The Lowdown
Alright, I’m gonna level with you. Right now, the surf is pretty quiet across the region, but there’s a little window of fun to be had if you’re patient. Let’s break it down.
Things start off slow. The first real recommendation doesn’t roll in until Monday, August 17th, so that’s a gap of a few days with nothing worth getting out of bed for. From Monday morning, El Coco starts to show some life. The water temp is sitting at 84°, which is about 1° warmer than average for this time of year – nothing crazy, just a touch on the warm side.
Monday morning at El Coco, we’ve got a solid 3ft swell from the SW, with a 14-second period. The energy is moderate at 447, and the wind is offshore from the ENE at 12 mph, keeping things clean. It’s a good call for a beginner-friendly wave, though it’s fairly consistent, so you’ll get a few in. The afternoon holds up too, with similar conditions. That’s your best bet for the early part of the week.
Tuesday, August 18th, sees a slight drop in size to 3ft, but the wind stays offshore in the afternoon, making for clean, rideable waves. The energy dips a bit to 396, but it’s still solid for a learner or a longboarder.
Now, let’s talk about the standout. The real highlight is the morning of Saturday, August 29th. By then, the swell picks back up to 3ft from the SW, with a 16-second period, and the energy is moderate at 614. The wind is cross-off from the ENE at 19 mph, so it’ll be clean. This is the best on offer in the whole 16-day window – a nice, consistent groundswell that’ll have some punch. Just keep in mind that long-period swells like this (16 seconds) can break a bit straight at beach breaks, but El Coco is exposed and handles it well. Crowds are possible here, so get in early.
The rest of the month is a bit of a mixed bag. The second week sees smaller swells, mostly 1ft to 3ft, with periods dropping off. The wind stays mostly cross-off or offshore, but the energy is weak, usually under 300. Not much to get excited about.
Overall, Monday and Tuesday next week are your go-to for a clean, easy session, and Saturday, August 29th, is the one to circle on the calendar if you want a bit more size and power.

Information about the El Coco Surf forecast
The above surf forecast table for El Coco provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at El Coco can be found by selecting the local surf guide option on the grey menu. Our El Coco 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 (El Coco) 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 El Coco 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.
