The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer for Castelejo over the next couple of weeks.

First thing you need to know: this is a tough stretch. For a spot that’s normally a reliable little machine, the next 16 days are looking pretty average to downright ugly. There’s no surf on offer at all right now, and we’ve got a long gap of poor conditions stretching from the 25th of August all the way through to the 2nd of September. That’s a serious dry spell. The water is much colder than normal for this time of year (66°F), nearly 5°F below the seasonal average, which is notable.

Things do start to look slightly more interesting from the 3rd of September, but it’s not going to set the world on fire. The real standout for the whole period is going to be the morning of Friday the 4th of September. That’s the one to put a circle around.

The Pick: Friday 4th September (Morning) – Castelejo

This is the only window that really gets me talking. We’ve got a clean 5 ft swell from the NW, and the wind is light and offshore from the SE, swinging to just 3 mph. That’s glassy, clean conditions for a beach and reef setup. The combined energy is moderate (282), and the period is a short 8 seconds, so it won’t have huge power, but that offshore breeze will be the star of the show. The crowds can be an issue here, so expect company, but for this spot, with that wind, it’s the best you’re going to get. This is beginner-friendly height, so a good one for a range of surfers.

The rest of the run-down:

Before that standalone morning, everything is compromised. The 3rd of September (Thursday) has a clean morning with light cross-offshore winds and a 3 ft swell, but it’s a poor rating – “surfable but very ordinary.” It’s there if you’re desperate.

After the 4th, things get messy again. The Saturday afternoon of the 5th of September sees a jump in size to 6 ft from the NW with a very long period of 12 seconds (combined energy 980 – strong), but an onshore wind of 16 mph spoils it. That kind of period and energy wants a sheltered reef or point, but the wind will make it a washing machine at a beach and reef setup. That’s more of a kite-surfing session than a paddle session.

A quick heads up for Wednesday the 9th of September – the swell bumps up to 7 ft to 8 ft from the NNW, with moderate energy (560-663). That’s edging into expert territory size-wise (over 8 ft on the afternoon), but the wind is cross-onshore at 9 mph. You’ll have size but no quality. Not one to get excited about.

So keep your powder dry, wait for that Friday morning (4th Sept), and get the offshore lines while they last. It’s not a classic run, but there’s a window in there.

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.
