The Lowdown

Alright, mates, Rusty here. Let’s break down what the ocean’s cooking up for Castelejo. The first week is a proper grind. We’ve got a long stretch of messy, wind-chopped surf. From the start, that north-northwest wind is smashing the coast, making everything a lumpy, blown-out mess. The swell’s got some size, about 4 ft to 5 ft on Monday and Tuesday, but it’s getting torn up by strong cross-onshore winds hitting 19 to 22 mph. This isn’t surf for a paddle board—honestly, it’s more of a kiteboarder’s playground. The water’s sitting at about 66°, which is a solid 5° colder than normal for this time of year, so you’ll be wanting a hooded 5/4. The wave energy is moderate, around 440 to 758 (combined energy), but it’s all wasted on these conditions. There’s nothing worth paddling out for until the end of the first week.

Now, for the first real chance. Friday, September 11th, the morning shapes up with a clean little 4 ft swell from the north-northwest, period around 9 seconds, and a light cross-offshore breeze from the east-southeast. That’ll put some clean lines in the water, and the energy is a modest 220 (combined energy). Friday afternoon, the wind dies to glassy, dead calm, with a 3 ft north-northwest swell. It’ll be buttery smooth. Friday morning is your best bet in the first week. The second week is a longer-range look, but there’s a real glimmer of hope. Sunday, September 21st, the morning looks fantastic. A light offshore breeze from the east-northeast, and a long-period 2 ft groundswell from the northwest at 12 seconds. The energy is 219 (combined energy). That’s small, but with that period and offshore wind, it’ll break like a dream on the reefs or points. Keep that Sunday morning window circled on your calendar—it’s the real standout of the whole forecast. Outside of that, the second week is mostly a write-off with cross-shore winds. Stay patient, and I’ll see you in the lineup. Rusty.

Information about the Castelejo Surf forecast

The above surf forecast table for Castelejo provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Castelejo can be found by selecting the local surf guide option on the grey menu. Our Castelejo 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 (Castelejo) 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 Castelejo 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.

Castelejo is 25 km (16 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.
