The Lowdown
Alright folks, Rusty here. We’ve got a solid run of surf on the cards for Playa Negra over the next couple of weeks, so let’s get into it.
The first decent swell shows up on Thursday morning, September 3rd. It’s a sneaky one – a long-period groundswell from the SW, 19 seconds, pushing in at 2 ft. The wind is a clean cross-offshore from the ENE so the wave faces will be tidy. The combined energy is moderate (731). It’s small but super clean and the quality is there for a fun morning session.
Friday morning, September 4th, is the first real standout. We’ve got a jump in size to 5 ft from the SW, with a 17-second period. The wind is offshore from the ENE, only 6 mph. The combined energy is strong (1423). This is excellent for experienced surfers – the longer period and clean conditions will line up the point and reef beautifully. But it’s a bit punchy for beginners.
Saturday morning, September 5th, is another gem. The swell holds at 6 ft from the SW, period drops a touch to 16 seconds, but the wind? Glassy. Absolutely glassy. With a NE breeze at 3 mph, the surface will be like a mirror. Combined energy is strong (1578). This is the best session of the whole forecast for advanced surfers. The point will be firing.
Sunday morning, September 6th, is still promising with 5 ft from the SW and glassy conditions (ESE 3 mph), though the combined energy drops to moderate (847). Still a lovely morning surf.
The pattern continues into Monday, September 7th, with 4 ft from the SW and glassy conditions again. Clean, consistent, and fun. By Tuesday and Wednesday, the swell backs off to 2 ft – 3 ft, but the winds stay light offshore or glassy, keeping the waves clean. The combined energy is moderate (510 – 652).
So, for the first week, Saturday morning September 5th is the absolute standout. Bigger swell, glassy wind, and a long period SW groundswell. The break is a classic point and reef, so it’ll handle the long-period energy well. The water temperature is about average for this time of year, so no surprises there.
Moving into the second week, the energy drops. Thursday September 10th sees a moderate breeze (16 mph from the ENE) but still cross-offshore, with 4 ft from the SW. Friday September 11th is cleaner with a light offshore wind and 4 ft. Saturday September 12th is glassy in the morning with 4 ft, but the afternoon gets sloppy. By Sunday September 13th, the swell is down to 3 ft.
The end of the run, from September 14th onward, is small, with 2 ft – 3 ft, but several mornings are glassy. Wednesday September 16th has a glassy morning with 3 ft from the SW. The combined energy stays moderate (304 – 546). The afternoon winds turn onshore, so the early sessions are the go.
Overall, there’s plenty of surf here. Just remember that Playa Negra can get crowded, so get out early for the best waves. If you’re a beginner, stick to the smaller mornings (under 5 ft) when it’s glassy. The experts will be all over Saturday September 5th.

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.
