The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Cogumelo.
Truth be told, it’s a bit of a slow start and the forecast is a long grind. The whole 16-day window is pretty much a write-off for decent paddle surfing. There’s no real standout session, and the bulk of the period is plagued by poor conditions. The water temperature is sitting at 67°, which is a bit colder than normal for this time of year – a full 3° below average, so you’ll want a good wetsuit.
We’re looking at a long gap of nothing worthwhile. The first few days, from Friday the 31st of July right through the weekend, have tiny, weak swell. The combined swell energy is low, barely hitting 130 (moderate at best) and the wind is mostly cross-on or cross-off, keeping things choppy and messy.
The first session that might raise an eyebrow is Saturday morning, the 1st of August. The swell is only 2ft from the W, but the period jumps to 9 seconds. The wind is light and cross-off from the NNE, which will keep the surface clean. The wave energy is moderate (125). It’s surfable, but very ordinary. The rest of that weekend and into the next week is all poor surf.
There’s a bit more energy building towards the second week, but it’s all onshore or cross-onshore wind. By the 8th of August, the swell is 4ft to 5ft from the WNW/NW, with periods around 9 seconds, and the energy is climbing to 316 (strong) on Saturday afternoon. But the wind is howling from the NW at 16 mph, making it choppy and lumpy. This pattern of moderate to strong swell but onshore wind continues right through to the 15th of August. On the 11th and 12th of August, there are mornings with light cross-shore winds from the N, but the swell is small and inconsistent.
Honestly, if you’re looking to get wet, Cogumelo is a tough call. The combo of short-period swell and cross-onshore winds means the setup looks more interesting for kite surfing than paddle surfing for most of this period. Don’t write it off completely, though; the energy is there, and if the wind shifts, it could clean up. But for now, it’s a waiting game.
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.
