The Lowdown
Alright gang, Rusty here. Let’s break down the next couple of weeks for the Costa del Sol.
Right from the start, we’ve got swell coming in steady, but you’ve gotta be an early bird. The mornings are consistently clean with light or offshore winds, sometimes flat calm. The afternoons? They get blown out by onshore breezes, so don’t bother. Early sessions only.
We kick off Sunday, August 23rd, with a clean 2ft SW swell running at 14 seconds. That’s proper groundswell energy (430) and a light ENE cross-off breeze. Water temp is around normal for the season, nothing out of the ordinary.
Monday the 24th is much the same: 2ft SSW, 18-second period, clean cross-off winds. Energy up a bit to 475. Fun little rollers.
Tuesday the 25th: 2ft SSW, 16-second period, light NE winds. Clean and consistent.
Wednesday the 26th: a touch smaller at 2ft, but we get true offshore NE wind. Period is 15 seconds, energy 224. Clean little waist-high runners.
Thursday the 27th: smallest day at 1ft, 18-second period, still clean with cross-off winds.
Now, Friday the 28th morning is where things perk up. We get 3ft SSW swell, 16-second period, and dead glassy conditions. Energy jumps to 640. That’s a standout morning for clean, fun waves.
Saturday the 29th morning gets better. Swell bumps to 4ft from the SSW, 16 seconds, and the energy hits four digits (1012). Flat calm, glassy. This is excellent for experienced surfers, still manageable for strong intermediates.
Sunday the 30th morning: 5ft, offshore NE wind, energy 840. Clean and solid.
Monday the 31st and Tuesday September 1st: the swell drops to 4ft and 3ft, both mornings glassy. Easy clean waves.
Wednesday the 2nd of September morning: only 2ft but with a 17-second period and glassy conditions (411 energy). The long period will wrap nicely for clean peelers.
Thursday the 3rd of September morning: 2ft, 16 seconds, glassy. Fun.
Here comes the big one: Friday the 4th of September morning. We’ve got 5ft SSW groundswell with an 18-second period and combined energy of 1568. North wind, glassy conditions. This is a powerful clean swell—experts only territory. This is the one to plan for.
Saturday the 5th of September morning steps it up again: 6ft SSW, 16 seconds, offshore NNE wind, energy 1713. Again, big and clean. These two days are the clear standouts of the whole window.
Sunday the 6th and Monday the 7th of September mornings offer a clean drop back to 4ft and 3ft, with offshore and glassy winds. A nice mellow finish.
So the story is clear: mornings are golden, afternoons are a wash. Friday the 28th is a glassy gem, but the real heavy hitters are Friday the 4th and Saturday the 5th of September. Set that alarm.
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.
