The Lowdown
## Imperial
Alright folks, let’s break down the next couple of weeks at El Estero—the only game in town.
Thursday 13th August afternoon you’ll find a clean 3ft southwest groundswell, with a long 15-second period. The water’s a touch warmer than normal at 86°, and a light cross-off breeze from the east-northeast keeps it smooth. Moderate energy at 409.
Friday 14th morning pumps up to 4ft with an extra-long 18-second period – that’s real juice. Combined energy jumps to 901 (strong). Clean again. The Friday afternoon gets tricky though, with a light cross-shore wind from the south-southwest putting some bumps on the surface.
The real standout is Saturday 15th August afternoon. A clean 5ft southwest swell, 16-second period, and a pure offshore wind from the east at 9 mph. Glassy, powerful, and smooth. Energy is 1002 (very strong). This is for the experienced crew – best session of the window.
Sunday 16th fades, with a fresher breeze messing up the afternoon. By Monday 17th we get a tiny clean window with a glassy northwesterly breeze and a 4ft swell.
Then the doldrums hit. From Tuesday 18th afternoon through Saturday 22nd morning, it’s mostly poor – onshore wind, weak energy, and messy conditions. Not worth the paddle.
Things improve Saturday 22nd afternoon with a clean 2ft swell and offshore wind. Sunday 23rd morning also small but clean at 2ft with a very long 19-second period – longboard territory.
Monday 24th afternoon turns glassy, and Tuesday 25th morning offers a clean offshore window, both with tiny 2ft swells.
And looking way ahead to Friday 28th August morning – about a week and a half out – we see a promising bump: 4ft, 17-second period, light offshore, and strong energy at 894. One to watch, but not a guarantee.
The crown jewel is Saturday afternoon. Everything else is small and scattered.
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.
