The Lowdown

Alright, Rusty here again, giving you the same story in feet and miles.

Honestly, I’ve gotta say it straight – this 16-day window is a tough one for Castelejo. The surf's on the small side and the wind is just not playing ball. We’re talking about a stretch that starts Friday the 31st of July and runs through to Saturday the 15th of August, and every single session is flagged as poor conditions. There is no standout, no hidden gem in this run. The wind is mostly a cross-onshore or onshore affair, with a fresh breeze, and that’s keeping the ocean lumpy and choppy. The swell is tiny, mostly under 3 ft, and the period is short, so there’s no real push.

The first week, from the 31st right through to the 6th of August, is a write-off. We’re looking at weak wave energy, values like 54 and 62, with a brief bump to 147 on the 1st, but it’s still a poor 2 ft from the west. The water is feeling much colder than normal for this time of year, sitting at 66°F with a -4°F anomaly, so you’ll want a thick wetsuit if you’re mad enough to go for a paddle.

There’s a slight pulse in the second week, around the 8th and 9th of August, where the combined energy climbs to 221 and 190, with swell heights reaching 4 ft to 5 ft. But the wind is still cross-onshore from the NNW at 19 to 22 mph, and the period is short at 6 seconds, so it’s just messy, lumpy, and not worth the fight. The swell direction is NW, which is a good match for the break’s optimum, but the wind ruins it.

From the 11th to the 15th, the energy stays moderate to strong (234 to 297), but again, the wind is relentless. The 13th of August shows a 5 ft swell from the NW with 297 energy, but with a strong breeze onshore, you’d be better off watching from the cliffs.

Bottom line: don’t bother. This is a solid 16-day gap with no decent surf. The breaks are very consistent here, so it’s unusual to have such a blank run, but forecasts can change. For now, leave the board at home.

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.
