The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a single spot lighting up the 16-day window: Playa Negra. This is a consistent, exposed break that handles a west-northwest swell best, and it’s suited for advanced surfers.
The water is sitting at 86°F right now, which is a full 4°F warmer than usual for this time of year. That’s notable – the ocean has a soupy, tropical feel to it.
The first real surf on offer kicks off Thursday afternoon, 6th of August. It’s small, with 2ft swell from the SW, but the wind is glassy. The combined energy is weak (110), so it’s not going to be punching, but it’ll be clean. Perfect for a longboard or a funboard if you’re just itching to get wet.
Friday morning the 7th sees a jump in quality. The swell is still modest at 2ft, but the period stretches way out to 18 seconds – that’s proper groundswell, lots of energy in the water. The wind is cross-off from the ENE at 16 mph, which will keep the surface clean. The combined energy climbs to 377. This is the kind of day where you’ll feel the ocean breathing.
Things really start to build over the weekend. Saturday morning, 8th August, is a standout. We’ve got 3ft of SSW swell, 16-second period, and a clean offshore breeze from the ENE at 12 mph. The energy is moderate (580), and the forecast is calling for very good surf conditions. This is about as good as it gets for the first week – punchy, clean, and lined up.
Sunday morning the 9th drops off a bit with a score that suggests marginal conditions, but Saturday afternoon remains a solid option with 4ft from the SW, 15-second period, and light cross-off wind. Clean, consistent, and fun.
The second week starts to show some promise too. Saturday morning, 15th August, is the real standout of the whole outlook. The swell hits 5ft from the SW with a 16-second period. The combined energy surges to 1117 – that’s strong wave energy. The wind is cross-off from the ENE at 16 mph. This is a big, powerful, clean swell. For experts only – 5ft is getting serious, and the energy is pumping. If you’ve got the skill, that’s the session to circle.
Sunday morning the 16th and Monday morning the 17th also hold clean, offshore conditions with 4ft to 4ft swell, good period, and cleaner winds. The energy stays in the moderate-to-strong range (764 and 521). Consistent, clean, and very surfable.
Later in the window, Wednesday afternoon the 19th looks interesting again – 3ft, 15-second period, glassy wind. The energy is moderate (502) and the conditions are clean. A glassy session is always worth chasing.
Overall, Playa Negra is the only game in town, but it’s a good one. The first week has a few smaller, clean days, but the second week – especially Saturday the 15th and Sunday the 16th – is where the real power shows up. Crowds are listed as “sometimes,” so you might share the peak, but with this variety of conditions, you can find a window.

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.
