The Lowdown

Alright, grab your board and wax, let's talk about Castelejo.

Right off the bat, I gotta be straight with you – this 16-day window is a real test of patience. For the next ten days or so, Castelejo is pretty much a write-off. The winds are cruel, mostly onshore or cross-onshore, and the swell is small and weak with periods that just don't have any grunt. We're talking a lot of nothing, to be honest. This stretch runs from now all the way through to the 21st. It's a long, quiet spell. The water temperature is sitting at 67° and that's 4° colder than usual, so it's definitely feeling more like late autumn than summer.

The wait finally looks like it pays off on Saturday the 22nd. For the morning session, we get a gentle offshore breeze from the ESE and a clean 5ft swell from the NNW (299). Now, the period is a bit short at 7 seconds, so the waves will be a little lumpy and soft, but it will be rideable and clean. That's the first real window of opportunity. After that, the rest of the day gets messy again.

The next day, Sunday the 23rd, is where things get seriously interesting. The morning is looking like one of the best calls of the whole forecast. That WNW swell builds and the period jumps to a lovely long 12 seconds, pushing through with strong energy (929). We’ll see clean, well-shaped waves around the 4ft mark, and the wind is a gentle cross-offshore breeze from the ENE. This is a proper groundswell, and for a spot like Castelejo, which is a beach and reef setup, that long period should produce some really nice lines. It's the standout morning of the whole outlook.

Then we hit Monday the 24th. The morning is for experienced surfers only – the swell pumps up to 7ft from the NW with huge energy (1625). That's a lot of water moving, and the period drops back to 9 seconds, making it a bit of a lumpy beast. The winds are light and clean, so the heavy crew will have some serious walls to play with. The afternoon drops away into a messy, cross-shore wind situation, so don't sleep on that morning session.

After that, Tuesday the 25th morning offers a little glassy cleanup with a 3ft, 11-second swell from the WNW and a glassy wind. It's a nice little recovery, but the fun fades out again by the afternoon.

So, to wrap it up: the first week and a half is a total dud. Your best bets are the clean Saturday morning on the 22nd for a small-wave session, and then the absolute standout is Sunday the 23rd morning. If you have any flexibility, that's the morning to circle on the calendar.

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.
