The Lowdown
Alright, let’s get into it. This is your local surf outlook for the next 16 days. I’m only looking at what’s happening here, no comparing to other spots.
Let’s be straight with you. The forecast for Beliche is a bit of a mixed bag. It’s a sheltered beach and point setup, and it’s an advanced wave, so it’s not for the faint of heart anyway. The water temperature is sitting at 68°F, which is a bit colder than normal for this time of year.
We’re starting off with a real slow burn. The first real good window doesn’t show up until Sunday the 16th of August. The early part of the week is a write-off for any decent surf. Tuesday the 11th through Saturday the 15th is all small, weak, and mostly poor surf conditions. The energy is just not there. We’re seeing weak swell energy (48 to 585) with short, choppy periods. The wind is mostly offshore, which is good for the face, but the swell is just too small and weak to get excited about. It’s a frustrating stretch.
Then, things start to turn around on Sunday the 16th. The morning is still a bit marginal, but the afternoon picks up. We get a solid 6 ft swell from the NW with a 9 second period, and the combined energy jumps to 608 (moderate). The wind is light and cross-offshore, making for clean conditions. This is the first real standout of the outlook. The water is still a bit cold, but the surf is getting good.
The next few days are a bit messy again with onshore winds and poor surf. Monday the 17th and Tuesday the 18th are a write-off. But then, we get a promising run starting Thursday the 20th of August. The morning is looking good: 8 ft of NW swell, 9 second period, and a gentle cross-offshore breeze. The combined energy is a solid 905 (moderate to strong). This is a good, clean swell. It’s getting a bit bigger, so it’s for the more experienced surfers.
Friday the 21st of August is another one to circle. Morning sees 8 ft from the NW with a 10 second period. The energy is strong at 1483. The wind is a moderate offshore from the NNW, keeping it clean. This is a powerful swell, and it’s running right into the optimum NW direction for Beliche. This is probably the best the forecast has to offer, but it’s into the second week, so keep that in mind.
The weekend after that (Saturday 22nd, Sunday 23rd) is a bit on the bigger side with strong winds, making it a bit of a challenge. Then Monday the 24th of August brings another clean window with 8 ft from the NNW and moderate offshore winds. The energy is still strong at 753. The wind is improving, and the surf is good.
The very end of the outlook, into Wednesday the 26th of August, has another big pulse of 8 ft from the NW with a 9 second period and fresh offshore winds. The energy is very strong at 1474. This is another promising one, but it’s far out, so treat it as a hopeful sign.
Overall, the best bets are the afternoon of Sunday the 16th, and then the mornings of Thursday the 20th, Friday the 21st, and Monday the 24th of August. The 21st and 26th have the biggest swell, but it’s for the advanced crew. The 20th and 24th are a bit more manageable. The wind is mostly good when the swell shows up, so the waves should be clean.

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.
