Alright folks, Rusty here. Let’s break down the next couple of weeks. We’ve got a slow cooker of a forecast, so don’t expect any instant gratification.
The overall pattern is pretty flat to start, with a real dry spell. We’re looking at a long gap from today until the first real opportunity. Honestly, for the first several days, the surf is just a no-go.
The first proper window to wet a line opens up on Sunday morning, 12 July. That’s our standout for the entire period. Head to Castelejo. It’s a beach and reef setup, and it’s very consistent, so it’s always a reliable bet. The swell is a small 4 ft from the WNW, with a period of 9 seconds. The combined energy is moderate (211). The wind is glassy, coming from the SSE at just 3 mph. That’s a major positive—it’s going to be clean as a whistle. The water temp is 69°, which is about average for the time of year. This is the best on offer, and it’s a solid call for a Sunday morning session.
After that, we hit another rough patch. The wind is onshore or cross-onshore and lumpy through the week, with a few small waves around but nothing you’d want to paddle out for. The swell builds again towards the end of the following week, but it’s messy and windy.
Now, looking further ahead, there’s a promising but less certain window. On Tuesday afternoon, 21 July, the wind goes glassy again with a S wind at 3 mph. The swell is 5 ft from the NW with a 9-second period, and the combined energy is moderate (330). It’s worth penciling in, but it’s a long way out.
The swell bumps up a bit more around 20 July with heights around 6 ft to 7 ft from the NW, but the wind is cross-onshore or strong onshore, keeping it lumpy. The combined energy gets strong (794), but the wind kills it. For a beach and reef setup, that’s more of a kite-surfing scenario than a paddler’s dream.
So, to wrap it up: Sunday morning is your best bet. The rest is a waiting game, but the second week has a couple of possibilities if the forecasts hold.
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.
