The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Tamarindo over the next couple of weeks.
Right off the bat, the first few days are gonna be a bit of a struggle. Thursday the 16th and Friday the 17th are looking pretty flat and weak, with a bit of a lumpy cross-off breeze making things feel even messier. The water temp is 86°, which is a touch warmer than normal for this time of year, so you won’t need a wetsuit, that’s for sure.
The real action doesn’t start to fire up until Saturday the 24th. That’s a good week away, so keep it in the back of your mind. We’ve got a solid pulse of long-period groundswell coming in from the SW, with a period of 24 seconds. That’s some serious energy (812 combined energy). Saturday morning the 24th is looking like a standout with 3ft swell, clean conditions, and a light breeze. This is the kind of day where the river mouth at Tamarindo will start to show its lines, especially with that long period swell wrapping in. Just be aware, long period stuff like that can make beach breaks a bit straight, but here it’ll work nicely.
The next true standout is Sunday the 26th. The morning is glassy – dead calm – with 4ft of SW groundswell and a period of 19 seconds. The energy is pumping at 1104. This is excellent for experienced surfers, but if you’re a beginner, it might be a bit much. The water will be clean as a whistle, and the sets will have real power.
Monday the 27th morning is also top-tier. 5ft of SW swell, 19 seconds, and a light offshore from the ENE. That’s 1487 combined energy – the biggest we’ll see. This is a proper session, but again, for the more experienced crew. The river mouth will be handling it well.
Tuesday the 28th morning keeps the trend going with 5ft of SW swell, still clean and cross-off. That’s a big wave for the area, so only experts should be out there. After that, the swell starts to back off towards the end of the month, but the mornings on the 30th and 31st still offer some clean, glassy waves in the 3ft to 3ft range, which is perfect for everyone.
The only real crowds issue here is that Tamarindo is often busy, so expect company, especially on the standout days. The wind is mostly cross-off or offshore throughout, which is a major positive. Overall, the second week is where you want to plan your trip. The first week is a write-off.
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.
