The Lowdown
Alright, this is Rusty here, lookin' at the next couple of weeks for Playa Negra.
Right off the bat, we’ve got a bit of a slow start to August. The first few days are mostly small and messy, nothing to get excited about. The real action starts to build from Friday the 7th onwards, with a nice run of cleaner, more energetic swell.
The water is a standout feature right now, sittin' at a balmy 86°F, which is a solid 4°F warmer than normal for this time of year. It’s like bathwater out there, so you can leave the thick wetsuit at home.
For the first half of the week, Monday the 3rd through Thursday the 6th, it’s a mixed bag of small, weak swell. We’re lookin' at ankle to knee-high waves, mostly around 1 ft to 3 ft from the SW, with combined energy readings that are weak (around 104 to 274). The winds are all over the place, switching from light cross-onshore to some clean offshore and glassy conditions on Thursday morning and afternoon. Thursday actually feels like the best of a bad lot, with a clean 2 ft swell and offshore wind in the morning, then going glassy in the afternoon. It’s surfable, but you’ll be working for scraps.
Then we hit Friday the 7th and the game changes. The combined energy jumps to 389, still moderate but with much more punch. The morning brings a clean 2 ft SSW groundswell with a period of 18 seconds. That’s proper long-period energy, perfect for a point like Playa Negra, drawing nice lines. The wind is a clean cross-offshore from the NE. It’s a solid morning session.
But the real standout, the one you want to circle on the calendar, is Saturday the 8th and Sunday the 9th. Saturday morning has a 3 ft SSW swell from a 16-second period, with combined energy hitting 585 (moderate wave energy). The wind is light and cross-offshore from the ENE, making for pristine conditions. Then Saturday afternoon the swell bumps up to 4 ft from the SW, the period drops to 15 seconds, and the wind goes glassy. That’s a recipe for the best waves of the forecast period. The energy is strong at 515. Sunday holds it together with a clean 3 ft swell and light offshore winds. These two days are the pick of the bunch.
The following week, from Monday the 10th through to the 18th, the swell hangs in there but gets a bit more inconsistent. We’ve got pulses of 3 ft to 4 ft SW swell, with periods ranging from 14 to 18 seconds. The combined energy swings from moderate (around 327) to strong (963 on Friday the 14th). The morning windows are often clean with cross-offshore winds, but the afternoons get chopped up by onshore breezes. The best of the second week looks like Friday the 14th and Saturday the 15th, with a 4 ft to 4 ft SW groundswell and clean conditions in the mornings. The energy is strong (over 900 on those days), so it’ll have some grunt, but it’s not huge. For a more advanced break like this, it’s a great window. Just be aware that the afternoon winds can ruin the party.
Overall, get in the water from Friday the 7th through the weekend for the cleanest, most consistent waves. The second week has some promising morning sessions, but the window is tighter.
Rusty.

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.
