The Lowdown
Alright folks, Rusty here. Let’s have a look at what the Costa del Sol has lined up for us over the next couple of weeks.
The overall pattern is a persistent, long-period SSW groundswell running for days, but the window for clean waves is almost exclusively in the mornings. The afternoons get blown out by a solid onshore seabreeze, so you gotta be an early bird. The water is sitting at 87°, which is a touch warmer than normal for this time of year, so you can leave the thick rubber at home.
We start off Monday the 17th with some real promise. Costa del Sol is seeing a 3ft SSW groundswell with a long 14-second period. The morning is glassy with a light northerly breeze, making for clean, workable conditions. The combined energy is moderate at (442). It’s a good, easy start to the week.
Tuesday the 18th and Wednesday the 19th follow the same script: glassy or light offshore winds in the morning with that same consistent 3ft SSW swell. Wednesday’s swell stretches out to a 15-second period, adding a bit more punch. The mornings are the only show in town, though.
Thursday the 20th and Friday the 21st keep the rhythm going. Thursday morning is glassy with a slightly smaller 2ft SW swell, and Friday morning is dead calm with a 3ft SSW swell. Both are clean, but the swell energy dips a little on Thursday to (309).
Saturday the 22nd is a bit of a write-off with a morning cross-shore breeze making things bumpy, and the afternoons are consistently poor. Sunday the 23rd bounces back with a glassy 2ft SSW swell in the morning. The following week, from Monday the 24th through Thursday the 27th, the swell slowly drops off, bottoming out at 1ft on the 27th. The mornings stay clean, but the size gets pretty marginal for a proper session.
Now, here’s where it gets interesting. Friday the 28th morning sees a bit of a pickup with a 3ft SSW swell and a clean cross-offshore breeze.
The real standout is Saturday the 29th of August. That morning, the Costa del Sol gets a 3ft SSW groundswell with a very long 17-second period. The wind is a light cross-offshore, and the combined energy jumps to a strong (814). This is a proper groundswell with real grunt. Because the period is so long, it’ll be better shaped at the points and reefs, but the swell is still a manageable size for most. The forecast says "very good surf conditions," and I’d have to agree.
But the absolute pick of the entire run is Sunday the 30th of August. The swell pushes up to 5ft from the SSW with a 16-second period, and the combined energy is a powerful (1164). With a light cross-offshore breeze in the morning, the conditions are described as excellent for experienced surfers. At 5ft, it’s getting a bit solid for beginners, but for anyone with a bit of experience, this is the morning to clear the schedule. This is a serious, high-energy swell with clean conditions.
The run continues into Monday the 31st with a 5ft SSW swell and clean morning conditions, before easing off into the start of September. The afternoons remain blown out throughout the entire forecast period, so don’t bother sleeping in.
Rusty.

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 Costa del Sol 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.
