Nosara Surf Forecast Guide

Nosara is a surf destination located along the Guanacaste Coast, covering much of the Nicoya Peninsula in Costa Rica. This area is known for its dry climate due to the strong Papagayo winds that blow for about half the year. The main surfing area in Nosara is Playa Guiones, which offers a wide-open beach setup that attracts surfers looking for consistent waves. The beach stretches for about two miles, providing plenty of space to find your spot, but be mindful of the locals and the crowd, especially during the busy summer season.

The surf at Nosara can be pretty good, especially when the swell is coming from the south or southwest. It handles swell sizes from around 5 ft to 7 ft (1.5 to 2.1 meters) at mid to high tide, and the waves can vary from beach breaks to point breaks. Expect both lefts and rights, giving options for different types of riders. The bottom is mostly sand, which helps create some nice waves, but there are also rock formations you should be aware of. This spot is suitable for all skill levels, from beginners to experts; just make sure to pick your time and spot wisely to enjoy yourself.

Access to the beach is straightforward, with informal parking along the road leading to Playa Guiones. The town has made efforts to keep the first section of the beach undeveloped to help protect the coastline's nature. Despite the crowd factor, especially during peak seasons like spring and summer, the vibe at Playa Guiones is generally friendly, and most surfers are happy to share waves. There's a mix of shortboards, funboards, longboards, and even fish or bodyboards being used here. Keep an eye on the wind, which is usually best from the northeast to east, to ensure a fun day out on the water.

Confidence

Confidence tells you how much the weather models agree on the forecast.

  • High confidence: Models agree closely; forecast is reliable.
  • Medium confidence: Some disagreement; conditions may shift slightly.
  • Low confidence: Models diverge; treat forecast with caution.

We calculate the wind confidence by comparing wind speed, gust and direction from multiple models (like GFS, ECMWF, Arome, and Harmonie) and seeing how closely they match. For wave certainty we compare height, period and direction, also on multiple models. They are weighted, meaning that some models count more than others, depending on how good they are for a certain spot.

Readme

Welcome! If youโ€™re new to surf forecasting, check out this quick guide.

Forecast Table

The forecast table (the section on the page with all the numbers) is designed to pack as much information in the screen as possible. Although intimidating at first, it will help you make informed decisions about the waves faster, trust me :D. The table consists of roughly four sections, time and predictions, wind, waves, and tides:

๐Ÿ”ฎ Time and predictions section

Here we show the forecast thour and the overall surf quality prediction. This is determined based on the wave, wind and tide quality prediction. These individual predictions can be found on the forecast map.

๐Ÿ’จ Wind section

The first row on the table (with the ๐Ÿ’จ icon) shows wind speed, direction and gust. The more the wind speed the more aggressive the color (from blue, green, orange to red).

๐ŸŒŠ Wave section

The waves section consists of three rows, one for wave height and direction, one for period and one for wave energy. Our algorithm chooses the "dominant wave" using spot-adjusted surf energy (depth + directional fit). This is usually the first swell partition, but during local storms it can switch to wind waves. If that happens, values are shown in gray and italic.

๐ŸŒ’ Tide section

The tide section consists of a row with the actual heights per hour (measured at the half hour) and a table that displays the flow of the tide and the extremes (lows and highs).

Forecast map

The forecast map consists of arrows. These arrows represent all wave partitions (swell partitions and wind wave partition) and the wind. This allows you to see things like: a secondary swell or wind waves messes up the surf, or the wind is just a tick offshore so very surfable. Click a metric label in the bottom left to bring that arrow to the front โ€” handy when arrows overlap.

Forecast Cheat Sheet

Short on time? Focus on wave energy. Itโ€™s the best single metric to gauge how big and powerful the waves will be.

Click any table cell to jump to that forecast hour. The map will update with forecast arrows, so you can see if wind and swell direction are lining up.

Use the table sidebar to switch units for height and speed.

Models and Updates

Surfnerd blends multiple global and local wind and swell models using advanced interpolation and spatial techniques to create an "ensemble" forecast. Forecasts are refreshed hourly.

Surf Predictions

Our AI-driven algorithm scores surf quality, shown by green, orange, and gray dots. Each forecast hour is rated for wind, swell, and tide quality, then combined into an overall score. Hereโ€™s the scale:

Perfect
Good
Average
Bad or No Data

Session logs also feed the algorithm โ€” the more you log, the smarter your forecasts get.

With Surfnerd, no more "you should have been here yesterday"
