The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the table for the next couple of weeks.

We’re kicking off a slow start, but the pattern builds into some real gems later on. The first few days, from Sunday the 23rd to Wednesday the 27th of August, are pretty average. The swell is small, mostly around 2ft to 2ft from the SW, with a long period of 15 to 19 seconds. That’s a groundswell, but the energy is weak to moderate (300 to 129). You’ll find some clean windows, especially Monday afternoon when it goes glassy, but the wave height is just too small to get excited about. It’s a waiting game.

The first proper standout kicks off on the morning of Thursday the 28th of August. The swell picks up and the combined energy ramps up to 705. It’s still a bit messy, but by Friday afternoon the 28th, the energy is moderate (514) and the wind is clean. It’s building towards something.

Then, Saturday the 29th of August. The morning session at Playa Negra is the real deal. We’re looking at 5ft of SW swell with a period of 16 seconds. The combined energy is strong at 1193. The wind is offshore from the ENE, making for a clean, lined-up wave. This is excellent for experienced surfers. The water is warm, sitting at 86°F, which is a touch warmer than normal for this time of year. The crowds are a possibility here, so don’t expect a solo mission. The afternoon gets a cross-on wind, so the morning is the window.

Sunday the 30th is still solid, with 5ft swell but the period drops to 14 seconds and the energy is still strong (935). The wind is clean in the morning. Monday the 31st fades a bit back to 4ft.

Now, for the long-range promise. The big one is Friday the 4th of September. The morning at Playa Negra is a proper heavy swell. 6ft of SW groundswell with a period of 17 seconds, and the combined energy is very strong at 2061. The wind is glassy, dead calm. This is an expert-only zone. The wave will be powerful and relentless. It’s a long way out, so keep an eye on it, but if it holds, that’s the session of the outlook.

Saturday the 5th of September morning is also a standout, with 6ft of SW swell and offshore wind, energy at 1950. Another expert-level day. The pattern holds through the 6th and 7th with smaller, but still fun, clean waves.

So, overall: the first week is small and quiet. The best on offer is the Saturday morning of the 29th of August, and the potential heavy hitter on Friday the 4th of September morning. Get out there for those.

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.
