The Lowdown
Alright, Rusty here, and I’ve got the lowdown on the next couple of weeks for our little corner of the Pacific.
First up, we’re looking at a solid run of south-west groundswell hitting Playa Negra. The core of this swell is packing some serious grunt, with combined wave energy readings climbing into the four-digit figures (1413, 1578, 1650) through the middle of the week. That’s a lot of power in the water. The water temp is sitting right where it should be for this time of year, so no surprises there.
The real standout window kicks off on Friday morning, the 4th of September. We’ve got a clean 5ft swell from the SW, with a period of 17 seconds, and the wind is a light cross-off from the ENE at 6 mph. That’s a recipe for some beautiful, lined-up waves. The combined energy is a punchy 1413. This is proper advanced-level stuff – too much juice for beginners, but for the experienced crew, it’s going to be firing. The offshore wind is a major plus, keeping the faces clean and inviting.
The pattern holds into Saturday the 5th, with the morning session looking even meatier. A 6ft SW swell with a 16-second period, and the wind drops to a near-calm easterly breeze at just 3 mph. The energy level is still up at 1578. This is another top-tier morning for anyone who can handle it. The point will be handling this long-period groundswell beautifully, offering those long, wrapping walls. Keep an eye on the crowds though; Playa Negra can get busy, especially when the forecast is this good.
Sunday morning the 6th is still very good, with a 5ft SW swell and a clean offshore breeze from the ENE. The energy is a solid 879, but the swell period has dropped to 14 seconds, so the waves will be a little more manageable and more frequent.
After that, we see the swell slowly winding down through the week of the 7th. The mornings continue to offer clean, cross-off conditions, with waves ranging from 4ft down to 2ft. The wind stays light and favourable, making for fun, clean surf, but it’s not the same power as the first weekend.
The longest-range look, into the second week around the 14th and 15th, has smaller, clean 2ft to 3ft swells. The mornings are looking clean with offshore winds, and there’s even a glassy morning on the 17th. It’s small, but for a log or a fun mid-length, there will be some nice little peelers. The energy is down to the 200-400 range, so it’s about finesse, not power.
So, to wrap it up: the best on offer is the Friday morning and Saturday morning of the 4th and 5th September. That’s the big, clean, powerful stuff. The mornings in the following week are your best bet for smaller, cleaner conditions. The afternoons, especially with the risk of thunderstorms and the onshore sea-breeze kicking in, are mostly a write-off, so get your sessions in early.
This is Rusty, signing off.

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.
Playa Negra is 41 km (25 miles) from Nicoya. If you plan a holiday in Guanacaste, look for hotels and other accommodation in Nicoya. Nicoya has rooms for a wide range of budgets as well as car hire and transport links.
