The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the Costa Sol stretch over the next couple of weeks.
First up, the water is sitting at 88°, which is a touch warmer than normal for this time of year. That’s a nice little bonus if you’re paddling out without a suit.
The first bit of surf worth getting excited about kicks off on Friday morning, the 31st of July. We’ve got a 4ft SSW swell rolling in with a 13-second period. The combined energy is moderate at 566. The wind is light and cross-shore, so it’s not going to be perfect, but it’s rideable. The afternoon turns choppy, so get out early.
Saturday the 1st of August drops a little to 3ft from the SSW, but the morning cleans right up with a light cross-offshore breeze. That’s a decent window for a paddle. The afternoons are a write-off with onshore wind.
Now, Sunday the 2nd of August is a real treat for the early birds. Glassy conditions, zero wind, and a small 2ft SSW swell. It’s tiny, but clean as a whistle. Perfect for a longboard or a funboard if you just want to glide.
Monday the 3rd and Tuesday the 4th of August keep the small stuff rolling with 3ft and 2ft respectively, both with clean morning windows. The swell energy is moderate, sitting around 333 and 212. Not setting the world on fire, but you’ll get a few.
Wednesday the 5th of August is a glassy morning again with 2ft, but the period jumps to 15 seconds. That’s a proper groundswell. The energy is still moderate at 247, but that long period will give you some nice, lined-up waves. Best on a point or reef, but a beach break might see it a bit too straight.
The real standout in the first week? Friday the 7th of August. The morning is glassy with a 3ft SSW swell, 18-second period, and combined energy jumping to 706. That’s proper moderate-to-strong energy. The waves will have some real push and shape. Get out early before the afternoon cross-on ruins it.
The second week starts to show some promise. Saturday the 8th of August has a glassy morning again, 4ft at 16 seconds, and energy at 752. That’s a solid, clean session. Sunday the 9th is similar but with a touch less energy.
Now, keep your eyes on Friday the 14th of August. That morning is looking excellent. A 4ft SSW swell, 18 seconds, glassy as, and combined energy is a massive 1315. That’s strong wave energy. The waves will be powerful and lined up. It’s a bit more than 5ft, so it’s getting into the intermediate-to-expert zone. The period is over 15 seconds, so it’s a very long-period groundswell. That’s gonna be cranking on the points and reefs. Saturday the 15th of August is almost as good, with 5ft and energy at 1136, glassy again. These two mornings are the real standouts of the whole outlook. They’re a week away, so keep an eye on the charts, but it’s looking promising.
Bottom line: most mornings are clean, but the swell is small for the first week. The second week has a couple of absolute crackers. Get out on the 7th, 14th, and 15th of August if you can.
Rusty.

Information about the Costa Sol Surf forecast
The above surf forecast table for Costa 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 Sol can be found by selecting the local surf guide option on the grey menu. Our Costa 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 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 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.
Costa Sol is 27 km (17 miles) from Atoyac de Alvarez. If you plan a holiday in Guerrero, look for hotels and other accommodation in Atoyac de Alvarez. Atoyac de Alvarez has rooms for a wide range of budgets as well as car hire and transport links.
