The Lowdown
G’day, Rusty here. Look, I’ll level with you: the next 16 days at Beliche are a real mixed bag, and for the most part, it’s a frustrating wait. The water is running *much colder than normal* for this time of year, sitting at 67°, so you’ll want a good 4/3 or a hood. There’s a big gap of quiet, small surf right through the first week, with nothing worth paddling out for until Saturday the 22nd of August, and even then it’s a bit touch-and-go.
The real standout shows up on Saturday the 22nd of August morning. Beliche (a beach and point setup, sheltered from the swell) gets a solid 7ft pulse from the NNW with moderate offshore winds from the NNW at 19 mph. The combined energy jumps to 496 (moderate wave energy), and while the period is a short 8 seconds, the offshore wind should keep it clean. This is a powerful, punchy wave for advanced surfers only – anything over 5ft is pushing it for beginners, and at 7ft, you need to know what you’re doing. The swell direction matches the optimum NW direction, so it’s hitting the spot right. Come Monday morning the 24th of August, it drops back to 6ft from the NNW, still with cross-offshore winds and clean faces, but it’s not the same punch – the energy drops to 374.
Later in the window, there’s a promising but less certain call for Friday the 28th of August morning. Another 6ft NW swell rolls in, but this time the period extends to 10 seconds, giving it more shape and grunt. The combined energy sits at 543 (moderate wave energy), and fresh offshore winds from the N at 22 mph should keep it glassy and lined up. That’s a good one for the experienced crew.
Saturday the 29th of August morning is also worth a mention: 5ft from the NW with a 10-second period, offshore winds from the NNW at 19 mph, and energy at 416. It’s a step down in size, but cleaner and more manageable for a strong intermediate.
The rest of the fortnight is a write-off. There are long stretches of tiny, weak waves, poor conditions, or just plain flat. The first week is a total blank – nothing until the 22nd – and then after the 29th, it fades back into knee-high mush. For the most part, this setup looks more interesting for kite surfing than paddle surfing through the middle of the window, when the wind is honking and the swell is messy.
The best of the best? Lock in the morning of Saturday the 22nd of August at Beliche for that 7ft offshore session. It’s the only true standout. The 28th of August is a close second if you like a longer period.
Stay salty,
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.
