The Lowdown
Alright, groms, Rusty here. Let’s talk about Cogumelo, the only spot on the menu.
Honestly, the next ten days look like a total flat spell. The swell is tiny, the wind is mostly rubbish, and the wave energy is weak. We’ve got a long wait for anything decent.
From Saturday the 18th right through to Tuesday morning the 28th, there’s nothing to ride. The swell height barely gets over 3 feet, the period is short, and the wind is always side or sideshore, chopping it up. The combined energy is low, mostly under 100 (weak energy). It’s just poor surf conditions, day after day. If you’re into kiting, the wind might be there, but for a paddle board, it’s a total bust.
The first flicker of hope comes Tuesday morning the 28th. The wind is light and cross-offshore from the NE at 3 mph, and the period jumps to 13 seconds. That’s a long period groundswell. But the swell is tiny, just 0.3 ft, so the energy is only 11 (weak energy). The surface might be clean, but there’s nothing to catch.
Now, the real standout is shaping up for the morning of Wednesday the 29th of July. The swell jumps to 6 ft from the NW, with a 9-second period. The wind is light from the NNW at 6 mph, which is a cross direction, creating light cross-shore ripples. The combined energy hits 516 (moderate wave energy), which is the first real sign of life. It’s a marginal call, but it’s the first decent energy in the whole window.
But the absolute best, the one you want to clear your schedule for, is the morning of Thursday the 30th of July. The wind is offshore from the E at 10 mph, and the swell is still a solid 6 ft from the NW, with a 9-second period. The combined energy is 564 (moderate wave energy). The forecast says “expect very good surf conditions.” That’s clean, offshore winds and a solid 6 ft swell. This is the one. For intermediate surfers, this is prime. The swell direction is NW, which is well within the optimum SW direction for this spot. The water is about 69°F, which is normal for the time of year.
The 31st of July morning is also a good backup, with a solid 5 ft from the NW, a 9-second period, and a light cross-offshore breeze from the SSE at 3 mph. The energy is 396 (moderate wave energy), and it’s clean.
After that, the 1st of August looks flat and glassy in the morning, then a big, messy 8 ft combo on the 2nd of August morning with a 10-second period from the NW and a cross wind from the S. That’s a powerful 1365 (strong wave energy), but with the wind and size, it’s only for experts and could be a mess.
To wrap it up: the long wait until the 29th of July is a drag, but the morning of the 30th of July is the clear winner. Get out there for that clean, chest-to-head-high NW swell.
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.
