The Lowdown
Alright, let’s talk about the next 16 days at Cocles. The first few days are a bit of a slow start, but things start to get interesting by Sunday morning the 16th. Water temperature is 84°F, about normal for this time of year, so nothing to worry about.
The real standout is Sunday morning, August 16th. Cocles is a beach and reef break, very consistent, and open to the NE. That morning we’ve got a 8ft ENE swell with an 11-second period, combined energy of 1555 (strong to very strong). That’s proper groundswell, and with a light W breeze making it cross-off, the conditions are clean. This is for experienced surfers—it’s solid, powerful, and the long period gives you some nice gaps between sets. The direction is a bit shy of the ideal NE, but it’s still pumping.
Before that, Friday the 14th is a dud—small, weak, and onshore. Saturday the 15th gets a bit of size but the wind is messy, cross-shore and cross-on, so it’s just marginal. Then Sunday morning hits, and it’s the best of the whole run.
After Sunday, the week of the 17th to the 23rd sees a steady drop in swell size. Monday the 17th morning is still worth a session—6ft NE with glassy conditions, clean, and moderate energy (539). That’s a good one for a solid intermediate. Tuesday and Wednesday mornings stay glassy, with size dropping to 5ft and 4ft, but the wind is dead calm, so it’s clean and fun.
Thursday the 20th and Friday the 21st are average—small swell, and Friday afternoon gets choppy with a cross-on. The weekend of the 22nd and 23rd brings a slight rebound, but the swell is only 4ft to 5ft, with a short period around 8 to 9 seconds. The wind is manageable, especially Sunday morning the 23rd with glassy conditions.
Into the second week, from the 24th onward, it’s a bit of a flat spell. Swell is small, mostly 4ft to 5ft, and the wind often turns cross-on or onshore. There are a few clean windows—like Thursday morning the 27th with glassy conditions and a 5ft ENE swell—but nothing that really stands out. The last few days, the 28th and 29th, are small and messy, with cross-on winds and low energy.
So, if you’re picking one session, go for Sunday morning, August 16th. That’s the one to circle. After that, hit the clean mornings when the wind is light or glassy, and you’ll score some fun, smaller waves.

Information about the Cocles Surf forecast
The above surf forecast table for Cocles provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cocles can be found by selecting the local surf guide option on the grey menu. Our Cocles 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 (Cocles) 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 Cocles 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.
Cocles is 35 km (22 miles) from the city of Changuinola. If you plan a holiday in Limon, look for hotels and other accommodation in Changuinola. Changuinola has rooms for a wide range of budgets as well as car hire and transport links.
