The Lowdown
Alright folks, Rusty here with a look at what the next couple of weeks are gonna serve up for Tamarindo.
We’ve got a bit of a mixed bag coming our way. The week starts with some decent energy, but it’s not a perfect run by any means. The stand-out period looks to be the first few days, particularly Wednesday the 29th and Thursday the 30th of July.
Wednesday morning, July 29, is your best bet for the entire outlook. Tamarindo (a river mouth setup) will be seeing a solid 5 ft groundswell from the SW with a very long period of 16 seconds. That’s a lot of energy in the water – we’re talking a combined energy of 1232 (moderate to strong), and with a clean, cross-off NE breeze at 9 mph, it’s going to be well-shaped. That 16-second period is a proper groundswell, and you’ll feel the lulls between sets, making the paddle out a bit easier. The water temp is about average for this time of year. Just be aware, this is a spot for experienced surfers at this size, and the long-period swell can sometimes make a river mouth a bit weird, but the wind is clean.
Thursday morning, July 30, is the next one worth setting the alarm for. The swell drops a notch to 4 ft from the SW, period at 14 seconds. Still a good groundswell. The wind turns offshore from the ENE at 16 mph, which is a bit breezy but it’ll be clean and groomed. The combined energy is still a solid 675 (moderate). It’ll be a little punchier than Wednesday, but with offshore wind, the shape should be nice.
.
After that, the sizes start to drop off. Friday and Saturday mornings are surfable with clean conditions, but the swell is down around the 3 ft mark or less. Brace for a flat spell from around Sunday, August 3, through the start of the following week – there’s a gap of several days where the surf just doesn’t have much to offer.
Look ahead to the second week. Saturday morning, August 8, shows a glimmer of hope with a 2 ft SW groundswell (16-second period) and light offshore wind – glassy conditions. The combined energy is 405 (moderate). It’s small but clean.
Then, the most promising long-range signal comes in on Wednesday morning, August 12. We’ve got a 3 ft SW groundswell with an even longer 18-second period and a moderate offshore ENE breeze. The combined energy jumps to 534 (moderate). It’s over a week away, so don’t book your flights yet, but the ingredients are there for a clean, fun morning if the swell fills in a bit more.
So, for the short term, Wednesday the 29th and Thursday the 30th of July are the clear standouts. For the long shot, keep an eye on Wednesday, August 12. The crowds can be an issue here, so get out early.
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.
