The Lowdown
Right, grab a coffee and listen up. This is Rusty, checking in with the outlook for Playa Negra. It’s a beach and point setup that’s consistent and exposed to the west-northwest, and it’s mainly an advanced wave.
We’ve got a bit of a slow burner to start. The first real action worth paddling out for is on Friday afternoon, 28 August. The swell is a clean 2 ft from the southwest, period around 19 seconds, and the wind swings offshore from the east. That’s a gentle offshore breeze and clean conditions. The combined energy is moderate (518). It’s not huge, but it’s a solid start to the weekend.
The standout window kicks off Saturday, 29 August. The morning pushes 5 ft of southwest groundswell with a 16-second period, and the wind is offshore from the east-northeast. The combined energy is strong (1230). This is the pick of the first week: excellent conditions for experienced surfers, with clean faces and proper power. The afternoon stays 5 ft but the wind shifts south, becoming cross-offshore, so still surfable but less clean.
Sunday, 30 August drops a little to 5 ft, but the period backs off to 14 seconds. The morning is clean with a moderate cross-off breeze. The energy is still strong (991). It’s solid but not the standout.
Then we get a lull mid-week. Monday 31 August through Wednesday 2 September sees the swell drop under 4 ft with shorter periods. The wind turns cross-onshore or variable, and the combined energy weakens into the hundreds. It’s marginal—don’t waste the petrol.
Thursday 3 September is flat and messy. Keep the board in the van.
Now, the second week brings a real spike. Friday, 4 September has a 5 ft southwest swell, 17-second period, and a light offshore from the east-northeast in the morning. The combined energy jumps to very strong (1429). That’s excellent for the advanced crew again. The afternoon gets a risk of thunderstorms and a cross-onshore wind, so get your session in early.
Saturday, 5 September is almost a repeat: 5 ft, 16 seconds, light offshore from the east-northeast in the morning. Combined energy is 1360. The morning is clean and excellent. This is the second true standout of the entire 16-day window.
After that, Sunday 6 September through Friday 11 September the swell slowly drops from 4 ft down to 3 ft, with period fading from 14 to 15 seconds. Winds are mostly light or glassy in the mornings—especially Tuesday 8 September and Wednesday 9 September with glassy conditions and a 2 ft to 4 ft swell. These are clean, fun waves for the experienced crowd, but the energy is moderate (543–883). Not the size of the earlier standouts, but clean and consistent.
The week closes out Friday 11 September with a 4 ft clean swell and a glassy afternoon. Surfable right to the end.
A couple of notes: The water temperature is running around 86°F, which is a touch warmer than normal for this time of year—nothing crazy but noticeable when you’re sweating in a shorty. The swell here is long-period groundswell most days (14–19 seconds), so it will draw up nicely on the point setup. At the beach sections, that long period can make waves sectiony, but Playa Negra handles it well.
Crowds are sometimes an issue here, so pick your tides and be ready to share.
Overall, ignore the early flatness. The real deals are Saturday 29 August morning and Friday 4 September and Saturday 5 September mornings. Those are the ones to circle on the calendar.

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.
