The Lowdown

Alright, let’s break it down. Rusty here, and for Castelejo, the first half of the forecast is brutal.

Starting Thursday the 27th of August through Wednesday the 2nd of September, it’s all poor. Swell runs from 0.9ft to 7ft, but the wind is cross-on or onshore from the N or NNW, blowing 15 to 25 mph. That means lumpy, choppy, messy conditions – not worth suiting up. Wave energy is moderate to moderately strong (346 to 1127), but with that wind, it’s a mess. For beginners, anything over 5ft gets too big, and at 7ft it’s expert-only anyway. Kite surfers might find it more interesting than paddle surfers.

Thursday the 3rd of September is marginal – morning has a light cross-on breeze and 5ft swell (244 energy), just okay.

Then we get a real highlight: Friday the 4th of September, early morning. It’s glassy – dead calm with a light NE breeze at 3 mph. Swell is small, 3ft from the NNW with an 8-second period (138 energy). Not big, but clean and fun. Water temp is around 68°F (a bit colder than normal, about 3°F colder), so grab a wetsuit. Crowds show up “sometimes,” so you might have a few out, but for glass like this, it’s worth it.

Saturday the 5th and Sunday the 6th of September are back to poor – cross-on, fresh breeze, small swell.

Monday the 7th of September morning is the next standout. Offshore wind from the SSE at 6 mph, clean conditions, and 3ft swell from the NW with a 10-second period (308 energy). Solid clean session for the early birds. Afternoon gets a light cross-on, but morning is the call.

Tuesday the 8th of September is small but clean – 2ft, offshore ESE wind, 10-second period (114 energy). Nothing special, but you can get a few.

Wednesday the 9th of September is the best of the stretch: morning has offshore wind from the ESE, 2ft swell with a very long 13-second period from the WNW (234 energy). Long-period groundswell like that will make small waves peel nicely on this beach-and-reef setup. Clean. Afternoon is also clean with 3ft at 12 seconds (307 energy) and a cross-off breeze. Two clean sessions back to back.

Thursday the 10th of September morning has moderate offshore wind (ESE 15 mph), clean, with 3ft from the WNW at 11 seconds (262 energy). Afternoon goes glassy (0 mph) with 3ft. Small, clean windows.

Friday the 11th of September finishes with a glassy afternoon – 2ft, 9-second period, no wind. Rideable but ordinary.

The true standouts: glassy Friday morning the 4th of September for the cleanest small waves, and Wednesday the 9th of September – both morning and afternoon – for that long-period groundswell and clean wind. That’s the best on offer after a rough 6-day start. The second week brings smaller but cleaner windows. Keep an eye on it – near-term calls are solid, later ones a bit less certain.

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.
