The Lowdown
Alright, Rusty here. Let’s talk about what we’ve got lined up for Beliche.
First up, water temps are running a bit colder than normal for this time of year, sitting at about 67°. That’s a noticeable chill in the air, so you might want a spring suit.
Honestly, the next week or so is pretty grim. We’ve got a long stretch of nothing much happening. From Monday the 17th right through to around Thursday the 20th, it’s mostly small, weak, and choppy. The swell energy is low, barely hitting triple digits, and the wind is all wrong—cross-on or onshore most of the time. Not worth paddling out for.
The first real glimmer comes Friday the 21st morning. The swell bumps up to about 6ft from the NW, with a bit more punch. The combined energy jumps to 431 (moderate), and the wind turns cross-off, keeping things clean. It’s still only a 1 out of 10 on quality, so it’s more of a “get wet if you’re desperate” kind of session. The period is short at 8 seconds, so don’t expect much shape.
Saturday the 22nd morning is worth a look. We get about 5ft from the NNW with offshore winds (12 mph) and combined energy at 340. The wind is offshore and clean, so the surface will be tidy. Still, the waves are ordinary—nothing to write home about.
The standout window arrives on Saturday the 29th of August. That morning is pure glass: about 7ft from the NW, with the combined swell energy hitting 990 (strong). The wind is glassy, and while the size is pushing into expert territory (over 7ft), it’s clean and powerful. This is the morning to be there if you’ve got the skill. The period is 10 seconds—solid groundswell, but not overly long.
Sunday the 30th morning also shows promise with about 7ft from the NNW, period stretching to 11 seconds, and combined energy at a massive 1659 (very strong). The offshore wind is moderate and clean. That’s a big, powerful swell with longer gaps between sets, which helps with paddling out. Again, expert-only territory due to size, but if you’re charging, this is the highlight of the whole outlook.
Towards the 1st of September, we see another pulse of strong swell (about 7 to 8ft) from the NW with very long period (11 seconds) and very strong energy (over 1300). However, the wind is howling at 25 mph—strong offshore, which cleans it up but makes paddling a real battle. Only for the fittest and most experienced.
Overall, the best bet across the whole 16 days is Saturday 29th August morning, with Sunday 30th morning a close second. Everything before that is flat or mediocre.
Rusty signing off.

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.
