The Lowdown
Alright folks, Rusty here. Let’s talk about the next couple of weeks at Playa Negra.
We’ve got a solid run of surf on the horizon. The first week kicks off with some proper energy, a real standout window for the experienced crew. The water temp is sitting about average for this time of year, so nothing crazy to report there.
Friday the 4th: morning is where it’s at. There’s a clean, solid 1.5m SW groundswell, with a period of 17 seconds, pushing some serious energy (1413). That’s a lot of power – over 8ft on the face for sure, so this is strictly for the experts. The wind is light and offshore from the east, making for some beautiful, lined-up waves. Afternoon goes a bit cross-onshore and messy, so get out early.
Saturday the 5th: Another cracker morning. 1.7m SW swell, 16-second period, and 1446 units of energy. Again, this is expert territory with that much juice. Clean offshore wind from the east-northeast. Afternoon has the chance of a storm and cross-onshore wind, so morning is the only call.
Sunday the 6th: Still some very good, clean surf in the morning. The swell drops a touch to 1.4m, but that’s still a strong wave. Light offshore wind again. The energy is starting to back off into the moderate range (878).
Monday the 7th: This is a beauty of a morning. Wave height is down to a more manageable 1.1m, but get this – it’s glassy. Zero wind. The swell is clean, the surface is like a mirror. This is the pick for the whole run if you want a proper session without getting absolutely smashed.
After this, the swell slowly fades through the middle of the week but stays clean with offshore or light cross-off winds. From Tuesday the 8th through Thursday the 10th, you’ve got waist to chest-high SW swell with clean conditions. That Thursday morning the 10th has a moderate offshore breeze, which will hold the face up nicely.
The second week is a lot smaller and less consistent. From the 11th onwards, it’s mostly smaller, cleaner waves for the longboard or a fun mid-length, but with a few tricky tide windows. Saturday the 14th has a glassy morning on a long-period 19-second swell, but it’s only 0.6m – a real slow, clean longboard wave. By the 17th and 18th, the swell tries to pick up again, but it gets a bit tricky with cross-shore winds.
There are a few days with no real standout surf, particularly around the 14th and 15th where the swell just isn’t offering much energy. It’s worth checking the tides.
Overall, the absolute standouts are Friday morning the 4th, Saturday morning the 5th, and that glassy Monday morning the 7th. If you only have one window, make it Monday the 7th for the cleanest, most user-friendly conditions.

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.
