The Lowdown
Alright, let’s get into it. The next couple of weeks are pretty quiet to start, but there’s a real pulse of energy coming through for the second weekend. We’re looking at a building southwest swell, and if the timing lines up, we could see some proper stand-up waves.
The water’s running about 86°, which is a couple of degrees warmer than what we’d usually expect this time of year. You’ll feel that difference as soon as you paddle out.
We start things off on Tuesday the 4th. It’s small, with a knee-high 2ft of southwest swell and a 13-second period. The wind is light out of the ENE, so it’s clean, but honestly, it’s pretty flat and ordinary. Not worth getting too excited about. The afternoon gets a bit messy with a cross-on breeze and some storm clouds around, so we’ll give that a miss.
Wednesday the 5th is more of the same – small, 2ft swell, clean morning but not much push. The afternoon drops off. Thursday the 6th is a touch better with a little more consistency, but we’re still talking about ankle-biters. The mornings are your best bet for a clean surface.
Now, hold on. Friday the 7th is when things start to wake up. The swell jumps to 2ft, but the period stretches out to 18 seconds, and the energy in the water jumps to 377. That’s a real pulse of groundswell. The morning has a light cross-off breeze, and by the afternoon, it goes glassy. That’s a nice window for a longboard or a fish. The waves will be lined up and clean, even if the size is still modest.
Saturday the 8th sees the swell building a bit more, up to 3ft. The energy is climbing into the 500s, which is a healthy amount of push. The morning has a bit more wind, but it’s still offshore. The afternoon gets a little cross-shore, but it’s manageable. It’s a step up from the previous days, but the tide might be a bit iffy.
Sunday the 9th is a good one. The swell holds at 3ft, but the period stays in the 14-second range, and the energy is solid. The wind is a clean offshore from the ENE at 25 km/h in the morning, which is going to make the conditions nice and clean. Both sessions look good, with the morning being the pick for that offshore texture.
Monday the 10th drops off a touch, and the afternoon gets chopped up by a cross-on breeze. We’re back to smaller, less interesting surf.
Tuesday the 11th is a mixed bag. The morning has a clean 3ft with a light offshore wind, which is worth a look. But the afternoon? The swell energy jumps to 763, but the wind swings onshore and makes it messy. It’s a classic case of the ocean having all the power but the wind ruining the party.
Wednesday the 12th and Thursday the 13th are similar – small, clean mornings, but nothing that’s going to get your heart racing. The energy is still there, but the size is limited.
Okay, here’s where it gets interesting. Friday the 14th. The swell is starting to build for real. The period is 18 seconds, and the energy is pushing 963. The morning is still a bit marginal, but the afternoon is looking proper. The swell is 4ft, the wind is a light cross-off from the SE, and the forecast says “very good.” This is the first day that’s really worth planning for.
But the real standout is Saturday the 15th. This is the day. The swell bumps up to 5ft with a 16-second period, and the energy is over 1100 – that’s a strong, powerful swell. The morning is clean, but the afternoon is the money shot. The wind goes offshore from the E at 20 km/h, and the report says “excellent surf conditions for experienced surfers.” This is the one to circle. At 5ft, it’s starting to get some size, so it’s not for the groms, but for anyone who charges, this is proper Playa Negra. The WNW swell direction is right in the wheelhouse for this break, so it should be hollow and fast.
Sunday the 16th is still good, with 4ft of 15-second swell, but the wind gets strong in the afternoon with a fresh breeze from the ENE. The morning is still clean, but the magic of Saturday is gone.
After that, we’re back to average. Monday the 17th has a fresh breeze that makes things messy, but the rest of the week sees a return to 3-4ft swell with clean mornings and onshore afternoons. It’s surfable, but nothing special.
So, to sum it up: if you want waves, you’re waiting for the 14th and especially the 15th. That’s the standout window. The rest is a classic small, clean summer run. Don’t bother with the board until then.

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.
