Nosara Surf Forecast Guide

Nosara is a sand-bottomed beachbreak on the Guanacaste Coast of Costa Rica's Nicoya Peninsula, throwing both rights and lefts along a long stretch of open beach. The town carries the name, but the surf itself happens at Playa Guiones, where a couple of miles of coast give you several peaks to pick from. Some sections break over rock and take on a canyon-like shape, and the whole setup rates as reliably fun with days that turn out quite good.

When It Works

Swell arrives from south to southwest, and the beach works from 1.5 m / 5 ft to 2.1 m / 7 ft. Spring and summer are the seasons to target, with March through August the meat of it. The wider region is drier than much of Costa Rica thanks to the Papagayo winds that blow half the year, and south-facing beachbreaks like this one will pick up the smaller swells that pass other spots by.

Wind and Tide

Look for east-northeast offshore wind, though anything in the northeast to east window is workable. Guiones can break through low, mid, and high tide, so you have room to move your session around, but a rising tide is generally the better call and mid tide on the push is the classic window here. When the swell gets big, the points and reefbreaks nearby come into their own at lower tides.

Local Tips

Expect a busy lineup. The peaks spread out over two miles of beach, but the most consistent ones can stack up with twenty surfers waiting on the same wave, especially through summer when visiting surfers show up in numbers. The lineup can feel a little reserved, so read the room before you paddle for everything. Board choice is wide open: shortboards, fish, funboards, longboards, and bodyboards all have a place, and there's something here for beginners through to experts. The paddle out is medium effort. The water is clean, and the main thing to watch is simple: don't turn your back on the ocean.

Access

At the end of the road you'll find an informal lot, and plenty of people just pull over on the roadside instead. The first 50 meters back from the sand have been left undeveloped to protect the coastline, so the walk in stays short and the beach stays open.

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.

๐ŸŽฏ Model agreement

The small letter in the wind and wave cells shows how closely the weather models we blend agree for that hour.

  • H, the models line up closely.
  • M, the models differ somewhat, so conditions may still shift.
  • L, the models disagree, so check again closer to your session.
  • A dash means only one model covered this hour, so there was nothing to compare.

For wind we compare each model's wind vector, plus gusts where every model reports them. For waves we compare height, period and direction of the matched swell systems.

It is a measure of model agreement, not a probability that the forecast is right.

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"
