The Lowdown
G’day, I’m Rusty. Alright, let’s have a proper look at what’s coming up for Playa Negra. We’ve got a pretty steady run of swell across the next couple of weeks, but don’t get too excited – a lot of it is on the smaller side and the winds tend to mess things up in the afternoons. This spot needs clean conditions to shine, and early mornings are definitely the go. The water is sitting at 86.2°F, which is a touch warmer than normal for this time of year, so you can leave the thick wetsuit at home.
The first solid opportunity kicks off Wednesday the 9th. Wednesday morning is looking clean with a moderate offshore breeze from the ENE at 15.5 mph, and a 2.6ft SW groundswell pumping in with a very long period of 16 seconds. The combined energy is moderate. It’s not big, but that offshore wind will make it glassy and fun for the advanced crew. Wednesday afternoon stays clean with a light breeze, but the swell only ticks up slightly to 3ft. It’s a nice start.
Thursday the 10th sees a bump in swell to 4.3ft from the SW, with a period of 17 seconds – proper groundswell energy now, and the combined energy is moderate. Thursday morning has a cross-off breeze from the ENE at 12.4 mph, keeping things reasonably clean. This is the best-looking swell size of the early run, but it’s still only shoulder-high. Thursday afternoon turns ugly with a cross-on breeze and a risk of thunderstorms – that’s a write-off.
Friday the 11th and Saturday the 12th hold similar small swells around 3ft to 3.9ft, with clean mornings and messy afternoons. The light offshore or cross-off winds in the mornings will offer some clean fun, but the wave energy is weak. Not a standout.
Sunday the 13th morning has a glassy feel with a slight offshore from the ESE at 3.1 mph, but the swell drops to just 2.3ft. It’s tiny but clean. A good day for a longboard.
Now, we hit a real quiet spell from the afternoon of Sunday the 13th right through to about Tuesday the 15th – the swell stays below 3.3ft, with cross-on winds and poor conditions. There’s a gap of a couple of days with nothing really worth paddling out for.
Things start to look up again on Tuesday the 15th morning. The swell jumps to 3.3ft from the SW, with a period of 17 seconds, combined energy moderate, and glassy offshore wind from the ESE at 3.1 mph. That’s clean, and the longer period means better-shaped waves. Wednesday the 16th and Thursday the 17th mornings follow the same pattern – 3.3ft swell, offshore or calm winds, clean conditions. Thursday afternoon even holds clean with a cross-off wind. These mornings are your best bet for a decent session.
And then, the standout of the whole outlook lands on Thursday the 24th of September. Swell pushes up to 5.2ft from the WSW, with a short period of 8 seconds – so it’s a windswell, not a groundswell, but the wind is completely glassy, zero wind in the morning. Combined energy is moderate. That 5.2ft with absolutely no wind will give you clean, punchy waves at Playa Negra. The short period means it might be a bit sectiony, but when it’s that glassy, you just don’t care. This is the one to circle on the calendar – best conditions of the whole 16 days by a long shot. It’s still over a week away, so keep an eye on it, but it’s looking promising.
Overall, the real highlights are the morning sessions from the 15th through the 17th, and that absolute gem on the 24th. Afternoons are mostly a write-off thanks to cross-on breezes and thunderstorms. This spot is an exposed beach and point, consistent for the advanced crew, and it catches plenty of SW swell. Crowds are possible here on the good days – it’s a well-known wave. If you’ve got a longboard, the tiny days will still be fun. For the bigger 5.2ft glassy morning, be ready, because that’s the one.

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.
