The Lowdown

Alright folks, Rusty here, checking in on the local surf scene. We've got a long stretch ahead, but it's a bit of a mixed bag. Right now, the water is sitting at 68° which is a bit colder than we'd normally expect for this time of year, so you might want a slightly thicker wetsuit.

The first thing you'll notice is that we're in for a rough spell. For the rest of August and through the first few days of September, the wind is just howling out of the north and north-northwest, and it's coming from the wrong direction. It's going to be choppy and messy with a cross-onshore wind, and the quality will be poor. The swell energy is moderate, with readings around 300 to 500 (535 peak on Saturday the 29th August), but it's all blown out. We see an increase in swell size to around 6ft to 6ft on Monday and Tuesday, but the wind is too strong and onshore, making it a real struggle. Honestly, this setup looks more interesting for kite surfing than paddle surfing.

We then have a bit of a lull from Thursday the 3rd through to the 5th, with the swell dropping right down to 2ft or 2ft. The energy is weak (79 to 130). Not much to get excited about.

But then things start to look up. The first real glimmer of hope comes on Saturday, the 5th of September. The morning shapes up with a light offshore wind from the SE at just 3 mph, and the surf is small at 2ft from the NW. It's surfable, but very ordinary. The real standout is the following morning.

Sunday, the 6th of September is the one to circle. The morning is calling for glassy conditions with an easterly breeze at just 3 mph. The swell is reading 3ft from the NW, but look at that period – 12 seconds! That's a proper groundswell, and the energy is moderate (271). This is going to be clean, lined-up and fun. It's a small day, but perfect for a longboard or a fish. The only caveat is that this longer period swell can make beach breaks a bit unpredictable, but it should be just fine. After the wind picks up in the afternoon, it's over.

From there, the forecast becomes a bit of a mixed bag again. The following week has some pulses of 5ft swell, but the wind is unreliable. The water is a bit colder than normal, so keep that in mind. The long-range looks messy with more onshore wind, so don't hold your breath for the second week.

That's the picture from here. Keep your eyes on that Sunday morning glass-off.

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.
