The Lowdown

Alright folks, Rusty here, giving you the lowdown.

We’ve got a solid run of surf on the horizon, starting this Monday. Early on, the water is sitting at 86°F, which is a good 4°F warmer than usual for this time of year. That’s noticeably warmer than your typical September water.

The standout of the whole period is hands down Thursday the 10th. Playa Negra is the call. We’re looking at a solid 4ft of swell from the SW, packing a punch with a combined energy reading of 1110. That’s some serious push. The period is a steady 17 seconds, so it’s proper groundswell. This spot is a beach-and-point break, so that long period energy should wrap in nicely. With a clean, offshore ENE breeze at 9 mph on the morning of the 10th, it's going to be clean and powerful. This one is for the advanced crew, though – 4ft with that energy is no joke for the beginners.

Leading up to that, the week starts a bit smaller. Monday morning is also a good call. 4ft from the SW, 14-second period, and a light cross-off breeze from the NE at just 3 mph. Combined energy is sitting at 542, so it's moderate but clean, and the water is still that 86°F.

Tuesday morning (the 8th) , the swell drops a bit to 2ft, but the period stretches to 18 seconds. With an offshore breeze from the E, it will be clean, just smaller. The energy is still moderate at 625.

Wednesday (the 9th) is a solid day with clean conditions both morning and afternoon. 3–3ft from the SW, period dropping to 16 seconds, but the wind is offshore and light. On Wednesday afternoon it goes glassy with a cross-off breeze.

After the Thursday highlight, we fade into a smaller, less consistent stretch. The mornings generally offer cleaner conditions with cross-off or offshore breezes, but the afternoons turn into a mess with onshore winds and storm risks. The swell stays in the 2ft to 4ft range, but the consistency drops and the combined energy falls off into the 200–700 range.

Sunday the 14th morning is worth a mention for the glassy conditions. The swell is tiny at 1ft with 17-second period, but if you've got a longboard and patience, it will be completely smooth. Glassy conditions and 178 energy is a quiet winner.

From the 17th onwards, the pattern continues with cleaner mornings and blown-out afternoons. There’s a window on Friday the 18th morning with 3ft swell and glassy conditions, and again on Sunday the 20th morning with 2ft and glassy wind. A couple of late-period pulses show up around the 19th and 20th with 20–21 second periods, but the swell size is small and the wind is mostly onshore or cross-on, so it's not going to be the same quality as the earlier week.

In short: the first week has the magic. Thursday the 10th is the one to circle. The second week is for the dedicated few who can pick the clean morning windows.

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.
