The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s shaping up at Cogumelo over the next couple of weeks. We’ve got a bit of a slow start, so if you’re itching for a paddle, hold your horses. The first few days are a write-off with strong, lumpy cross-onshore winds, so don’t bother until things settle.

The real action kicks off on the morning of Thursday the 17th. It’s still a bit raw with a 8ft NW swell and a cross-off breeze keeping it clean, but the energy is solid (1,061). Friday the 18th morning is where we start to see the first genuine standout. The swell drops a touch to 6ft from the NW, but a light cross-off breeze from the NNE will have it looking clean. The wave energy is moderate (576), and it’s a proper surfable morning.

Now, circle Saturday the 19th morning on your calendar. That’s the pick of the first week. Glassy conditions, a slight air, and a solid 6ft NW swell with a very long period of 14 seconds. The energy is pumping (1,372), and those long-period lines will march in with plenty of shape. This is a day for experienced surfers, but if you’ve got the skills, it’ll be worth the paddle out.

Sunday the 20th morning is also a good shout, with a clean offshore breeze from the ENE dropping the swell to a more user-friendly 5ft. That 12-second period still has plenty of push, and the energy is moderate (537). It’s a nice, clean option for a range of abilities.

Things get smaller and a bit inconsistent through the middle of the week, but we’ve got another glassy morning on Wednesday the 23rd September. That 5ft swell has a very long 15-second period, and the energy is strong (1,273). It’s a morning for the experienced crew again, as those long-period waves might jack up a bit, but the conditions will be pristine with no wind.

The following Thursday morning the 24th is another glassy start, with a 5ft NW swell at 13 seconds. Clean, calm, and a solid moderate energy (746). It’s a good session before the winds pick up later.

Heading into the final weekend, there’s a drop-off in size, but we’ve got one more promising morning on Tuesday the 29th September. A 6ft NW swell with a 13-second period, clean with a cross-off breeze from the NNE, and the energy is strong (1,210). That’s your long-range standout – a bit of a wait, but it’s got the makings of a ripper morning for those who can handle the size.

Overall, Cogumelo delivers a few choice windows. The absolute best on offer is that glassy Saturday the 19th, followed closely by the clean, offshore Sunday the 20th. For the later session, keep an eye on Tuesday the 29th. The rest of the time, the wind’s a bit of a pest, but we’ve got enough clean pockets to keep the stoke alive.

Stay safe, catch you in the water.
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.
