The Lowdown
Alright folks, Rusty here. Let's cut the chatter and look at the surf ahead for our coast. The short version is this: the next week and a half is going to test your patience. We’ve got a long, flat, and messy run of small, weak waves with poor winds for the most part. But hang tight, because the back half of this forecast window is where things get properly interesting. There’s a serious pulse of NW groundswell lining up, and if it connects, we’re in for a proper session.
The early outlook is grim. From the 15th through to the 28th, we’re looking at a whole lot of nothing special. Swell heights will be struggling, mostly in the 1.6ft to 5.5ft range, with the energy being weak to moderate at best (energy values mostly between 58 and 500). The wind is the real killer here, though. For the first few days, it’s cross-onshore or just messy, making for choppy, poor conditions. There's a brief window on the morning of the 21st with a moderate offshore (NNW) and clean waves at 3.6ft, but it's not enough to get excited about. The 22nd and 23rd have some clean surfaces but the swell is still weak and short-period, just not worth the paddle.
There’s a little bump around the 24th and 25th, with chest-high swell (5.2ft - 5.6ft) and clean conditions, but the short, 8-second period means it's going to be a bit crumbly and without much push. The 29th is when the alarm bells should start ringing. We finally see a real jump in size and energy. The energy readings go from weak to strong very quickly (799 on the 29th morning), and the swell is building from the NW. By the afternoon of the 29th, we're looking at 9.8ft of swell with the energy climbing into the very strong range (1197). This is a proper swell.
The standout of the whole period, though, is the morning of the 30th. The swell is a solid 9.8ft from the NW, with a longer period of 10 seconds, and the energy readings are at a massive 1686. That's a lot of moving water. The winds are light (9 mph) and cross-off, which should keep it reasonably clean. This is the one to circle on the calendar. At this size, it's strictly for experienced surfers – this is not a day for the learners. The water temperature is running about two and a half degrees Fahrenheit colder than normal for this time of year, so you’ll want the full wetsuit.
So, the plan is simple: skip the groveling sessions this week. Wait for that big pulse on the 29th and 30th. It’s looking like the real deal, though we’re still a week out, so let’s keep our fingers crossed on the winds. See you in the water.

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.
