The Lowdown
Alright, let's talk surf in feet and miles per hour. We're looking at Playa Negra for the next 16 days. It's a classic beach-and-point that lights up on a west-northwest swell.
So Wednesday the 12th kicks things off real slow. We got a tiny 2ft swell from the southwest, but it has a super long period of 16 seconds – that's proper groundswell. The energy is weak though (347 combined). Wind is a moderate cross-off, so it's clean, but you'll be scratching for any ride.
Things get a bit more interesting Thursday afternoon the 13th. The swell bumps to 3ft from the southwest, still with a long 15-second period. The big news is a light offshore wind from the east-southeast, which will put a real nice face on the waves. The energy is a moderate 415. This is the first real sign of life.
Friday the 14th: the swell builds to 4ft from the southwest, with a very long period of 18 seconds. That's a lot of power. Morning winds are a moderate cross-off keeping it tidy, with the energy already strong at 919. By afternoon, the wind swings to a gentle cross-on, the energy cranks up to 1139, and it gets a bit bumpy. Plenty of push for the experienced guys, but the wind messes with the shape.
The standout is Saturday the 15th. The morning sees a consistent 5ft swell from the southwest at 16 seconds, clean under a gentle cross-off wind, with a strong energy reading of 1118. But the afternoon is where it's at. We’re looking at 5ft swell, still from the southwest, the wind drops to a light cross-off, and the energy stays strong at 1001. The conditions are dialed for experienced surfers. That's the session to clear your schedule for. The swell direction is a bit south of its ideal, but the size, power, and clean conditions make it the clear winner. A 5 to 5ft wave can be a handful for beginners.
Sunday the 16th settles into a solid 4ft to 5ft with a 15-second period. Light cross-off winds keep it clean. Energy is still in the moderate to strong range (677-606). It's a very good day, just not the peak of Saturday.
Through next week, from Monday the 17th to Tuesday the 18th, the swell drops to around 4ft. The period shortens to 14 seconds. Tuesday afternoon is a real gem though – glassy conditions with a 3ft southwest swell. You'll be surfing on a mirror.
The second week, from the 19th onward, the swell really fades. We're talking ankle to knee-high, mostly 2ft to 2ft. The periods are all over the place, with some very long 18 to 19-second groundswells on the 23rd and 24th, but no size behind them. The energy drops to weak values (109-328). There are a few clean windows with offshore or glassy winds on the mornings of the 20th and 23rd, so you might snag a fun little runner, but don't bank on it. The afternoons get chopped by onshore wind.
There's a real dry spell from about the 21st to the 22nd, and then just very weak, marginal conditions until the 27th, where we see a small pulse of 3ft from the southwest with a great 18-second period and clean winds on Thursday morning. That one is a long way out, so treat it as a promising whisper.
The bottom line: Saturday the 15th is the day. Make it happen.

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.
