The Lowdown
Alright folks, Rusty here with a look at what's shaping up for El Coco over the next couple of weeks.
Honestly, it’s a bit of a slow start. The beginning of this period is pretty quiet and not really worth paddling out for. The waves are small and weak, and the wind is howling out of the ENE at 22 mph. It’s offshore, which is good for the face, but it’s a strong breeze making it hard work. The water is sitting at a warm 85°, which is a touch warmer than normal for this time of year.
Things start to get interesting around Wednesday the 16th. We see the swell building slightly to 3 ft from the SW, and the wave energy is getting moderate. The wind is still a fresh offshore, keeping it clean, but it's a bit marginal for tide.
Now, the period that’s got my attention is the weekend of the 20th and 21st of September. Sunday the 20th is looking like a solid shout. We’ve got a clean 3 ft SW groundswell rolling in with a very long period of 19 seconds, giving the waves some real grunt and shape. The energy is strong, and the wind drops to a moderate offshore breeze from the NE. It’s a point break and reef setup, so that long period energy will wrap in nicely and offer up some good lines. Expect it to be consistent with decent shape. Monday the 21st holds similar size and quality, with that long period continuing.
If I had to call the standout, it would be Sunday the 20th. The combination of that long-period groundswell, moderate offshore winds, and strong wave energy points to the best surf on offer. It won’t be huge, but the quality should be there for a fun session.
Looking further out, the very end of the month shows a little pulse. The 26th of September sees a quick spike with a 6 ft wave from the WSW, but the period is a short 7 seconds, so it will be a bit jumbled. Then the 27th looks promising again with clean 3 ft SW swell and glassy conditions, another good option to keep an eye on. The long-range stuff is always a bit less certain, but it’s something to watch.

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.
