The Lowdown

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

We're looking at a pretty bleak stretch for the most part. The swell is struggling to get its act together, and when it does show up, the wind is just wrecking it. The first few days are a write-off, with poor surf conditions and cross-onshore winds making a mess of things. The water temperature is about average for this time of year, so nothing to note there.

Honestly, the only real window of opportunity comes on Saturday the 12th of September. It's not going to be a world-beater, but it's the best we've got. The morning sees a light offshore wind from the SE, which will clean things right up. The swell is tiny, only 3ft from the NNW, and the combined energy is weak (67). The period is a short 7 seconds, so it'll be a bit bumpy and weak, but clean. The afternoon loses the wind, going cross-shore, so the morning is the only call.

There is another small window on the morning of Sunday the 13th of September. A tiny 1ft NW swell with a longer 13-second period, and the wind is glassy. The combined energy is still weak (166), but it will be clean. It's a very small wave, but for a longboard or a foamie, it might be your only glassy option.

After that, things get messy again. We get a bit more size, but the wind picks up again, and by the final week, it's mostly cross-onshore junk. The morning of Saturday the 19th of September shows a 5ft WNW swell, but the wind is cross-on, leaving it as a marginal option at best.

To sum it up, don't get your hopes up for this run. The waves are small and the wind is mostly bad. The standout is the morning of Saturday the 12th of September. It's tiny, but with that offshore wind, it'll be the cleanest wave you'll see this fortnight. The glassy morning of the 13th is also a very, very small consolation.

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.
