Updates in  hr  min  s Forecast update imminent

Alright folks, Rusty here. Let me take you through what’s cookin’ for Castelejo over the next couple of weeks. I gotta be straight with ya—this is a tough stretch. The forecast is lean for a long while, so we’re looking at a big gap before anything remotely worth paddling out for shows up.

We kick things off on Saturday afternoon, July 4th. Castelejo is a beach and reef setup that’s very consistent, exposed to the NW. The water’s sittin’ at 67°F, which is about normal for this time of year. That first session gives us a tiny 2ft swell from the NNW, period of 9 seconds, but the wind is glassy—dead calm. The combined energy is weak at 137. It’s surfable, but honestly, it’s just very ordinary. Not somethin’ to get excited about.

Then we hit a real dry spell. From Sunday, July 5th, right through to Friday, July 10th, it’s all poor surf conditions. Wind’s either cross-on or onshore, swell is tiny, and the period is short and weak. There’s nothing here for a surfer. This gap runs for the better part of a week with no solid recommendation.

Things start to perk up a bit on Friday, July 10th, but don’t get your hopes up. We see a bit more size—4ft from the NW—and the combined energy climbs to 127 (moderate), but the period is a weak 6 seconds and the wind is onshore at 12–15 mph. It’s still rated as poor conditions. The same story carries through Saturday the 11th and Sunday the 12th, though Sunday afternoon bumps the energy up to 253 with a 4ft NW swell at 9 seconds. But again, that onshore wind spoils it.

Now, here’s the one that might get your attention if you’re patient. Over a week away, on Saturday, July 18th, the afternoon session looks like a stand-out. We’ve got a clean 3ft swell from the NW, 8-second period, combined energy of 167, and the wind is a light cross-onshore with just small ripples. It’s not perfect, but after all this chop and junk, that glassy-ish window is the best we’ve seen. Castelejo should have some fun little waves. The consistency holds, so there’s plenty of chances to snag a set.

The final days, Sunday, July 19th, bring the biggest swell of the whole forecast—5ft to 6ft from the NW, with energy jumping to 300 and 379. But the wind is crankin’ at 18–25 mph from the NNW, strong cross-onshore and messy. That size with that wind? This beach and reef setup is gonna look more like a kite-surfing zone than a paddle-surfing spot. Not one for us.

So, bottom line: there’s a long, barren gap early on. If you’ve got the patience, the afternoon of Saturday, July 18th is your best shot—small but clean. Everything else is wind-affected or just too weak. Hang tight, and keep an eye on the charts.

Stay stoked,
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.
