The Lowdown

Alright folks, Rusty here. Gotta be straight with you – the next couple of weeks look pretty grim for most of us. The swell is on offer, but it’s almost always coming with onshore or cross-onshore winds that are just going to chop it up. We’re looking at a long stretch of poor surf conditions, so don’t get your hopes up too early.

Let’s start with the only spot on the cards: Castelejo. The water is sitting at 67° which is a bit colder than normal for this time of year, so you’ll want a good wetsuit.

The first real chance of anything decent doesn’t appear until Saturday the 15th of August. The swell picks up to 5ft coming from the NW with a period of 8 seconds, and the combined energy is moderate (306). But the wind is a cross-on moderate breeze, which will leave it choppy. Not great, but it’s something.

Sunday the 16th sees similar size (5ft NW) with a gentler cross-on breeze, but the energy is getting stronger (386). Still, it’s only going to be fairly choppy. The Monday morning of the 17th might be your best bet early on – the wind drops to a light breeze and goes straight offshore from the NW, with a 4ft NW swell (189 energy). That could actually be clean for a few hours. It’s not a standout, but it’s the closest we get to a decent paddle.

Then we fade out again until the 21st of August. That Friday morning shows a 7ft NW swell with a period of 9 seconds and a massive jump in energy (720). The wind is a light cross-on from the W, which is just about manageable. This is the biggest swell of the window, but it’s a bit of a beast – over 6ft, so it’s really only for the experienced crew. The conditions are described as “marginal,” so it’s a gamble. The afternoon of the 21st stays similar (770 energy) but with a gentle cross-on breeze, still marginal.

After that, the 22nd and 23rd see the wind pick up hard again, with strong breezes and messy conditions. The swell stays around 6ft to 7ft, but it’s all blown out.

The standout? Honestly, there’s no true gem here. If I had to pick one, it’s the Monday morning of the 17th of August. The offshore wind and clean lines from a NW swell at 4ft is the best compromise we get. It’s not big, but it’ll be clean. For the more experienced, keep an eye on the 21st of August. That big NW swell (7ft) has the energy, but it’s a long way out and the wind is a cross-on, so it’s a gamble.

For the rest of the time, the setup is more interesting for kite surfing than paddle surfing. The beach-and-reef break is exposed to the NW swell, but the constant onshore winds just make it a mess for us.

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.
