The Lowdown
Alright folks, it’s Rusty here. Let’s have a look at what’s coming up for Castelejo.
To be straight with you, the first week is a real grind. Wind and swell just aren't lining up. From Friday the 24th right through to Wednesday the 30th, it’s mostly onshore and cross-onshore breezes mucking up the surf. The swell is small and weak, with energy readings mostly under 250 (moderate at best) and a lot of it under 100 (weak). The water is sitting at 67°F, which is a bit colder than average for this time of year, so you’ll want a decent wetsuit.
We get a little window on Thursday morning the 30th – glassy conditions with a tiny 1ft swell from the WNW, period around 10 seconds, but energy is just 71 (weak). It’s surfable but very ordinary. Friday the 31st morning is glassy again with a tiny 1.0ft, and then Friday afternoon the wind goes light cross-off and the swell bumps to 3ft with a longer 11-second period and energy of 195 (moderate). It’s clean, but still pretty small. Not worth getting too excited about.
Now, the standout is Saturday the 1st of August. That morning, we’ve got a clean 7ft groundswell from the WNW, period a solid 13 seconds, and the energy is pumping at 1704 (strong). Wind is light offshore from the ESE. This is the real deal for experienced surfers – powerful, clean, and well-shaped. The afternoon does get a bit onshore from the NW, so the morning is your window. The swell is a touch over 6ft, so it’s expert territory. Crowds are possible here, so be ready for company.
Sunday the 2nd still has good size – 7ft in the morning from the NW with a 12-second period – but the wind is cross-onshore from the N at 12 mph, making it choppy and not as good as Saturday. The energy is still strong at 1233, but the wind is a letdown. After that, the following week goes back to onshore winds and smaller, messy surf, with energy readings dropping into the 200-400 range. Nothing to clear your schedule for.
So, to sum it up: the first week is a write-off for most of us. The absolute best on offer is the morning of Saturday the 1st of August at Castelejo – that’s your one to chase. It’s a long-range call, so keep an eye on it, but it's looking promising.
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.
