Alright, it’s Rusty here, giving you the lowdown for Castelejo in feet and miles per hour.
The next week and a half is mostly a bust. From Friday the 10th through the 19th, it’s ugly. Onshore and cross-onshore winds blow all day, and the swell is small and weak. The combined wave energy is low, mostly under 100, and even when it climbs a bit on a day like Sunday the 12th morning (209), the wind is still a problem. It’s all *poor surf conditions*.
The only real chance in that first week is Sunday morning, the 12th. Wind goes light offshore from the SSE, and the surf is a clean 3-4 ft from the WNW, with a 9-second period. Wave energy is moderate at 209. Water temp is about 69°F, which is normal for the season. That morning window is your one shot before the wind switches and messes things up by afternoon.
After that, it’s a long, drawn-out dry spell of onshore crud.
The big standout is Monday the 20th. Dawn patrol is the move – glassy conditions with a light NNE breeze at just 3 mph. Swell runs 4-5 ft from the NNW, period around 9 seconds, and the combined energy is a solid 333. The waves will be head-high plus, and with that glassy surface, they’ll be as clean as it gets in this forecast. That’s your session.
Further out, Saturday the 25th afternoon has a glassy window with a tiny N breeze. Swell is 5-6 ft from the NW, period 10 seconds, and the combined energy jumps to a strong 640. That’s serious power, and for Castelejo’s reef and beach setup, it could be excellent, but it’s also a bit too big for beginners. It’s 15 days out, so keep an eye on it, but don’t bet the farm.
Sum it up: Sunday the 12th morning works, but Monday the 20th is the one. Get on it.
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.
