The Lowdown
Alright, Rusty here. Let's take a look at what's cookin' for the next couple of weeks.
First up, we've got Playa Negra. The water's sitting at 86.4°, which is a touch warmer than normal for this time of year, so you might not need the thickest wetsuit.
Right off the bat, Sunday morning the 6th is looking promising. We've got a solid 4.6ft swell rolling in from the southwest, with a period of 14 seconds – that's some proper groundswell energy. The wind is glassy, coming in from the southeast at just 3 mph, which means the surface is going to be smooth as butter. The combined energy is sitting at 855 (moderate), and this is a consistent, exposed break that handles a WNW swell best, so the direction is working in our favor. This is a standout session for advanced surfers.
The pattern holds through Monday morning the 7th. The swell drops a touch to 3.6ft, but still from the southwest with a 14-second period. The wind shifts to a cross-off from the southeast at 9 mph, keeping things clean. Energy is at 542 (moderate). This is another solid morning session.
Tuesday morning the 8th sees the swell drop to 2.3ft, but don't write it off. The period jumps to 18 seconds – that's a very long-period groundswell, meaning the waves will have plenty of push and shape. The wind is a cross-off from the east-northeast at 9 mph, keeping the surface clean. Energy is 650 (moderate). This is a good call for a point break or reef setup, but at a beach break like this, the long period might make it a bit straight. Still, it's worth a paddle.
Wednesday morning the 9th is another clean one. Swell at 2.6ft from the southwest with a 16-second period. Wind is offshore from the east at 9 mph, and the energy is 674 (moderate). The offshore breeze will be your best friend here.
Now, Thursday morning the 10th is the real standout of the whole run. Swell builds back up to 4.3ft from the southwest, period at 17 seconds – long-period groundswell. The wind is offshore from the east-northeast at 12 mph, creating clean, lined-up waves. The combined energy jumps to 1094 (strong). This is excellent surf for experienced surfers. If you can only get out one day, make it this morning.
Friday morning the 11th is still good. Swell at 3.9ft from the southwest, 16-second period, cross-off wind from the east-northeast at 9 mph. Energy is 754 (moderate). Clean conditions continue.
After that, things start to taper off. Saturday the 12th morning has 3.3ft swell from the southwest, 14-second period, with a light cross-off breeze from the east-northeast. Energy is 407 (moderate). It's still good, but not as punchy.
Sunday the 13th morning is small, with 2.3ft swell, but the wind is offshore from the east at 3 mph. Energy is 222 (weak). It's clean, but tiny.
Monday the 14th morning is almost flat with 2.0ft, but the period is a whopping 21 seconds – very long period. The wind is glassy from the north at 3 mph. Energy is 421 (moderate). This is a weird one; the energy is there, but the wave height is so small it's hard to get excited. The long period might give you a few clean lines if you're on the right break.
Tuesday the 15th morning picks up a bit, with 3.3ft from the southwest, 18-second period, and glassy wind from the east at 3 mph. Energy is 761 (moderate). This is a good morning for a clean, glassy session.
Wednesday the 16th morning has 3.6ft from the southwest, 16-second period, with offshore wind from the east-northeast at 6 mph. Energy is 655 (moderate). Clean again.
Thursday the 17th morning is 3.3ft from the southwest, 14-second period, glassy wind from the east at 3 mph. Energy is 426 (moderate). Another good, clean morning.
The second week sees smaller, cleaner conditions. Friday the 18th morning has 2.6ft from the southwest, 13-second period, with a cross-off breeze from the southeast at 3 mph. Energy is 416 (moderate). It's clean, but small.
Saturday the 19th morning is tiny, with 2.0ft from the southwest, but the period is 20 seconds. Glassy wind from the north-northeast at 3 mph. Energy is 452 (moderate). Long period, small waves –

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.
