The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for the next couple of weeks.
Honestly, the outlook is a tough one. We’ve got a long stretch of small, messy conditions at Cogumelo. The pattern is dominated by cross-onshore winds and weak, short-period swell, which means the waves are going to be pretty ordinary for most of the run. The combined energy readings are mostly low, often under 100, which tells you the ocean just isn't packing much punch.
There’s a gap of several days with no real surf to speak of. The first sign of anything worth getting out of bed for shows up on Wednesday morning, July 29th. The wind drops to glassy, calm conditions, and the swell is a tiny 2ft from the NW with a 9-second period. The combined energy is only 99, so it’s not going to have any power, but it’ll be clean. It’s a weak wave, but for a beginner or someone just wanting to get wet, it’s the best looking morning in the first week.
The next mention is Sunday morning, August 2nd. The wind is cross-offshore from the NNE at 6 mph, which cleans the surface up nicely. The swell is still small, 1.6ft from the west, with a 9-second period, and energy is weak at 62. It’s surfable, but you’ll be working for every ride.
Things get a little more interesting around Tuesday, August 5th, with a bump in the morning. The swell picks up to 3ft from the WNW, with a 10-second period, and the combined energy hits 163. The wind is a light cross-shore from the north, so the surface should be okay. This is probably the best of the first two weeks for actual wave shape, but the size is still modest.
Looking further out, the standout is Tuesday morning, August 11th. The swell is forecast to push up to 4ft from the WNW, with a 9-second period, and the combined energy jumps to 231. That’s a moderate energy level, the strongest in the whole run. The wind is light cross-onshore from the NNW at 9 mph, so it’s not perfect, but it’s the biggest, most energetic swell we see. This is your best bet for a proper wave, though it’s still within the beginner-friendly range. The Wednesday morning after that has a similar energy level at 245 with a slightly smaller 3ft swell, but the wind is unfortunately stronger and more cross-onshore, making it choppier.
Overall, the water temperature is about average for the time of year. The crowds at Cogumelo can be often, so expect some company if you do go out. For most of the 16 days, the waves are small, energy is low, and the wind is onshore. It’s a period for a longboard or a funboard, and you’ll have to pick your windows carefully. The best day to get excited about is that Tuesday, August 11th, but don’t expect a classic.

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.
