The Lowdown
Alright, let’s break down Playa Negra. This is a consistent spot for the advanced crew, and we’ve got a decent run of waves coming through, though you’ll have to be patient for the real magic. The water is sitting at a very warm 86°F, which is much warmer than normal for this time of year, so leave the thick rubber at home.
We kick off on Sunday the 13th. It’s small, with 2-foot swell from the SW. The energy is weak (191) and while the morning wind is a clean offshore from the ENE, the conditions are described as very ordinary. Monday the 14th is better, with the same 2-foot swell but a much longer 19-second period, pushing the energy up to a moderate 292. The wind stays clean, so it’s a good session for the logs.
Tuesday the 15th is where things start to build. The morning sees 2-foot SW swell with an 18-second period, and the energy jumps to a strong 515. With that gentle offshore breeze, it’s going to be clean. The afternoon gets a touch bigger at 3 feet and the energy climbs further to 696, but the wind swings cross-on, making it messy.
Wednesday the 16th morning is the first standout. We’ve got 4-foot SW groundswell, a 16-second period, and a massive energy reading of 830. A light offshore breeze keeps it glassy. This is proper, clean surf for the advanced guys. The afternoons turn cross-on, so get it early.
Thursday the 17th and Friday the 18th mornings stay clean with offshore winds and good energy, around 530 and 448 respectively. The swell drops slightly but the quality remains high. Saturday the 19th and Sunday the 20th see a drop in size, but Sunday the 20th morning is special: glassy conditions with 3-foot SW swell and a very long 19-second period, pushing energy to 738. This is another true standout – a long-period groundswell with no wind. It will be clean as a whistle, but with that period, expect the sets to be fat and walled at the beach, so it’ll be best on the point.
Moving into the second week, Monday the 22nd and Tuesday the 23rd mornings are clean with 3-foot and 3-foot swells respectively, and solid energy. Wednesday the 24th is glassy again. The real headline, however, is Saturday the 26th morning. The swell jumps to 7 feet from the SW with a 13-second period. The energy is an enormous 1612, and the wind is a moderate offshore from the ENE. This is for experts only – it’s powerful, heavy, and the kind of day that makes the whole run worthwhile. After that, it drops back to the 3-foot range with clean conditions into Sunday.
A few days at the very end, Monday the 28th, turn onshore and poor, so that's the tail end of the window.

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.
