The Lowdown
Alright, Rusty here, let's talk surf. We've got one main spot on the radar for this outlook: Playa Negra. The water's sitting at 86°F, which is a touch warmer than normal for this time of year, something you'll feel on that first paddle out.
We're looking at a solid week ahead, starting Saturday, September 5th. The standout session of the whole run is hands-down Saturday morning. We've got a solid 6ft SW groundswell pumping in with a very long 16-second period, packing a strong energy reading of 1459. The wind is a clean cross-off from the ENE at 9 mph. This is prime Playa Negra territory – that long-period groundswell loves a point and reef setup like this. It's going to be powerful and lined up, but at this size, it's strictly for advanced surfers.
The energy drops a notch into Sunday, September 6th, with 5ft SW swell, but the conditions turn glassy in the morning with a light 3 mph offshore from the east. That’ll be a joy to surf, clean as a whistle, with moderate energy (847) and plenty of fun left on the table.
Into the new week, Monday, September 7th sees the swell easing to 4ft, but we’ve got a moderate cross-off breeze keeping things rideable. Then a real treat pops up on Thursday, September 10th. The morning session brings a punchy 4ft SW swell with a 17-second period, energy kicking back up to 1094. The wind is a proper offshore from the ENE at 12 mph. This is another premium window for experienced surfers, with clean, groomed faces.
After that, the swell settles into the 2ft to 4ft range for the rest of the first week and into the second, with mostly clean morning windows. The standouts in the second week are Wednesday, September 16th morning with 3ft SW and light offshore wind, and then Friday, September 18th morning, when it goes glassy with a tiny 2ft SW swell, but that period stretches to a very long 21 seconds. It won't be big, but those long-period lines will be peeling slow and clean if you're on a log or a fish.
Keep an eye on the afternoons though – the wind tends to swing onshore from the SW or SSW, and combined with the risk of thunderstorms, the surf gets chopped up. The morning windows are your golden hours here.
So, bottom line: Saturday the 5th and Thursday the 10th are the top-tier sessions for the crew who can handle it. The rest of the week offers plenty of fun, clean morning waves for everyone else. After that, the second week is quieter but still has those glassy moments worth chasing.
Rusty out.

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.
