The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this 16-day window for Castelejo is a tough one. We’ve got a whole lot of poor surf conditions and not much to get excited about for the next week. It’s a real quiet spell, but there are a couple of days where things might just come together for a paddle.
Right now, from Thursday the 23rd through Sunday the 26th, it’s a write-off. Blustery NNW winds are hammering the coast, mostly onshore or cross-onshore, and the swell is small and weak. On Saturday morning the swell pushes to 4ft with a short 7-second period, but with 15 mph winds on it, it’s just messy. Saturday afternoon sees the swell hit 5ft and the combined energy climbs to 205 (moderate), but it’s still a lumpy, blown-out mess. The water temperature is 67°, which is a bit colder than normal for this time of year.
The first real glimmer of hope comes on Monday the 27th. The swell is still small, around 4ft from the NNW, but the wind finally swings offshore. We’re looking at a light ENE breeze at 3 mph in the morning, cleaning things right up. The combined energy is 173 (moderate), and the wave comment says "surfable but very ordinary." It’s not going to be pumping, but for a quick session on a clean, small board, it’s the best we’ve seen. The afternoon stays clean with a light SSW cross-off wind.
Then we hit another dry patch. Tuesday the 28th through Saturday the 1st of August is a grim stretch of small, weak swell and cross-onshore winds. The waves get tiny, dropping to 1ft on the 2nd of August, with that combined energy reading just 74 (weak). It’s not looking good for a paddle.
Monday the 3rd of August is our next standout. The swell is still tiny at 2ft from the WNW, but the wind is offshore again. A light ENE breeze in the morning and a clean ESE offshore in the afternoon will make those small waves glassy. The combined energy is only 92 (weak), so it’s a longboard or a foiler’s special. The period is 8 seconds, so it’s not packing much punch.
Tuesday the 4th of August is the best of the lot. We’ve got a 2ft swell from the WNW, but the period jumps to 11 seconds – that’s a proper groundswell. The wind is offshore most of the day, with a 15 mph SE breeze in the morning. The combined energy is 106 (moderate), and the wave comment is "surfable but very ordinary." This is the one to watch. That longer period will give the waves some shape, and with clean offshore winds, it’s your best chance for a decent wave. The break is a beach and reef setup, so that longer period might make it a bit more walled up, but it’s still worth a look.
The rest of the forecast after that softens back into small, onshore junk. There’s no big swell on the horizon, and the consistent winds are from the wrong direction. It’s a period where the setup looks more interesting for a kite session than a surf one, if you’re into that.
Keep an eye on Monday the 3rd and Tuesday the 4th of August. That Tuesday is the standout, but it’s a long way out, so don’t lock it in just yet. For now, the ocean is in a lazy mood.
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.
