The Lowdown
Righto, let's get into it. This is Rusty, and I'm looking at the next two weeks for Tivives.
Overall, it’s a pretty slow and quiet outlook. The next week is mostly small, but there are a couple of windows where things line up. The real standout sits right at the very end of the window and is worth keeping an eye on if you’re patient.
We start off the 17th (Monday morning) with a glassy 2ft SSW groundswell, period a long 14 seconds, and the combined energy is weak at 287. It’s clean, but it’s tiny. That afternoon goes to junk with a cross-on wind, so the morning is your only shot that day.
Tuesday the 18th is similar – another glassy morning with 2ft SSW swell, then Tuesday afternoon actually shows a nice little spike in energy to 378 with a 2ft SW swell at 16 seconds and glassy conditions again. That’s a decent little window of clean surf.
Wednesday and Thursday (19th and 20th) are pretty ordinary with weak, short-period S swell around 2ft to 3ft. Nothing to get excited about.
Friday the 21st morning is the first real highlight. You get a 4ft S swell at 11 seconds with glassy, clean conditions. The energy is moderate at 337. That’s the pick of the first week. Morning session only though, as the wind shifts cross-on in the arvo.
We then hit a dry spell. Saturday the 22nd morning is glassy but only 3ft of short-period S swell, and then it’s mostly onshore junk or tiny surf right through until the 28th. Expect a lot of small, average days with onshore winds.
Then, on Saturday the 29th of August, the real one pops up. Saturday morning sees a 3ft SSW groundswell with a very long 17-second period, and the combined energy jumps to a solid moderate 433. The wind is glassy. This is groundswell with serious push for its size, and the long period will wrap in nicely at Tivives. The water temp is about average for this time of year. The only downside is the break is inconsistent, so you’ll need to be patient between sets, and crowds are possible here. The afternoon goes to shit with a cross-on, so it’s a dawn-patrol mission.
Sunday the 30th morning has similar sized swell (3ft, 16 seconds) and energy of 456, but the wind is a light cross-shore, so it won’t be as clean as Saturday morning. Still, it’s surfable.
The very last day, Monday the 31st of August, shows a glassy, calm morning with 3ft SSW swell and decent energy of 312. Another clean, small morning.
So, to wrap it up: if you can, Friday the 21st morning for the cleanest 3ft waves. But the best on offer is Saturday the 29th of August morning – that long-period SSW groundswell with glassy conditions is the standout. Get on it early.
Rusty.

Information about the Tivives Surf forecast
The above surf forecast table for Tivives provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Tivives can be found by selecting the local surf guide option on the grey menu. Our Tivives 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 (Tivives) 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 Tivives 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.
Tivives is 15 km (9 miles) from Esparza. If you plan a holiday in Golfo de Nicoya, look for hotels and other accommodation in Esparza. Esparza has rooms for a wide range of budgets as well as car hire and transport links.
