The Lowdown

G’day, Rusty here. Let’s talk about what’s coming up for the next couple of weeks at El Coco. It’s a mixed bag, but there are a couple of windows that’ll get you excited if you pick your days.

Right now, we’re kicking off on Sunday, the 6th of September with a bit of a slow start. There’s a SW swell running at 4.3ft, period around 14 seconds – so a solid groundswell – but the wind’s a fresh 15.5 mph from the ENE, which is offshore and keeping things clean. The combined energy is moderate at 760, and the water temp is sitting at 84.9°, about a degree warmer than average, so it’s a touch toastier than normal for this time of year. It’s not a standout though – the forecast flags some marginal conditions and the energy’s just okay for a beginner-friendly break. It’s fairly consistent, but crowds are possible here at El Coco.

Come Monday morning, the 7th, we drop a little to 3.6ft, still SW, with a 14-second period. Wind’s easing to 12.4 mph offshore, so it’s clean enough. Energy’s down to 497, so still moderate but not firing. This spot is exposed to the SSW, so that SW swell is lining up nicely for the take-off zone. Not a standout yet, but Monday afternoon sees a cross-shore breeze kick in from the SSE at 6.2 mph, and the swell fades to 3.0ft. Conditions go a bit choppy.

Tuesday the 8th sees the swell drop further to 2.6ft, period 13 seconds, with a stiff 21.7 mph offshore wind in the morning. Energy’s at 458 – still moderate – but the surf’s marginal and the wind’s strong, making it tough for a paddle session. Afternoon’s no better, cross-off wind and poor conditions.

We roll through the week with similar patterns: Wednesday the 9th has 2.3ft at 16 seconds, offshore wind at 21.7 mph, energy 418 – the period’s long but the height’s small. Thursday the 10th sees the swell nudge back up to 2.6ft in the morning, then 3.6ft in the afternoon, period 16 to 18 seconds, and energy climbing to 689. Wind’s cross-off from the ENE at 18.6 mph. It’s clean, but the forecast still calls it marginal. Friday the 11th offers 3.6ft in the morning, period 16 seconds, offshore at 18.6 mph, energy 677 – getting closer, but still not top-tier.

Now, the first real standout pops up on Monday, the 14th of September. Morning sees a tiny 1.6ft swell, but the period jumps to a massive 21 seconds – very long-period groundswell. That’s the kind of energy that wraps around points and reefs better than beach breaks, but El Coco is exposed, so expect clean lines if it hits right. Wind is offshore from the ENE at 12.4 mph, and the combined energy is 329, which is moderate but punchy for the size. The forecast rates it as “good surf conditions.” It’s a bit of a sneaky one – small but clean, and the period is special.

Tuesday the 15th builds on that: morning has 2.6ft at 18 seconds, wind offshore 15.5 mph, energy 472, and again “good surf conditions.” Afternoon pushes to 3.3ft at 18 seconds, energy 690 – this is the best of the first week. Clean, offshore winds, decent height, long period. The break is fairly consistent, and crowds are sometimes an issue, but with this quality, it’s worth the company.

Wednesday the 16th holds 3.0ft at 16 seconds, offshore 18.6 mph, energy 543 – still good, but the real magic is the morning of Saturday the 19th of September. Swell is 2.0ft at 20 seconds, wind is a light 3.1 mph from the north, cross-off, and the energy is 391. Forecast says “good surf conditions.” That’s a glassy morning with a very long-period groundswell – perfect for a beginner-friendly spot like El Coco.

Then Sunday the 20th of September morning: 2.3ft at 19 seconds, glassy conditions with a 3.1 mph ENE breeze. Energy 460. Again, “good surf conditions.” This is clean, mellow, and ideal.

But the true standout is Monday the 21st of September morning. Swell is 2.6ft at 18 seconds, glassy with a light 3.1 mph NE breeze. Combined energy hits 504, and the forecast rates it “very good surf conditions.” That’s the best call of the whole period – clean, glassy, long-period groundswell, moderate energy, and the wind is dead calm. For a break like El Coco, exposed to SSW swell, this lines up beautifully. It’s a Monday, so crowds might be lighter, though they’re sometimes an issue. This is the session to circle on your calendar.

A few gaps: after the 21st, the swell drops off, and the last few days are mostly marginal or poor

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.
