The Lowdown
Alright, Rusty here, let's get into it. Looking at the 16-day window for our region, I gotta be straight with you: it’s a pretty grim run. We're looking at a whole lot of poor surf conditions with onshore and cross-onshore winds spoiling the fun for the vast majority of the forecast.
The only spot we've got to work with is Castelejo, a very consistent beach and reef setup. It's exposed to swell coming from the northwest, which is what the guidance says is ideal. But the wind... oh, the wind. It's just not playing ball.
The whole first week is a write-off. From Sunday the 26th of July right through to Saturday the 1st of August, the conditions are poor. Winds are coming from the north and north-northwest, smashing the coast with onshore to cross-onshore breezes. There's one brief glimmer: on the morning of Monday the 27th of July, we get a clean window with a light cross-offshore breeze from the east-northeast and a 4 ft swell (189 combined energy). It's a "surfable" window but very ordinary. That’s the only patch of clean surf in the entire first week. The rest of the time it’s choppy, lumpy, and messy.
After that, the second week doesn't let up either. From the 2nd of August all the way through to the 10th of August, it's the same story: persistent cross-onshore winds. The swell does build. For example, on Wednesday the 5th of August, we're looking at a 8 ft morning swell from the NW with a solid 751 combined energy, but with a fresh 19 mph cross-onshore wind, it will be lumpy and blown out. That kind of size with that wind might be more interesting for the kite crew than the paddle crowd. By Thursday the 6th, it's still big at 6 ft to 6 ft but messy.
To be honest, looking at the entire 16-day run, there’s no true standout session. The waves and the winds are just not lining up. That one window on the morning of the 27th is the best you’re gonna get, and even then it’s only a 4 ft swell. It’s a tough outlook.
Stay patient. The forecasts can change, but right now, it’s a hard pass for me.

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.
