The Lowdown
Alright, Rusty here. Let’s take a look at what’s cooking at Playa Negra.
Alright, so things are gonna start off a bit slow and messy this morning. We’ve got a clean-looking wave but the wind is howling cross-off at 19 mph and the whole setup is just poor right now. Not one to paddle out for. But stick around because Sunday afternoon is where it starts to turn. The wind backs off to a solid offshore breeze at 9 mph, and we get a 3 ft SW swell with a long 14-second period. It’s clean, it’s got shape, and the combined energy is moderate (415). It’s a good surf session for the more advanced crew.
Monday comes in similar – the mornings are blown out by a fresh cross-off, but both afternoons have clean, offshore conditions with waist-to-chest high waves. The energy stays moderate. Tuesday morning is a cross-off but still clean, though the swell is a little smaller. Tuesday afternoon gets a bit ugly with a cross-on wind and some storm risk, so that’s a pass.
Wednesday the 12th looks better in the morning: offshore wind, clean, 2 ft but with a nice long 16-second period. A bit small but very clean. The afternoons are a write-off with onshore winds and t-storms.
Thursday the 13th is just ordinary – messy and cross-off/ onshore chop. Not worth a mention.
Now, Friday the 14th afternoon is the first real standout. The swell bumps up to a clean 4 ft from the SW, long 18-second period, and the wind goes light and offshore from the southeast. Combined energy is strong (1097). This is excellent surf for experienced surfers at Playa Negra. The waves will have real push and shape, and with light wind, it’ll be glassy. Crowds are possible here, so get on it early.
Saturday the 15th morning is solid but a bit dicey for the less experienced – the swell hits 5 ft, with strong cross-off winds (16 mph) making it a challenge. The afternoon is much cleaner with offshore wind and the swell dropping to 4 ft – very good, but it’s a moderate breeze so not as perfect as Friday. Sunday the 16th keeps the clean, 4 ft waves going with light winds. Solid weekend.
Monday the 17th is a drop-off in energy, but Tuesday the 18th morning is a beauty – glassy conditions, 4 ft SW swell, combined energy at a moderate 541. A very clean, fun session for anyone.
Wednesday the 19th morning is another strong option: 6 ft from the SSW, but with a shorter 9-second period. The wind is offshore and clean, making it a good wave, but that size is pushing into expert territory. In the afternoon, it goes onshore and junky.
Thursday the 20th morning is still clean with 4 ft and offshore wind, but the energy drops. After that, the surf fades into small, weak, blown-out junk through to Saturday the 22nd. There’s a gap of a few days with very little to recommend.
Then we get a late burst: Sunday the 23rd is a proper standout. Morning has a clean 3 ft SW swell, long 20-second period, and glassy offshore wind. Combined energy is moderate (537). Then Sunday afternoon turns glassy with a light SSE breeze – super clean, long period, but the swell is small. It won’t be big, but for the wave quality and the conditions, this is a beautiful session for the experienced surfer who knows Playa Negra. The water temp is about average for this time of year, nothing unusual.
Monday the 24th morning keeps up the offshore flow with 3 ft and an 18-second period. Clean, but small.
Overall, the best bets are Friday 14th afternoon and Sunday 23rd. The Friday is bigger and has strong energy with clean conditions – a real session. The Sunday is smaller but glassy and pristine. Both are for advanced surfers. Mid-week, Tuesday the 18th morning is a sleeper pick for the glassy clean waves.

Information about the Playa Negra Surf forecast
The above surf forecast table for Playa Negra provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Playa Negra can be found by selecting the local surf guide option on the grey menu. Our Playa Negra 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 (Playa Negra) 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 Playa Negra 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.
Playa Negra is 41 km (25 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.
