The Lowdown
G’day, it’s Rusty. We’ve got a solid run of surf ahead at El Estero, a consistent river mouth break that’s exposed to the swell and picks up a nice range of south-west groundswells. The water temp is sitting pretty much average for this time of year, so no surprises there. The standout morning is Saturday 8 August. That’s the pick of the first week: a clean 3ft swell from the south-southwest with a 16-second period, light offshore wind from the east-northeast, and combined wave energy already hitting 580 – that’s moderate energy, but the offshore wind and long period mean the lines will be clean and pushy. It’s a good one for intermediates, with the river mouth shaping up nicely. Crowds are often here, so get in early. The other real highlight comes later: Tuesday 11 August afternoon. The wind goes glassy, the swell holds at 3ft from the southwest with a long 18-second period, and the energy jumps to 643 – moderate but with plenty of punch. Perfect for a late session. Sunday 9 August afternoon also goes glassy with 3ft southwest swell – that’s a solid runner-up. The first week has a few messy afternoons with cross-onshore wind, but most mornings clean up nicely. Looking into the second week, Friday 14 August morning brings a 3ft southwest swell, 19-second period, and offshore wind – the energy hits 515. Promising. Saturday 15 August afternoon looks good too: 4ft southwest swell, 16-second period, offshore wind, and energy at 643. And Sunday 16 August afternoon goes glassy with 3ft southwest swell and 547 energy. The long-range stuff is promising but less certain. Overall, there’s surf nearly every day here, with the best conditions falling on those glassy morning windows. If you’re after a real standout, lock in Saturday 8 August morning.

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.
