The Lowdown
Alright folks, this is Rusty checking in with a look at what’s coming down the pipe for the next couple of weeks. To be honest, things are looking pretty average for a while. No big, clean standouts popping up just yet, so we’ve got a bit of a wait on our hands.
The first few days are a bit of a write-off for getting really good waves. The swell is there, but it’s running into some issues. We’ve got a long-period groundswell coming in from the SW, which is the right direction for El Coco, but the wind is just too strong and gusty. Mornings see a fresh offshore breeze, which at least keeps the surface clean, but the wave quality is still being called marginal. The energy is moderate, swinging between 574 and 964 (moderate energy) points, but it's not translating into great shape.
Come Saturday the 5th and Sunday the 6th, the swell picks up a touch. Saturday morning we’re looking at 5ft of SW swell, still with that offshore wind, but the energy is building nicely to 1212 (strong energy). The period is sitting at 16 seconds, which is a solid groundswell, but it might be a bit too straight for the beachbreak here. It’s a better bet for the more experienced crew. The water is sitting at a warm 84°F, which is about normal for this time of year, so no surprises there.
The real standout, the one that’s got my attention, is way out there on Monday the 15th of September. We’ve got a very long period, 18-second, SW groundswell coming through, and the wind is going to be a dream. We’re looking at glassy conditions in the afternoon with zero wind. That’s a major positive for clean, lined-up waves. The swell is only 2ft, but with that long period, it’ll have plenty of push. The energy is 467 (moderate), but the quality will be way better than the numbers suggest. This is the one to circle on your calendar. It’s a promise, not a guarantee, but it’s the best thing on offer.
After that, the 18th of September also looks promising with a 21-second period, 2ft groundswell, and a moderate offshore wind. The energy is up to 671 (moderate), and it’s being flagged as “very good surf conditions.” That’s another one for the patient surfer.
So, short story: The first week is a grind with strong winds and mediocre surf. The second week, specifically the 15th and 18th, holds the real potential for clean, glassy or offshore sessions with that long-period groundswell. Keep your eyes on the forecast for those dates.
This is Rusty, signing off.

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.
