The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the line for the Costa del Sol.
We’ve got a solid run of surf ahead, but it’s not a non-stop story. The first proper window kicks off early on Monday morning, the 7th of September. That’s where the real interest starts. After that, there’s a gap most afternoons where the wind goes onshore, killing the vibe, but the mornings are where it’s at.
The standout is hands down Monday morning, September 7th. We’re looking at a clean 4ft swell from the SSW with a 14-second period, giving it some proper push. The combined wave energy is solid (592), and with glassy conditions and a slight offshore breeze, it’s going to be smooth. Water temp is sitting at 87°, which is a touch warmer than normal for this time of year, so you can leave the thick suit at home. This is a beginner-friendly break, but it’s inconsistent, so patience will be rewarded. Expect some company as crowds are sometimes an issue, but for that quality, it’s worth it.
The mornings just keep giving. Tuesday the 8th drops to 2ft but with a long 18-second period, making it a proper groundswell. Again, glassy and clean. Wednesday the 9th is similar with 2ft and a 16-second period, offshore wind keeping it tidy. Thursday the 10th bumps back up to 3ft, 17-second period, and the energy jumps to 901 – that’s a noticeable spike. Glassy morning, looking excellent.
Friday the 11th is another cracker: 4ft, 16-second period, combined energy of 742, and dead calm winds. That’s as clean as it gets. The Saturday 12th and Sunday 13th mornings are smaller, 3ft and 2ft, but still glassy and fun for a longboard.
After that, the pattern holds. The mornings from Monday 14th through Tuesday 22nd offer consistent, clean surf, mainly in the 2ft to 4ft range, always with a nice long period and light offshore or glassy winds. The combined energy stays moderate to strong, often in the 400-900 range. The long-period swells (up to 21 seconds on the 18th) mean the waves will have real shape and power, especially for a point or reef setup, though at a beach break they can be a bit too straight.
The one true standout in the second week is Monday morning, September 21st. A 3ft SSW swell, 18-second period, and combined energy of 957 – the strongest reading of the whole run. Clear skies and a light cross-offshore wind will have it looking absolutely pristine. This one is a promise, but with the long-range, just keep an eye on it.
Headline: Monday morning, Sept 7th and Monday morning, Sept 21st are your best bets. Get on it.

Information about the Costa del Sol Surf forecast
The above surf forecast table for Costa del Sol provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Costa del Sol can be found by selecting the local surf guide option on the grey menu. Our Costa del Sol 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.

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 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.
