The Lowdown
Right folks, Rusty here. Let’s talk about what’s on offer for the next couple of weeks at Beliche. This is a sheltered beach and point set-up, so it’s a picky spot, but when it locks in, it can be real special. Water temps are sitting at 66°, which is about 5° colder than usual for this time of year – that’s a notable chill in the water, you’ll want a decent suit.
Alright, the start of the outlook is a bit of a slow burner. We’re kicking off Tuesday the 15th with small stuff. Morning has clean 2ft waves from the NW with a moderate offshore breeze, but it’s weak (combined energy of 101). The afternoon gets a little bumpier with 4ft from the NNW but the wind picks up to 22 mph, making it messy. Not worth paddling out for.
Wednesday the 16th the swell jumps up, but the wind is a beast. Morning has 8ft from the NW with a strong offshore at 28 mph – that’s a battle just to get out. Afternoon sees 8ft from the NW and cross-off wind at 25 mph. The size is there (combined energy up to 1126) but it’s one for the experts only, and honestly, the wind makes it a chore.
Thursday the 17th, similar story: 8ft from the NW in the morning and 8ft in the afternoon. The wind is still fresh at 19 mph. The energy is heavy (1446 in the morning) but the conditions are marginal. It’s big and wind-affected. This is kite-surfing territory if you ask me.
Friday the 18th is where we start to see a glimmer. Morning has a clean 7ft from the NW with a moderate offshore, and the energy is moderate at 777. It’s still a bigger wave, but the wind is easing off. The afternoon drops to 6ft with cross-off breeze.
Now, Saturday the 19th is the first real standout for the window. The afternoon session is the pick: 6ft from the NW, but the period stretches out to a lovely 14 seconds. That’s proper groundswell energy (1367), and with a light NE breeze (6 mph) coming cross-off, it’s clean. This will line up nicely on the point. The morning is a little wind-affected from the ESE cross, but the afternoon is the one to aim for.
Sunday the 20th and Monday the 21st are a drop-off. We get small 5ft and 4ft waves with cross-shore winds and chop. Not great.
Then we get a window of calm. Tuesday the 22nd morning is completely glassy with 4ft from the NW – no wind at all. The energy is 318. It’s surfable, but small.
Now, Wednesday the 23rd is the other standout. The morning session is glassy again, zero wind, with 6ft of swell from the NW at a 14-second period. The combined energy is a solid 1263. That is clean, lined-up, and punchy. For a sheltered spot like Beliche, this is the best on offer. The afternoon has a light cross-breeze so it won’t be as tidy.
After that, Thursday the 24th keeps going with 5ft in the morning and a light N offshore, and 4ft in the afternoon, both with clean conditions. The energy is moderate (624 and 527). Good, fun, solid surf.
The rest of the window fades off into smaller, windier sets, with a final mention for Wednesday the 30th morning which goes glassy again with 4ft from the NNW and a 10-second period. Energy is 499. Worth a paddle if you’re around.
So to wrap it up: the best days are Saturday the 19th afternoon and Wednesday the 23rd morning. The 23rd is the pick of the whole run – glassy, long period groundswell, and clean offshore winds. Get on 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.
