The Lowdown
Alright folks, Rusty here with a look at the Costa del Sol for the next couple of weeks.
We’ve got a slow start, but the first real chance at some waves is Friday morning, September 4th. The ocean is alive with a solid 4ft swell from the SSW, with a long 17-second period. That’s proper groundswell, and it’s got a combined energy of 1137 (moderate wave energy). The water is sitting at 88°, which is a touch warmer than usual for this time of year. The wind is glassy, coming light from the SE at 3 mph. It’s excellent for experienced surfers, but that 4ft on a long-period swell will be a bit much for beginners. The break is inconsistent, so don’t expect non-stop waves, but when they come, they’ll be clean.
Friday afternoon, the wind swings onshore from the SW at 9 mph, and the surf gets a bit messy. The swell bumps up to 5ft, but the onshore wind ruins the quality. It’s a marginal call.
Saturday morning, September 5th, is a standout. The wind is dead calm, glassy as can be. The swell holds at 5ft from the SSW with a 16-second period, energy at 1304 (moderate wave energy). Conditions are excellent for experienced surfers. The water is still warm. The crowds are possible here, so get out early.
Sunday morning shows a drop in energy to 833 (moderate wave energy) with a 5ft SSW swell. The wind is a light cross-shore from the ESE at 3 mph, which keeps things ridable but not perfect.
Monday morning, September 7th, has a glassy start with no wind, but the swell is down to 4ft from the SW with a 14-second period. Energy drops to 579 (weak wave energy). It’s good, clean fun, but not the big stuff.
After a few days of small, clean surf in the mornings and onshore afternoon slop, the next real highlight comes on Thursday morning, September 10th. The wind is offshore from the NE at 6 mph, the swell is 3ft from the SSW with a 17-second period, and the energy is 859 (moderate wave energy). It’s clean, lined up, and worth a paddle.
We see a similar pattern through the following week: clean mornings, blown-out afternoons. The swell stays small to moderate, with the best wind windows on the 15th (Tuesday morning) and the 16th (Wednesday morning). On the 16th, we get a 4ft SW swell with a 16-second period and glassy conditions from the NNE at 3 mph. Energy is 657 (weak wave energy). It’s a nice, clean session.
The long-range outlook is promising but less certain. The 18th of September, Friday morning, shows a juicy 3ft SSW swell with a very long 21-second period, and clean cross-offshore wind from the E at 6 mph. Energy is 954 (moderate wave energy). That’s a proper groundswell, and it’ll be beautiful at the right tide, but it’s a long way out.
Right now, the pick of the entire forecast is Saturday morning, September 5th. Get it while it’s glassy.
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.
