The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the table for the next couple of weeks.
First up, we’ve got a long stretch of clean, offshore wind with a persistent southwest groundswell, but the energy just isn’t there to get too excited about for a while. The water temp is sitting at 85° – a touch warmer than normal for this time of year, so it’s a bit of a bath out there.
The early mornings are your best bet, with a fresh offshore breeze from the ENE keeping the surface clean. Surf size is small – we’re talking waist-high to maybe a touch bigger at best, with swell heights mostly hanging around 2ft to 4ft and a nice long period of 16 to 18 seconds, which means the waves will have good shape but the sets will be spaced out. This will be best for a longboard or a funboard, and it’s a good time for beginners at El Coco, which is exposed to the SW and breaks fairly consistently.
From Thursday the 10th through to Thursday the 17th, it’s marginal. The morning windows have that fresh offshore wind, but the scores just aren't there. The combined swell energy is weak to moderate, sitting between 251 and 737 (moderate energy) – it’s there, but just not enough spark. Afternoons are a write-off with cross-off or onshore winds.
The real standout window arrives on Monday the 18th of September. That morning is looking *glassy* – dead calm with light easterly winds and a clean 3ft SW swell. The combined energy is moderate at 404. This is a rare moment of actual glassy conditions, and it’s worth dragging yourself out of bed for. The break should be clean and peel nicely.
Then, if you can wait, Friday the 25th of September looks like the best day on the whole chart. We see the swell jump up to 5ft with a short period of just 7 seconds – so it’s a bit weaker and choppier in shape, but the offshore breeze from the ENE will keep it clean. The combined energy climbs to a strong 629 (moderate-high energy). This is the biggest surf of the window and it'll be clean, so this is the one to circle for the experts and strong intermediates. That afternoon also cleans up nicely with a cross-off breeze and a very long-period 21 second southwest swell creating some beautiful lines, but likely only 2ft. That 734 combined energy reading is strong, and the shape will be incredible for a point or reef – though at a beach break it might break a bit straight.
Bottom line: The first week and a half is small but clean for logging. The 18th morning is a glassy treat, and the 25th is the proper swell window.

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.
