The Lowdown
Alright, folks, let's get into it for the Beliche area. Rusty here, and I'll tell you straight up – it's a tale of two weeks, with a lot of waiting for the wind and swell to get their act together.
We're starting off slow. The water is about 68°, which is a bit cooler than usual for this time of year, so you might want a steamer. The first few days are a write-off with small, weak swell and onshore breezes.
The first proper chance comes on the 21st of August. Friday morning has a fresh 19 mph offshore wind from the north, cleaning up a 5ft swell from the northwest. The energy is moderate (348), but with that short period, the waves won't be the best. This spot is "fairly consistent" but crowds are "often", so expect company.
The next one to look at is Saturday morning, the 22nd of August. A moderate 16 mph offshore wind from the north-northwest, with a similar 5ft swell from the north-northwest. The energy is stronger (534), which is promising. It's the best bet in the first week, but still a "marginal" call.
Then we hit a dry spell. Sunday the 23rd is glassy but tiny, and then we have a long run of ordinary days until the end of the month.
The real standout is Monday the 31st of August. The morning is looking clean with a 5ft northwesterly swell, a light breeze, and moderate energy (404). This is the only day in the whole 16-day window that gets a "good" rating. It's the one to circle on the calendar, but expect a crowd.
The start of September also has some potential. The 1st of September has a clean 5ft northwesterly swell with a fresh offshore wind, but it's still a "marginal" call. The 2nd and 3rd have similar setups, but the wind gets stronger and the quality fades.
So, to sum it up: a lot of waiting, a few marginal days, and one clear winner on the 31st of August. That's your day.

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.
