The Lowdown
Alright folks, Rusty here. Let's have a look at what we've got coming down the line for our little corner of the coast.
We’re looking at a pretty solid run of surf ahead. The water is sitting at a warm 86°, which is a touch warmer than normal for this time of year, so you can leave the thick rubber at home. The real standout is going to be this Saturday afternoon, the 29th of August. We’ve got a solid 5ft groundswell rolling in from the SW with a long 16-second period. The combined energy is pumping hard at (1314) and with a cross-off breeze, it’s going to be clean. This is excellent, but it’s a solid size for an advanced break, so know your limits.
Sunday morning, the 30th, still has some size at 5ft from the SW, but the tide or conditions look iffy so it's not the pick. The afternoon brings a risk of thunderstorms and a cross-on wind, so it’s a write-off.
Monday, the 31st, drops back a touch. The morning has 4ft SW swell with a NE cross-off breeze making for clean conditions. It’s a decent option. The afternoon gets messy again with southerly cross-winds.
Tuesday, the 1st of September, is a classic early session. The morning is clean with 3ft SW swell and an offshore breeze out of the east. It’s not huge, but it’ll be fun. The afternoon falls apart with a southerly moderate breeze.
Wednesday the 2nd is a morning glass-off special. Only 2ft, but that’s a long 18-second period SW groundswell and the wind is glassy with a combined energy of (589). For a smaller board, this will be silky smooth. Thursday the 3rd is a repeat: glassy morning with 3ft and a 16-second period.
Now, here’s the next big one. Friday the 4th of September morning fires up again. We’re looking at 5ft SW swell, 17-second period, offshore wind from the ENE, and the energy jumps to (1457). That’s excellent for experienced surfers. Clean and powerful.
Saturday the 5th keeps it going. The morning has 6ft SW swell, the biggest of the run, with a 16-second period and a light cross-off breeze. Energy is at (1577). This is a proper swell. It’s getting into that expert-only territory though, so be careful. The afternoons are all plagued by afternoon storm risk and cross-on winds through this period, so the early bird gets the worm.
The following week settles down a bit. Sunday the 6th has 5ft with glassy morning conditions. Nice. There’s a gap of a few days here where the conditions get mixed up with wind and storms, but we get another good morning on Tuesday the 8th and Thursday the 10th with clean 3ft+ SW swells. The Friday the 11th morning has a nice 4ft with a 16-second period and offshore wind.
The final weekend, Saturday the 12th and Sunday the 13th, looks like it’ll fizzle out. The 12th morning has glassy 4ft, but the energy drops to (514), and the 13th is just tiny.
Overall, the absolute best on offer are the Saturday 29th afternoon, the Friday 4th morning, and the Saturday 5th morning. Big, clean, and powerful. Don't sleep on that Wednesday the 2nd morning glass-off either if you like it silky.
Stay safe out there.
Rusty.

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.
