The Lowdown
Alright, Rusty here. Let’s break it down.
We’ve got a decent run shaping up at Playa Negra, a beach and point setup that’s exposed to the WNW swell. The water is sitting at 86°, which is a touch warmer than normal for this time of year, so you’ll feel that extra bit of warmth in the water. This spot is for advanced surfers only, and it’s consistent, so you know it’ll be working.
The first few days are a bit of a slow burn. Tuesday the 25th and Wednesday the 26th have small swell around 2ft to 2ft, but the wind is messy and the energy is weak (245 down to 111). Not worth stressing over. Thursday the 27th is still small, but the swell period jumps to 18 seconds, giving it some life. The energy is moderate (270) and the morning is clean with a light breeze. It’s small but clean.
Friday the 28th is a bit of a tease. The morning has a fresh breeze and a 3ft swell with a 19-second period, but the energy is moderate (787). The wind is cross-offshore, so it’s clean, but the swell is just too weak for much. The afternoon gets better with a slight air and clean conditions.
Now, the standout. Saturday the 29th morning is the real deal. We’ve got a 5ft SW swell with a 16-second period, and the energy is strong (1230). The wind is offshore from the east at 15 km/h (9 mph), giving you gentle offshore and clean waves. This is excellent for experienced surfers. The afternoon gets a bit messy with a cross-onshore wind, so make the most of the morning.
Sunday the 30th morning is still good, with 5ft swell and offshore winds, but the energy drops a bit (911). It’s clean and very good. Afternoon turns onshore again. Monday the 31st is still in the 4ft zone, clean in the morning, but the wind shifts and the afternoon gets cross-shore and choppy.
Tuesday the 1st of September and Wednesday the 2nd drop back to 3ft and 2ft, but Wednesday the 2nd morning is glassy. The swell period is 18 seconds, so the energy is moderate (568), but it’ll be a glassy, clean little session.
Thursday the 3rd is another glassy morning, with 3ft at 16 seconds and moderate energy (501). The afternoon turns cross-shore. Friday the 4th morning is a proper standout: 5ft SW swell, 17-second period, strong energy (1246), and offshore wind from the east at 10 km/h (6 mph). Excellent for experienced surfers. The afternoon is onshore and choppy.
Saturday the 5th morning is also excellent, with 6ft SW swell, 16-second period, and strong energy (1439). The wind is offshore and light. The afternoon turns glassy, with 6ft and zero wind, making it another excellent session. That Saturday is a double-header.
The second week rolls on with Sunday the 6th and Monday the 7th offering clean, offshore mornings with 5ft and 4ft swells, moderate energy, and glassy conditions on Monday. Tuesday the 8th and Wednesday the 9th keep the 3ft to 4ft swell going, with clean mornings and long-period energy. Wednesday the 9th morning has an 18-second period with moderate energy (818) and offshore wind.
Overall, the best bets are Saturday the 29th morning and Saturday the 5th morning, with Friday the 4th morning also being a top pick. The first week has a slow start, but from the 29th onward, it gets good. The second week is more consistent but smaller, with clean mornings being the key.
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.
