The Lowdown

Right, mate, Rusty here. Let’s have a look at what’s cookin’ for the next sixteen days at Castelejo.

First off, I gotta be straight with you – the water’s proper chilly for this time of year, sittin’ at 66°F with a temperature anomaly that’s 4°F colder than usual. That’s a solid few degrees off the norm, so you’ll want a decent steamer.

Now, for the surf itself… it’s a tough one. The whole sixteen-day window is a bit of a write-off. There’s not a single morning or afternoon that’s worth paddling out for. The first few days, from the 3rd to the 5th of August, we’ve got tiny little 2ft to 3ft swells coming from the west or west-northwest, with a short period of 8 to 9 seconds. The wind is mostly onshore or cross-onshore, with moderate to fresh breezes, and the wave energy is weak, sitting between 50 and 141 (moderate to weak). The reports are all flagged as “poor surf conditions” with a score of zero. It’s just not happening.

That wave energy picks up a bit from the 6th to the 8th, with heights reaching 5ft to 6ft and combined energy jumping into the 200s (moderate energy), but the period drops to a messy 6 to 7 seconds, and the wind is a fresh 19 to 22 mph from the north or north-northwest, making it lumpy and cross-onshore. The water is still cold, and the reports are still saying “poor surf conditions.” It’s just a choppy, blown-out mess. Not worth a second look.

We go through a quiet spell from the 9th to the 15th, with swell heights dropping back to 1ft to 3ft, and the energy falling back under 100 (weak) for most of it. The wind is still a problem – moderate to fresh cross-onshore breezes keep things messy. The 11th and 12th show a bit more energy (194 and 215) but it’s still paired with poor conditions and onshore wind.

The last couple of days, the 16th, 17th, and 18th, see a bit of a pulse. Swell heights climb to 6ft, then 6ft, and up to 7ft on the 17th, with the energy getting strong (401 to 491). But the period is still short (6 to 8 seconds), and the wind is a fresh 19 to 22 mph from the north-northwest, either onshore or cross-onshore. Wave comment: “poor surf conditions.” It’s big, but it’s ugly.

Honestly, there’s not a single standout in this whole run. The swell direction is mostly from the NNW or NW, which is not the optimum direction for Castelejo, as it prefers a more northwesterly swell. The wind is always blowing from the wrong side, keeping it choppy and messy. For a beach-and-reef break like Castelejo, I’d say this setup looks more interesting for a kite surfer than a paddle surfer, given the consistent onshore wind and manageable swell sizes. There’s a real gap of about 16 days here with no decent surf on offer. The forecast can change, but right now, it’s a flat, blown-out stretch.

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.
