The Lowdown
Alright, let’s get to it. This is Rusty, and we’re looking at the stretch ahead for Beliche (Algarve). It’s a bit of a slow burner, but there’s some life in it if you know where to look.
For the next few days, the surf is going to be pretty unconvincing. The swell is small and the wind is blowing hard out of the north, which keeps things clean but the waves are just too weak and ordinary to get excited about. We’ve got a couple of days of this low-energy stuff, with the swell energy sitting in the low to mid 100s (174 to 270). It’s surfable, but you’ll be working for every wave and it’s not going to be memorable.
The first real glimpse of something better shows up on the morning of Sunday the 16th. The swell bumps up to a solid 7ft from the NNW, with a moderate offshore wind and the energy jumps to 618. That’s the first time it feels like the ocean wakes up. It’s still a bit fresh, but the sets will have some push to them. The afternoon stays decent, but the wind swings a little more cross-off. Still, this is the first day that’s worth paddling out for.
There’s a bit of a lull again on Monday and Tuesday, with the wind turning onshore and the swell dropping right back. The energy falls to around 175 to 181, and it’s not worth your time. Wednesday the 19th is even worse, with the swell down to under 3ft and the energy bottoming out at 91. That's a real dry spell.
Now, for the standout. Thursday the 20th looks like the pick of the whole run. The early morning is glassy with no wind at all, and there’s a heavy groundswell coming from the NW at 3ft, but with a long 12-second period. That’s clean, lined-up, and the energy is picking back up to 306. The afternoon sees the size jump to 5ft with an 11-second period and energy at 606, but the wind gets a bit cross-shore. The morning session is where it’s at. That’s the one to circle.
After that, we’ve got a run of fresh offshore winds from Friday the 21st and into the 22nd, keeping it clean but the swell is a bit messier and the energy is moderate. The 21st has a 6ft swell but the period drops back to 9 seconds, so it’s less well-ordered. The next few days after that are all pretty similar – surfable, clean, but nothing that’s going to blow you away. The swell slowly fades out through the end of the period, with the energy dropping back down to the low 100s and 200s by the 24th through the 27th.
There’s a little bump on the 25th with a 5ft NW swell and 9-second period, but the wind is cross-off and it’s just okay. The 27th has a similar vibe, but it’s all just average. The real magic is the glassy morning of the 20th. Get it while it’s there.
The water temp is about average for this time of year, so no surprises there. Beliche is a beach and point setup, so when that long-period groundswell hits on the 20th, it’s going to offer some better lines along the point. Just be aware that the long period can make the beach break sections a bit straight, but the point should handle it well.
So, to sum it up: the next few days are for the patient, Sunday the 16th gives you a taste, but Thursday the 20th is the one. It’s a while out, so treat it as promising, not guaranteed, but the signs are good. After that, it’s a slow fade with a few average days. Keep your eyes on that Thursday morning.
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.
