The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for the next couple of weeks.
Honestly, it's a pretty grim outlook for the whole 16-day window. The water is a chilly 66° at Castelejo, which is 5° colder than usual for this time of year, so that’s a bit of a shock to the system. But the real problem is the wind. We’ve got a stubborn, persistent cross-onshore or onshore wind from the north, northwest, or north-northwest, blowing at 9 to 25 mph, and it's just tearing the place up. From Wednesday the 29th right through to Thursday the 13th of August, every single surf session is marked as "poor surf conditions." The waves are small, choppy, lumpy, and messy. There is no standout period, no hidden gem, nothing worth paddling out for.
The first week offers nothing. Wednesday the 29th has tiny 2 ft to 2 ft swell from the NW with a 9-second period, but the wind is already cross-on and the combined energy is a weak 131. It's a write-off. Thursday, Friday, and the weekend all follow the same pattern: small, wind-affected waves, with the combined energy often dropping below 100. On Friday the 31st, the swell period drops to a pathetic 5 seconds, making it just wind chop.
The second week is a bit more of the same, but with a little more size. From Monday the 5th of August, the swell height creeps up, reaching 5 ft on Sunday the 9th, and hitting 6 ft with a combined energy of 385 on the 9th afternoon. But the wind is still howling onshore or cross-onshore at 22 mph, so it's just going to be a messy, blown-out sea. The biggest swell of the run comes on Monday the 10th of August with a 6 ft NW swell and a very strong combined energy of 526, but even that is ruined by fresh to strong cross-onshore winds. Honestly, with that much wind, Castelejo is looking more like a kite surfer's playground than a surfer's wave.
There are no good surf options in this 16-day window. It’s a long, blank run. The setup is just a straight beach and reef, exposed to the wind, and the wind is not playing ball. Sometimes it's just like this, a persistent wind pattern that kills the quality. Fingers crossed the forecasts change, but for now, I'd leave the board in the car.
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.
