The Lowdown
Alright folks, Rusty here. Let's get into what's happening at El Coco.
Right off the bat, I gotta be straight with you – the next week or so is looking pretty weak. We've got a small, long-period groundswell coming from the southwest, but the energy just isn't there. The combined wave energy is sitting in the low hundreds, barely cracking 589 (moderate energy) on the 16th and then just fading. For most of this run, it's a marginal call at best. You'll see some 3 ft to 4 ft swell from the SW with periods around 14 to 15 seconds, which is that classic long-period groundswell. That means nice shaped waves, good energy *if it shows*, but long waits between sets. For a beachbreak like El Coco, that long period can make ‘em break a bit too straight, so don't expect perfection.
The wind is the real story here. It's blowing offshore from the ENE nearly the whole time, 18 to 22 miles per hour, sometimes stronger. That's a fresh to strong breeze, and while it will hold the waves up clean, it's going to be a battle to paddle into anything. It's clean, but it's not easy. The water temp is 84°F with a 1° anomaly – that's dead average for this time of year, so no surprises there.
From Sunday the 16th through to the 29th of August, it's mostly just poor or marginal. We get a little bump on the afternoon of the 28th and into the 29th, with the swell coming back up to 3 ft from the SW and the energy climbing back to 541 (moderate energy). Still, the wind is cross-off or onshore-ish, so not the best. It’s a long wait for anything decent.
Now, the standout. You want to circle Sunday morning, the 30th of August. We've got a 3 ft SW swell with a 14-second period, combined energy of 408 (moderate), and here's the kicker – the wind drops to a moderate offshore breeze from the ENE at 12 miles per hour. That is the best wind of the whole run. The forecast is calling for "moderate offshore and clean," which I think is the only time in this 16-day window you'll get truly good conditions. The waves won't be massive, but they'll be clean and surfable for a beginner to intermediate. It's the pick of the bunch, no question.
Overall, the surf's on life support for a while, but that Sunday the 30th really stands out as the morning to get wet. It's a long-range call, so keep an eye on it, but it's the best hope we've got.
Rusty.

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.
El Coco is 12 km (7 miles) from San Juan del Sur. If you plan a holiday in Rivas Province, look for hotels and other accommodation in San Juan del Sur. San Juan del Sur has rooms for a wide range of budgets as well as car hire and transport links.
