The Lowdown
Alright folks, Rusty here. Let's be straight with you. Looking at the charts for Castelejo over the next 16 days, I gotta say, it’s a pretty grim picture for us surfers. There are no good surf options in this whole 16-day window.
Right from Sunday the 26th, we’re waking up to a real mess. The water’s a bit colder than usual for this time of year, sitting at 66°F. But the real heartbreak is the wind. Sunday afternoon kicks off with a fresh 22 mph NNW cross-onshore. We get a 5ft NNW windswell, but with a period of only 7 seconds, the combined energy is weak (239), and the wind has got it all chopped up.
We move through the week, and it just doesn’t get any better. Monday the 27th through to Saturday the 9th of August is just a long, drawn-out run of poor conditions. Swell heights bob around 3ft to 4ft, but the period stays mostly short, between 5 and 10 seconds. The real killer is that persistent NNW wind. It's almost always a cross-onshore or onshore breeze, anywhere from 9 to 25 mph. This keeps the surface lumpy, choppy, and messy for paddle surfing.
The setups all look more interesting for kite surfing than paddle surfing, honestly. There’s one brief moment on Thursday morning the 30th where the combined energy drops to just 97, but the wind is still up, so it’s a washout. On the 9th of August, the afternoon shows a bit more energy (315) with a longer 10-second period from the WNW, but the 19 mph onshore wind just ruins it.
Even into the second week, from the 10th, there's no light at the end of the tunnel. We get some moderate energy (273 and 237) on the 10th, but it's with a cross-onshore to onshore wind again. It is what it is. A blank run like this is pretty normal for the area when the wind sets in from the north. Forecasts can change, so don't toss the board in the shed just yet, but for now, I’d save the gas money.
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.
