The Lowdown
Alright, Rusty here again. Let’s break down the Costa del Sol in feet and degrees.
We’ve got a decent stretch of surf coming, no dry spells to start with. The overall picture is consistent SSW groundswell with a good amount of push behind it. The water is sitting at about 87°F, which is a touch warmer than normal for this time of year, so the thick rubber stays home.
The standout session is Thursday September 10th in the morning. It’s the first one up and it’s the best early call. You’ve got clean 3ft surf from the SSW with a 17-second period (that’s real groundswell) and a light cross-offshore breeze from the NE. The combined energy is at 910 (moderate/strong). It’s going to be smooth, lined up, and fun. Just remember, it can get crowded here sometimes.
Friday morning September 11th is another cracker. Swell holds at 4ft from the SSW with a 16-second period, and the wind goes glassy from the ENE. Perfect conditions. Energy is still strong at 737. The size is friendly for all skill levels.
Into the second week, the quality dips a little but there are still great windows. Monday September 15th morning is a solid pick: 2ft SSW with an 18-second period and light cross-offshore wind. Energy 524 (moderate). Tuesday September 16th morning looks even better – 4ft SSW, 16-second period, offshore NE wind, energy 787. Thursday September 18th morning is a sneaky one: 2ft SSW with a very long 20-second period, glassy conditions, energy 530. Those long period swells can be a bit straight at beach breaks, but it still works here.
Saturday September 20th morning is a true standout in the later run. Clean 3ft SSW with a 19-second period, glassy east wind, and combined energy of 704. That’s quality surf, no doubt.
After that, mornings stay clean through the 25th, but the swell backs off a little.
If I’m picking the top two, it’s Thursday September 10th morning for the power and clean offshore breeze, and Saturday September 20th morning for the super long period glassy conditions. Get after it.
Rusty.

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.
