The Lowdown
Alright folks, Rusty here. Let’s have a look at the forecast for Beliche. It’s a bit of a mixed bag over the next couple of weeks, with a lot of ordinary conditions to wade through before we get to anything worth paddling out for.
Right off the bat, the water is running a bit colder than normal for this time of year, sitting at 67°F at Beliche. That’s a couple of degrees off the usual, so you might want a thicker suit.
The first few days are pretty grim. We’ve got a run of "poor surf conditions" with a score of zero from Monday afternoon right through to the end of the first week. The swell is tiny, mostly under 3 ft, with a short period of 8 seconds or less. That’s weak, choppy stuff. The wind is mostly offshore or cross-off, which would normally be a good thing, but with the combined energy of all swells directed here barely cracking 100 (101) at the start, there’s just no push in the water. It’s a flat spell, and you’re better off saving your energy.
We’ll see a minor bump in energy mid-week, around Wednesday the 12th and Thursday the 13th, with the combined energy climbing to 125 and 158, but the conditions are still described as "very ordinary." The swell stays around 3 ft to 3 ft, with a period of 10 seconds from the WNW. The wind stays offshore, but the surf quality is just not there. It’s a frustrating few days, honestly.
The weekend of the 15th and 16th sees the swell push up a notch, hitting 4 ft to 5 ft, and the combined energy jumps into the 300s (300, 323, 372). The period is still short, though, around 8 seconds from the NW. The wind turns cross-off, and while the surf is clean, it’s still rated as poor. It’s a bit of a tease—more size, but no real quality.
There’s a gap of a few days here where the conditions are just not good enough to recommend. The energy drops off again, and the swell stays small and messy.
The one standout, and the only time I’d get excited, is looking way out to the end of the forecast. On Monday morning, August 25th, the stars finally line up. The wind is a slight offshore breeze from the NNW, which is glassy and clean. The swell is 4 ft from the WNW with a period of 11 seconds. That’s a proper groundswell, with good energy (combined energy of 528). The conditions are described as "expect good surf conditions," and that’s the only 2 out of 10 score in the whole run. This is the one to circle on the calendar. It’s a long way off, so take it with a grain of salt, but it’s the best bet on offer. The break is a beach and point setup, sheltered from the main swell, and the optimum direction is NW, so this WNW swell is a good match.
Before that, on Sunday, August 24th, the swell is bigger at 7 ft from the NW with a period of 9 seconds, but the wind is onshore from the SSE. That’s a messy, blown-out situation, and the combined energy goes through the roof to 1694, but it’s just too big and wonky for a clean paddle. That one’s for the experts only, if anyone’s brave enough.
So, the summary: the first week is a write-off. Second week has a few days with more size but no quality. The only real standout is the morning of the 25th, with clean, offshore winds and a solid, long-period swell. It’s a long wait, but it might just be worth it.
Rusty.

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.
