The Lowdown

Alright folks, Rusty here. Let’s take a good, hard look at what Castelejo has in store for us over the next couple of weeks. There’s a bit of a slow start, but there’s a little light at the end of the tunnel if you can be patient.

Right off the bat, things are looking pretty ordinary. We’ve got a few days of small, messy surf to work through. The water is running at 67°, which is about 4° colder than usual for this time of year, so you’ll want a decent 4/3.

We start the period on Wednesday, September 2nd with a weak 4ft NW swell and a short period of 8 seconds. The combined energy is a low 205 (weak), and with a cross-on NNW wind at 12 mph, it’s just choppy and poor.

Thursday the 3rd is a bit better, but only marginally. The morning sees 3ft NW swell, period of 7 seconds, with an ESE wind at just 3 mph blowing cross-off. It’s clean, but the wave energy is a paltry 94 (very weak). The afternoon cleans up even more with a light offshore SE breeze at 9 mph, dropping the swell to 2ft. It’s surfable, but so small it’s barely a wave.

Friday the 4th through to Wednesday the 9th is a real write-off. We get a steadier pulse of NW swell, but the wind locks in from the north and northwest at 12 to 25 mph, which is a constant cross-on to onshore. Even though the swell height builds from 2ft to 8ft, the period is short (8-10 seconds) and the energy jumps from 91 up to 787 (moderate), the wind is just trashing it. It’s lumpy, choppy, and messy – no good for a paddle. Honestly, with that and a beach and reef setup, this looks way more interesting for kite surfing than a regular session.

We get a slight break on Saturday the 12th. The morning is still poor with a tiny 2ft NNW swell, but by the afternoon, the wind goes completely glassy. The waves drop to a tiny 2ft with a 6-second period and a combined energy of just 42 (very weak). It’s glassy and clean, but there’s hardly any push.

Now, here’s where it gets interesting for the patient few. The real standout of the entire forecast is Monday, September 14th, early. A fresh NW groundswell rolls in overnight. We’re looking at 3ft of swell at 15 seconds (very long period) and a combined energy of 860 (strong). The wind goes glassy with a light SE breeze. This is going to be clean and lined-up, but with that long period and a beach and reef setup, it will be breaking a bit straight and fat on the beach sections. Get to the edges or the reef points for the better lines.

That swell builds for Tuesday the 15th morning. We get a solid 6ft NW groundswell with a 13-second period, energy of 1021 (strong), and a light offshore ESE breeze at 6 mph. This is excellent for experienced surfers—the water will be clean, the waves will have real punch, and the long gaps between sets will make paddling out a bit easier. The size means it’s probably too much for beginners, though.

After that, the window closes. From Wednesday the 16th onward, the wind swings back onshore and cross-on, smashing the leftovers of the swell into a messy, blown-out mess. The energy drops back into the 100s (weak to moderate) and the quality is gone.

If you’ve got the time, the absolute stand-out is the glassy, long-period NW swell on the morning of Monday the 14th. The Tuesday morning, the 15th, is a close second with more size but a little more wind. Everything before that is a waiting game.

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.
