The Lowdown
Alright folks, Rusty here. Let’s break it down.
We’ve got a slow start on the cards at Beliche. The first few days are a bit of a write-off, with poor surf and solid onshore winds, but things do start to look up later.
The water is sitting at 68° and it’s a bit colder than normal for this time of year, so don’t be fooled by the sun. You’ll want a good wetsuit for the first few days.
We’re looking at a pretty long gap of ordinary to poor surf from the 9th right through to the 20th. The swell is there, but it’s mostly small, short-period stuff and the wind is often messy. The combined energy is weak to moderate, with values mostly in the low to mid hundreds, but the quality just isn’t there. The best of that first week is probably the glassy moments on Saturday afternoon, the 12th, and Sunday afternoon, the 13th, when the wind drops right off and the swell gets a bit of a longer period (13-14 seconds), but it’s still small. There’s a glimmer of something better on the 14th, but the wind isn’t perfect.
The real standout, and the one to circle on your calendar, is Monday the 21st of September. That’s our big window. The swell jumps up to 8ft to 10ft from the NNW, with a combined energy in the thousands, which is proper strong. This is a powerful swell with a moderate period, so it’s got some punch. The wind is light and clean, which is a major positive. That’s expert territory, though – over 8ft is for the experienced crew. It’s going to be a cracker, but crowds are likely.
The rest of the second week cleans up nicely after that. The 22nd drops off a bit with cross-onshore wind, but from the 23rd to the 24th, we get a nice, clean, moderate NW swell (5ft to 5ft) with a solid 11-second period and light offshore winds. That’s your sweet spot for the average surfer – clean, fun, and a lot more manageable. The combined energy is still strong, so there’s plenty of grunt.
So, the plan: Wait out the first week, it’s a bit of a dud. The 21st is the big one for the experts. The 23rd and 24th are the best all-round days for a good, clean surf.
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.
