The Lowdown

Alright folks, Rusty here. Let's have a look at what's cooking for our little corner of the coast.

We're looking at a bit of a mixed bag over the next two and a half weeks. There's a proper run of surf on the horizon, but you'll have to be patient through a pretty choppy and blown-out start. The real magic, if the forecast holds, looks to be centered around the 19th of September.

Right now, the water is sitting at 65°, which is a good five and a half degrees colder than normal for this time of year, so you'll want a thick wetsuit and maybe some boots.

Things kick off this Sunday the 13th of September afternoon. It's not huge, with a clean 4 ft NW groundswell and glassy conditions thanks to a light ENE breeze. The wave energy is moderate (406). It's small and clean, but honestly, the real quality is yet to come.

Monday the 14th stays clean in the morning with a similar 4 ft swell, but that's about the last of the good glass for a while. Tuesday and Wednesday see the swell bump up, but it comes with a lot of strong, onshore wind. Wednesday morning the 16th gets a bit hectic with a 8 ft NW swell and a 25 mph cross-on wind. The wave energy gets up there (771), but it's going to be a messy, choppy mess. Not one for the paddle board, might be more fun for the kite crew. That onshore wind sticks around through Thursday and Friday, with the swell staying over 7 ft and the conditions just too rough to get excited about.

Now, here's where it gets interesting. The 19th of September, Saturday, is the standout. The wind swings around to a light ESE cross-off, cleaning up a solid 7 ft NW groundswell. The period is a long 14 seconds, which means real groundswell energy. The combined energy hits a very strong 1728. This is proper, powerful surf. It's going to be a big day, and with that size and power, it's one for the experienced crew only. The wave quality is forecast to be excellent.

Saturday afternoon stays excellent too, with a 6 ft NW swell and the same clean cross-off wind. Sunday the 20th drops back a touch to a very clean 5 ft, which will be a lot more manageable. The swell direction from the NW is a perfect match for the break, and the cross-off winds are expected to continue into the start of the following week. Monday the 21st keeps the good form with a 4 ft to 5 ft long-period NW groundswell and light offshore E winds. Tuesday the 22nd is another treat, with a 5 ft NW swell and glassy conditions in the afternoon. This run from the 19th to the 22nd is where you want to be in the water.

After that, the surf tapers off. The 23rd and 24th see the swell drop and the winds turn onshore again. There's a glimmer of hope on the 26th of September with a clean 3 ft WNW swell and light offshore winds, but it's much smaller.

So, to wrap it up: don't bother with the mid-week mess. The window from Saturday the 19th through to Tuesday the 22nd is your best bet, with the 19th being the absolute standout for bigger, cleaner, powerful surf. Get on it.

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.
