Table - best surf conditions forecast for Tamarindo over the next 16 days.
Hey, Rusty here. Let’s break down what’s coming for the next couple of weeks. We’ve got a long spell of small, steady swell, with some glassy sessions that’ll make the most of it. The water’s sitting at a warm 86°, which is a touch warmer than normal for this time of year, so you’ll be fine in boardshorts.
The main event of the whole run is Tamarindo (a river mouth). It’s consistent and catches swell well. The absolute best window looks like Saturday the 25th of July. You’ve got a 0.8m swell from the SSW, with a very long period of 21 seconds. The combined energy is pumping hard at 790 – that’s a lot of punch for a small wave. That long-period groundswell will roll in, and with the morning offshore wind from the E at 6 mph, it’ll be clean. Sets will be spread out, but the shape will be proper. Crowds are often here, so expect some company.
Right from the start, Friday afternoon the 10th of July is a solid opener. SSW swell at 0.8m with a 15-second period, and the wind goes glassy from the SSE at 3 mph. Combined energy is 387, so there’s moderate juice in the water. Clean and inviting.
Saturday the 11th keeps it rolling. The morning has a cross-off breeze from the NE, with 0.9m SSW swell and a 15-second period. The afternoon turns glassy from the WNW at 3 mph, with the same 0.9m swell and energy jumping to 448. That afternoon will be silky.
Sunday the 12th stays clean with cross-off winds, 0.9m SW swell and a 14-second period. Consistent fun-size waves.
The week stays consistent and clean. Monday morning the 13th has 0.7m SW swell with a cross-off breeze, and Tuesday morning the 14th turns offshore from the ENE at 9 mph with 0.6m SW swell. Energy drops, but it’s still rideable.
Friday the 17th of July has another standout afternoon. Glassy from the E at 3 mph, with 0.9m SSW swell and a 13-second period. Energy is 431, and it’ll be a clean afternoon for ripping.
Looking ahead, Sunday the 19th of July afternoon turns glassy from the SSE at 3 mph, with 0.6m SW swell from an 18-second period. Energy is 217 – small but clean.
Monday the 20th of July afternoon has offshore wind from the ENE at 3 mph, with 0.8m SW swell and a 16-second period. Energy is 384, and it’ll be clean.
Wednesday the 22nd of July is worth a look. The swell bumps to 1.4m from the SW, but the period drops to a short 8 seconds. The morning has a cross-off from the NNE at 6 mph, and the afternoon turns offshore from the ENE at 16 mph. With energy at 496, there’s push, but the short period makes it a bit lumpy – still fun.
The real prize, as I said, is Saturday morning the 25th of July. Offshore E wind at 6 mph, 0.8m SW swell with a 21-second period, and energy at a massive 790. That’s the one to circle.
There are a few gaps, like Wednesday afternoon the 15th where it goes onshore and poor, and some mornings later in the run that look ordinary. But overall, Tamarindo delivers consistent swell and plenty of glassy windows to keep the stoke alive. The long-period swells will favor the river mouth, giving you better shape than a beach break.
Rusty.

Information about the Tamarindo Surf forecast
The above surf forecast table for Tamarindo provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Tamarindo can be found by selecting the local surf guide option on the grey menu. Our Tamarindo 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 (Tamarindo) 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 Tamarindo 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.
Tamarindo is 46 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.
