The Lowdown
Alright, grab your board, let’s talk about what’s on the radar. It’s not going to be a week of barrels, but there are definitely some windows where Playa Negra is gonna turn it on. This is a consistent break, but it’s a fickle one too, so you gotta pick your moments.
First up, Thursday the 10th and Friday the 11th. We’ve got some SW groundswell at 4ft to 4ft, but it's a bit on the messy side. The mornings are clean, but the afternoon seabreeze kicks in. It’s surfable, but don't expect perfection; we're getting a touch more energy in the water with readings around 1094 and 838 on Thursday. The water is 86°, which is a touch warmer than normal for this time of year, so it’s a bit of a warm bath out there.
The weekend drops off. Saturday the 12th fades to 3ft, and it gets a bit stormy in the afternoon, which just chops everything up. We're looking at a couple of days of small, weak surf through the 13th and 14th, with energy readings dipping into the low hundreds. Sunday and Monday are pretty much a write-off unless you just want to get wet on a longboard.
Things start to perk up again on Tuesday the 15th. The morning looks good, and then that afternoon is a standout. The wind goes glassy and we see 3ft of SW swell with energy climbing to 696. That’s when you want to be out there. It’s not big, but it’s clean and will be super fun on the point.
The first week’s highlight, though, is Wednesday the 16th morning. The swell bumps up to 4ft with 16 second period, and we’ve got a nice offshore wind. Energy is at 760. This is looking like the best of the first week.
Now, into the second week, don't get too excited. We’re looking at smaller surf, mostly in the 3ft range with some good periods. There’s a real standout in the mix though. Thursday the 17th morning is glassy with a solid 3ft SW swell, and then again on Sunday the 20th, the morning is glassy with 3ft, but the period jumps to 19 seconds. That’s some long-range energy that should wrap into the point nicely.
Also keep an eye out for Monday the 21st morning. We see 4ft of SW swell and the winds are glassy. That’s another good clean window. But as we get later into the month, the storms start to threaten the afternoons, so the mornings are going to be key. This is a good spot for a longboard or a fish, it’s not going to be a heavy day.
Overall, the best bet is those clean mornings. For me, the standout is Wednesday the 16th morning – the swell is up a touch, it’s offshore and consistent, and the energy is solid. The second big one would be Tuesday the 15th afternoon when it goes glassy.
Alright, that’s the look. The forecast can always change, so keep an eye on it. Could be better, could be worse, but there’s enough here to get you in the water.

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.
