The Lowdown

Alright folks, Rusty here. Let’s talk about what’s on the menu at Castelejo.

Right now it’s looking pretty flat and ordinary for a spell, so don’t even bother waxing up just yet. The first real glimmer of hope doesn’t show until late in the week. The water temp here is 66°F – that’s a good 5°F colder than usual for this time of year, so you’ll want a good steamer.

We’ve got a serious wind problem through most of the first week. The north to north-northwest winds are mostly onshore or cross-onshore and that’s just wrecking any chance of quality. We finally get a break on Sunday the 13th in the afternoon with a glassy session. The swell is small at 3ft from the NW, but it’s got some real grunt with a 13-second period. The combined energy is a moderate 310 – not huge, but it’ll be clean and rideable. That’s a decent shout for a longboard or a funboard if you’re keen for a paddle.

Monday the 14th morning is also a good shout with a clean, cross-off ESE breeze. Swell bumps to 4ft from the NW with an 11-second period (315 combined energy). That’s your first proper window with shape.

Then it all goes a bit messy again until we get a standout window on Friday the 18th morning. That’s the one to circle on the calendar. We’ve got a clean 5ft NW swell, period of 10 seconds, and a light offshore from the SE. Combined energy is moderate at 388. The light offshore wind is going to groom the face, and with the reef setup here, that’s going to be the pick of the early period for a proper surf.

Later in the second week, things get very interesting. On Thursday the 25th morning, we’ve got a cracking forecast if you’re experienced. Swell size hits 4ft from the NW, but look at that period – 16 seconds of pure groundswell energy. The combined energy is a whopping 1311, which is strong. The wind is light cross-off from the ESE and it’s clean. That’s big, powerful, clean surf. This is a setup that is going to draw a lot of energy and will really shine on the reef sections, but be warned – that long period makes it tricky at beach breaks. For experienced surfers, this is the standout of the whole outlook. Expect crowds to be possible.

Friday 25th morning is the true stand-out. That’s the one for the chargers.

For the rest of the second week, there are some small clean windows on the 23rd and 24th, but the swell is pretty ordinary and the wind is howling on the 24th. Nothing to get excited about.

So, to sum it up: wait until Sunday the 13th for a glassy slow-wave session, Monday 14th morning for a fun clean wave, and then keep your powder dry for Friday the 18th morning. But the real big dog is Friday the 25th morning – that’s a session for the crew that knows what they’re doing. Everything else is a write-off or marginal.

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.
