couple of weeks. I’ll be straight with you – it’s a real dry spell for the most part. We’re lookin’ at a long stretch of small, choppy, and generally poor conditions, but there’s a tiny glimmer of hope way out at the end of the forecast.
The whole run starts with a big gap of nothin’ worth paddlin’ out for. For the first two weeks, from Sunday 2nd August through to Saturday 15th August, every single session is marked as "poor surf conditions." The swell is tiny, mostly under 3 feet, and the wind is a constant cross-onshore from the NNW or NW. The water temp is sittin’ at 67°F, which is a bit colder than normal for this time of year, so you’ll want a decent suit.
The first real standout – and I use that term loosely – shows up on Sunday 16th August. The morning session at Cogumelo is the only time in the whole outlook that gets a flicker of life, with a "marginal" call. The swell is still small, around 4 feet comin’ from the NW with a period of 8 seconds, givin’ us a moderate wave energy (205). The wind finally swings to the west and goes straight onshore, which is clean but it’s not offshore. It’s not gonna be anythin’ special, but compared to the two weeks of junk before it, it’s the best we’ve got. The combined energy is moderate (205), so there’s a little bit of push, but it’s a short period swell, so expect it to be a bit fat and sectiony.
After that, Monday 17th August looks like it drops off completely, with no swell at all.
So, if you’re desperate for a paddle, the morning of Sunday 16th August at Cogumelo is your only shot. It’s a fairly consistent break, but it does get crowded often, so expect company. The rest of the window is a write-off. This is one of those stretches where the forecasts are more reliable for the near term, and unfortunately, the near term is flat. Long-range, that Sunday 16th is promising but not certain. Keep your eyes on it, but don’t hold your breath.
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.
