The Lowdown
Alright folks, Rusty here with a look at what we’ve got cooking for the next couple of weeks. We’re looking at a run that has its moments, but you’ll need to pick your windows.
The main event is Tivives. It’s a fairly exposed SW spot that’s inconsistent, so when it lines up, it’s worth a look. Right now the water is sitting at 86°, which is a touch warmer than normal for this time of year.
The forecast kicks off this Friday morning, September 4th. We’ve got a solid SW groundswell running at 3 ft with a long 17-second period, and the combined energy of all swells is pumping in at a healthy 517. That’s moderate wave energy, but with that long period, this isn’t really a beach break – it needs a better-shaped bank like Tivives to make it work. The conditions are dead clean with glassy conditions and a light WNW breeze. This is the standout period, with a second pulse on Saturday morning also delivering 3 ft SSW swell and glassy winds. The quality is right, the waves have some genuine push, and the wind is off. If you’ve got a board with you, Friday or Saturday morning is the call.
By Sunday morning (September 6th), the swell drops back to 3 ft with a 15-second period and the energy eases to 373. Still clean, but it’s settling down. From Monday (September 7th) through to Thursday (September 10th) the surf drops right off into the 1 ft to 2 ft range. The longer period holds (14–18 seconds), but you’re really scraping for any power at those sizes. That said, Thursday morning (September 10th) looks promising with another pulse of 3 ft SW swell at 18 seconds and glassy conditions – combined energy hits 445. That’s our second standout window. The early mornings are where it’s at; by afternoon each day, winds turn onshore and chop things up.
There’s a notable gap of small, weak swell from around September 12th through to September 16th. Very weak energy levels under 200 in places – not worth getting wet over. The waves are there but tiny, with inconsistent, bypassing energy.
Looking further out, the period from September 17th to the 19th sees a new long-period SW groundswell arrive. The morning of Thursday the 17th has 1 ft but with a 23-second period – that’s a very long groundswell. Combined swell energy is 297. The 18th morning looks similar with 1 ft at 21 seconds. With those periods, the power is in the water, but the height is marginal. That setup is more for the reefs and points, not a beach break. It could provide a few clean runners for the patient surfer – but it’s a long-range call, so don’t lock it in just yet.
So to sum it up: the best bet is Friday morning at Tivives. Glassy, solid long-period SSW swell, moderate energy, and that inconsistent reef setup just might fire. Saturday is a solid backup. Keep an eye on Thursday the 10th too for a secondary pulse. The middle of the month will be a struggle, and while the very end of the window looks interesting, it’s a wait-and-see.
Rusty out.

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.
