Alright, let's switch it up for the imperial folks. This is Rusty.
So, for the upcoming stretch at Tamarindo, we're looking at a pretty solid run of clean, small waves. The water’s warm, coming in at 87°F, a bit warmer than usual, so it’s boardies and a rash guard weather.
The kick-off is Saturday afternoon the 4th with a clean offshore breeze and 3ft swell from the SSW. It’s a consistent groundswell with a 15-second period, so it’ll have some nice energy (401).
Sunday morning the 5th stays clean and light, with 2ft waves, but Sunday afternoon gets blown out. Now, Monday the 6th is the real highlight of the first week. Monday morning is glassy with a 2ft swell, but the period jumps to 20 seconds – that’s very long-period groundswell. The combined energy is a healthy 775, so those sets will have some serious welly. It'll wrap around the river mouth nicely.
Through the rest of the week, wave heights sit between 3ft and 5ft, but those afternoon cross-onshore winds and storm risks shut it down fast. Keep your eye on Tuesday morning the 7th: a clean 4ft swell with a cross-offshore breeze, but it's still a long-period setup, so expect lulls.
Saturday morning the 11th is another cracker – 3ft, true offshore wind, and super clean. Perfect for a log or a fun shape.
Things get small from the 13th through the 18th, with a pretty flat stretch. Waves drop to 1ft to 2ft with low energy (down to 89), so it's mostly for beginners and longboards until we get a glimpse of something better.
That better thing is Sunday the 19th – over a week away, but the afternoon looks glassy with calm wind and a clean 3ft swell. The energy jumps back up to 604. If that forecast holds, it’ll be a real beauty of a session. Crowds are always a thing here, so be ready for company.
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.
