The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the table for our stretch of coast. We’re looking at a pretty lean start, but the back half of the run has some serious potential if you’re willing to wait.
The first proper recommendation pops up on Saturday, 22nd of August. Before that, from Monday the 17th through Friday the 21st, it’s mostly a write-off – poor surf conditions, choppy, cross-onshore winds, and tiny swell. A few days there with waves under 3ft and weak energy – you’d be fighting a losing battle. That’s a solid five-day gap with nothing worth paddling out for.
Saturday the 22nd is where it starts to get interesting. Beliche (beach and point) is the only game in town, and early morning is your window. We’ve got a clean 5ft swell from the NNW, with a gentle offshore wind – that’s calm, clean conditions with the wind blowing right into the face of the wave. The combined energy is moderate at 434 – enough to push you in, but not so much it’s a battle. The swell period is 9 seconds, a solid little groundswell that’ll offer some shape on the point. This is a sheltered spot, so it’ll concentrate that NW swell nicely. It’s a fairly consistent break, but it can get crowded often, so expect company if you’re heading out.
The standout, though, is the end of the window. Mark your calendars for Saturday, 29th of August, and Sunday, 30th of August. Saturday morning we’ve got a 7ft swell from the NW, period 10 seconds, and a fresh offshore wind. The combined energy jumps to 881 – strong, powerful stuff. That’s a solid, powerful wave. It’s a bit on the bigger side, so this one’s for the experienced crew. Sunday morning is even heftier: 8ft from the NW, 10-second period, offshore wind, and combined energy roaring into four digits at 1026. That’s serious wave energy. The water temperature is about average for this time of year, so nothing unusual there.
Then, on Tuesday, 1st of September, we get a very long-period groundswell – 15 seconds – from the NW, with a 6ft swell and a fresh offshore wind. The energy is massive at 1720, but that long period will make the waves a bit more lined up and powerful. At a point break like Beliche, that’s a dream scenario. However, it’s a long way out, so while the potential is huge, don’t set your watch by it just yet.
So, to sum it up: the first week is a bust. Saturday the 22nd is a nice little warm-up if you’re desperate. But the real gold is the last weekend of August and into September – that’s when the big, clean, offshore swells roll in. Strong, powerful, and clean. Get ready.
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.
