The Lowdown

Alright folks, Rusty here. Let's have a look at what's shaking for Castelejo over the next couple of weeks.

First thing you need to know – the water temperature at Castelejo is sitting at 67°F, which is a solid 4°F colder than usual for this time of year. That’s pretty noticeable, so don’t be a hero; bring the thick rubber or even a hood if you’ve got one.

Honestly, for the majority of this 16-day window, we are looking at a tough stretch. The surf is on offer but the conditions are getting in the way most days. The first few days are tiny and mostly blown out, so don't get your hopes up for Wednesday the 19th or Thursday the 20th. There's a bit of weak swell around, but the wind is just messy.

We do have a couple of moments where it might be worth a paddle. Let's look at Sunday the 23rd. We’ve got a glassy morning with no wind at all, and a little 3ft swell from the NNW with an 8-second period. The combined energy is weak at 141, so it won't be pumping, but with the wind completely calm, the surface will be like a mirror. It’s a "surfable" option, but very ordinary. The afternoon stays clean with a light cross-off breeze. It’s not a standout by any stretch, but if you just need to get wet, that’s your window.

Now, if you are an experienced surfer and willing to battle the wind, the end of the month and start of September sees a jump in size. On Monday the 31st of August, we see the swell building to 5ft in the morning and 6ft in the afternoon from the NW, with a period around 9 seconds. The combined energy jumps significantly to 387 in the morning and a strong 805 in the afternoon. The problem is, it’s accompanied by an onshore wind. Tuesday the 1st of September morning has 5ft swell from the NW (10-second period) and 522 combined energy, but again hammered by a strong cross-onshore wind.

Because the predominant breaks here are a beach-and-reef setup, and we are getting consistent onshore and cross-onshore winds with decent size, the setup honestly looks more interesting for the kite surfers than for a paddle surfer on most of these bigger days. There’s energy there, but the wind is just ruining the face for a traditional surfer.

The best call? If you are desperate, the glassy window on Sunday the 23rd of August is the only time it looks clean, even if the waves are small and weak. That’s your one true standout, but it’s a tame one. For the bigger stuff, you’d be battling the wind every time.

Rusty, signing off.

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.
