The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cooking at Beliche. We’ve got a long stretch of days ahead, but honestly, it’s going to be a real mixed bag. The standout window doesn’t come until late in the second week, but when it arrives, it'll be worth the wait.
The Overall Picture
Right now and for the first week and a half, we’re looking at a lot of onshore-influenced swell and strong offshore winds that are actually too strong for comfortable surfing. The water’s a bit colder than usual for this time of year at 68°F, about 3°F off the norm, so you might want a thicker suit. The wave energy in the water is low to moderate to start, with values like 129 to 388 (moderate), building into the 500s and 700s (moderate to strong), but unfortunately the conditions don't match that energy until later.
The Long Grind (12–21 August)
From Wednesday the 12th through to about Monday the 17th, Beliche is essentially a no-go for decent waves. The swell is there, but it’s mostly short-period windswell (8–10 seconds) with cross-off or fresh offshore wind. The wind will be blowing 12–25 mph from the NNW, straight offshore, which sounds good, but it’s too strong – it’ll create a bumpy, difficult paddle and white-knuckle takeoffs. The ratings are zero across the board. After that, from Tuesday the 18th through Thursday the 21st, we get lighter winds, but they turn onshore or cross-onshore, making the surf sloppy and weak. Energy drops to as low as 110 (weak), which is just not worth paddling out for.
The Real Show (22–24 August)
Now, this is where it gets interesting. The pick of the whole 16 days falls on Saturday the 22nd and Sunday the 23rd of August. We’ve got a proper groundswell showing up from the NNW. On Saturday morning, the swell builds to 8 ft at 10 seconds from the NNW, with a massive combined energy of 1326 (strong). That’s big, powerful surf. The wind is a fresh cross-off from the NNW at 22 mph, which will keep things relatively clean but with some texture. At 8 ft+, this is strictly for experts – if you’re not confident, stay on the beach. This NW swell direction matches the spot’s optimum, so the waves should wrap in nicely.
Sunday morning the 23rd is also a standout: 7 ft at 9 seconds from the NW, with 734 energy (strong), and moderate offshore wind from the NNW at 16 mph. This is cleaner and a touch smaller, but still solid and powerful. The period is shorter than Saturday, but the offshore wind will hold the faces up nicely.
The Fade-Out (25–27 August)
After that, it quickly fades. Monday the 24th has 6 ft with a short 8-second period and light winds, but it’s marginal. By Tuesday the 25th, the wind cranks back up (19–25 mph offshore), making it ugly and hard to paddle. The energy drops to the 200s and 300s, and the wave heights are around 5–7 ft. The last couple of days (26th and 27th) are the same story: plenty of wind, not much usable wave.
Bottom Line
Don't bother with the first week. It’s either too windy or too weak. The only window worth your time is Saturday 22nd through Sunday 23rd of August, when we get that big, strong NW groundswell with manageable offshore winds. If you’re an expert and can handle 7–8 ft, that’s your moment. Otherwise, wait for the next system.
Stay safe out there.

Information about the Beliche Surf forecast
The above surf forecast table for Beliche provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Beliche can be found by selecting the local surf guide option on the grey menu. Our Beliche 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 (Beliche) 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 Beliche 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.
Beliche is 29 km (18 miles) from Lagos. If you plan a holiday in The Algarve, look for hotels and other accommodation in Lagos. Lagos has rooms for a wide range of budgets as well as car hire and transport links.
