Table - best surf conditions forecast for Castelejo over the next 16 days.
Hey, it’s Rusty again, looking at Castelejo for the next couple weeks. I’ll be honest, it ain’t pretty. This beach and reef spot is usually consistent, but for the next 16 days, the conditions are just poor. You’re looking at nothing but onshore and cross-onshore wind, and the surf quality is shot across the board. There’s no standout session, and nothing I’d recommend you paddle out for.
From Monday, July 13th through to Sunday, July 26th, it’s a long, messy run. Swell heights range from 1 ft to a bit over 4 ft, but it’s constantly blown out. The wind is from the NW to NNW, either onshore or side-onshore, with speeds ranging from 9 mph up to a stiff 22 mph. The swell periods are short, mostly 5 to 9 seconds – pure windswell. The combined energy readings are weak to moderate, mostly under 100, with a couple days like the 24th and 25th nudging into the low hundreds, but the wind wrecks any shape.
On Monday, July 27th and Tuesday, July 28th, the swell finally kicks up – we’re talking 7 ft to 8 ft from the NW, with an 8-second period. That’s a lot of energy (671 and 771). But the wind is still cross-onshore at 19 mph, making for lumpy, fast-moving walls. At over 8 ft, that’s expert-only territory, and with the wind blowing across it, it’s gonna be messy. Honestly, that looks more like a kitesurfing day than a surf day.
Water temp is about normal for the season. Nothing wild there.
So, bottom line: there’s no good surf in this 16-day stretch. The wind doesn’t let up, and when the swell does come, it’s blown out. Sometimes you get a run like this. Forecasts can change, but right now, just leave the boards 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.
