The Lowdown
Alright folks, Rusty here. Let’s take a look at what we’ve got cooking for the next couple of weeks.
The whole window is centered on one spot – El Estero. There’s a bit of a wait for the good stuff to line up, but once it does, we’re in for a proper run. The pattern starts to build from Saturday the 25th with a solid, long-period groundswell that has some real grunt, and it hangs around in a big way through the middle of next week. The energy is strong, and the wind is playing ball on most mornings.
The standout window is undoubtedly Sunday afternoon the 26th through to Tuesday morning the 28th. Sunday afternoon is the real gem: we’re looking at a clean 4ft swell from the SW with a period of 18 seconds, and the wind goes glassy. That’s a recipe for perfection at this river mouth – the long period will wrap in nicely, and the lack of wind will make it silky smooth. The combined energy is sitting at a solid 1099, so there’s plenty of push.
Monday the 27th keeps the fun going in the morning with a 4ft SW swell and a clean cross-off breeze. It’s a step down from the glassy session, but still a ripper. Tuesday morning the 28th is the biggest of the lot, with the swell hitting 6ft from the SW, and a clean, light offshore breeze. That’s a solid, powerful wave – definitely one for the experienced crew, as it’s getting up there in size. The energy is a beastly 1766. After that, the swell slowly winds down through the rest of the week.
By the end of the first week and into the second, the energy drops off. We get a few clean mornings with smaller, long-period swell (around 2ft to 3ft), but nothing that’ll get the pulse racing. A highlight in the second week is Friday morning the 7th of August: a clean 3ft SSW groundswell with a very long 18-second period, and barely a breath of wind. The energy is a respectable 755. That’s a promising one, but being that far out, keep an eye on the forecast.
The water temp is about average for the time of year, so no surprises there.
The crowds at El Estero? They’re a factor. The file says it’s “often” busy, so expect company, especially on those peak days.
So, to sum it up: the magic is this weekend through early next week. If you can only pick one slot, make it Sunday afternoon the 26th for that glassy, long-period gold. Tuesday morning for the bigger, more powerful stuff. After that, it’s picky mornings for the more patient surfer.
Rusty.

Information about the El Estero Surf forecast
The above surf forecast table for El Estero provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at El Estero can be found by selecting the local surf guide option on the grey menu. Our El Estero 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 Estero) 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 Estero 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 Estero is 47 km (29 miles) from Nicoya. If you plan a holiday in Guanacaste, look for hotels and other accommodation in Nicoya. Nicoya has rooms for a wide range of budgets as well as car hire and transport links.
