The Lowdown
Alright, let’s get into it. The Costa del Sol has a bit of a slow start, but once we get past the first few days, there’s some real quality lining up. We’re looking at a run of clean, glassy mornings with a steady SSW groundswell, and the water temp is sitting about average for this time of year, nothing wild.
Thursday morning (20th August) kicks things off with a small but clean 3ft SSW swell at 14 seconds, and the wind is glassy from the NE. It’s a slow-burner, but the wave energy is moderate (354), and the sets will have a nice shape for a beginner-friendly wave. The break can be inconsistent, but when it’s on, it’s a fun little wave. Crowds are sometimes an issue here.
Friday morning (21st August) is the first real standout. We’ve got 4ft of S swell, 12 seconds, and glassy E wind. The energy jumps to moderate (632), and those waves will have better push. This is the best morning of the first week – clean, fun, and plenty of shape.
Saturday and Sunday mornings (22nd and 23rd August) stay clean with light cross-off winds, but the swell drops back to 3ft and 2ft. Still good for a session, but not the peak.
Now, let’s talk about the end of the month. 28th August (Friday morning) shows a 2ft SW swell with a very long 19-second period, and clean cross-off wind. The energy is strong (814), and that deep-water groundswell will wrap in nicely. The break is exposed to SSW, so this long-period SW swell will really line up. Sets will be well-spaced, making it easier to pick them off.
But the real star is Saturday, 29th August. Morning delivers 5ft of SSW swell, 16 seconds, with clean offshore NNE wind. The energy is very strong (1258). This is expert territory – too big for beginners, but for anyone with experience, it’s going to be firing. The afternoon goes glassy with no wind, same size, and it’ll be a classic long, clean session. This is the best on offer without a doubt.
Sunday, 30th August, is still excellent – 5ft SSW, 15 seconds, clean offshore again, strong energy (876). The quality holds right into Monday morning (31st August) with 3ft SSW and clean conditions.
After that, the first week of September keeps a similar pattern: 3ft to 3ft SSW swells, clean mornings, and the odd good afternoon. Friday, 4th September, has a 4ft SSW swell with a 16-second period and cross-off wind, energy at 799 – a promising end to the outlook, though it's a fair way out.
All in all, if you’re picking your moment, the morning of the 29th August is the one to circle. That’s the big, clean, powerful session. The mornings are the winner here – afternoons get trashed by onshore wind and chop. Keep it dawn patrol.

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. If you surf the same spot (Costa del Sol) 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 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.
