The Lowdown
Alright, let’s get into it. It’s been a bit quiet out there, and honestly, this stretch is going to test your patience. We’ve got a solid week-plus of tiny, weak surf ahead. The first real glimmer of anything rideable shows up on the morning of the 10th, but it’s marginal at best. Don’t get too excited. The energy is just anemic for days after that – a real dry spell.
We’re looking at Beliche (Algarve) as the only game in town. The water’s running about 67°F, which is a couple of degrees colder than you’d expect for this time of year, so grab the thicker suit. The opening days are all about small, weak swell. The 10th has a little 3ft to 3ft NW swell with a clean, offshore breeze in the morning, but it’s just not doing much. The 11th and 12th drop off badly with almost nothing. The 13th and 14th are still poor, with a bit more swell but still under 3ft and not offering any real shape.
The first time it feels like it might turn on is the morning of the 16th. We finally see a pulse to 5ft from the NW, and it’s dead glassy. That’s the first moment worth paddling out, even if it’s only just surfable. The combined energy is still moderate at 298, but it’s something. After that, the swell tries to build but the wind gets shifty and messy. The 17th gets cross-onshore and lumpy, and while there’s a bit more size on the 21st and 22nd, the wind is all over the place.
The standout window is the 24th. The swell is up to 6ft to 6ft from the NNW, with a period of 8 seconds. The combined energy jumps to a strong 621 by the afternoon. The wind is cross-offshore, keeping it reasonably clean. This is the best offer in the whole period. It’s still not a classic, but it’s the most powerful and organized we’ll see. The 25th still has some size, but the wind turns onshore in the afternoon, killing the vibe.
For the whole second week, just keep your expectations low. The 23rd has some size but rough winds. The 24th is the one to circle on the calendar. It’s promising, but given it’s a week and a half out, treat it as a hopeful possibility rather than a certainty. Everything before that is a beach day, not a surf 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.
