The Lowdown
Alright, crew, Rusty here, looking at the next couple weeks for Beliche. We're in for a slow start, so be patient.
First, the water is running a bit cold, about 4°F below normal. That's worth remembering when you're picking your rubber. The opening stretch is looking flat with weak, jumbled surf and poor conditions. Just leave the board in the car for those first few days.
We pick up a little more size mid-week, with waves around 5 feet on Wednesday the 22nd, but the energy is still a bit weak. It's clean with the offshore winds, but the wave shape will be poor. It's a paddle-around session, not a world-class one.
By the 29th, we'll see some punchy 5-foot waves, but the wind is howling. At 45 km/h, the paddle-out will be a mission. This is one for the experts, and even they might struggle.
The first real highlight is Monday, August 31st. We have a solid 6-foot groundswell hitting the coast with light offshore winds in the morning. This will be the cleanest we've seen the place, with decent energy (516). This is your best bet for a proper surf.
Then, we have the final window. On Tuesday, September 1st, we see a good 4- to 6-foot NW swell, and the energy is really starting to pump. With light winds and clean conditions, this looks like the pick of the bunch. It's a long way out, so it's not a lock, but it's got real potential. A quiet week, but it could end with a bang. Stoke for that.
Rusty out.

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.
