The Lowdown
Alright, Rusty here again. Let’s break it down for the imperial folks.
It’s a rough run for Castelejo. The water is 66°F, which is 4°F colder than normal for the season – that’s a real chill, so pack a thicker suit.
The first week and a half is a total dud. From Sunday August 2nd through Sunday August 16th, the surf is poor. Onshore and cross-onshore winds from the NNW, often a fresh breeze at 15–22 mph, just messing up the surface. Swell heights are 2–5 ft, but it’s short-period windswell (6–9 seconds), with wave energy mostly weak to moderate (between 52 and 454). The wave comment is "poor surf conditions" the whole time – lumpy, choppy, not worth the effort.
There’s a gap of nearly two weeks with no real recommendation. The only hope comes on Monday August 17th. The morning shows a 8 ft NW swell, 8-second period, combined energy of 654 (strong). The wind is light from the NW at 9 mph and "on" – so it’s clean. The afternoon pushes to 8 ft from the NNW, with a massive combined energy of 1055 (very strong), but the wind picks up to a moderate breeze. The morning window is the standout: that 8 ft NW swell with light wind is the only real opportunity in the 16 days.
This break is a beach-and-reef setup, very consistent, exposed to NW swell. It’s a beginner-friendly spot, but that 8 ft swell is pushing it for beginners. For the experienced crew, Monday morning August 17th is the one to watch – but it’s a long way out, so stay tuned.
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.
