The Boom Surf Forecast Guide

The Boom is a well-known surf spot located in Northern Nicaragua, famous for its consistent beachbreaks and stellar barrel rides. Pioneered by Shay O’Brien and his family when they founded Chancletas Beach Resort, it has become a popular destination for surfers looking to catch some serious waves. The area is characterized by its beautiful sandy beaches and a fun, relaxed vibe, making it a great spot to hang out and surf.

When it comes to surfing, The Boom is definitely a mixed-bag experience. The waves generally handle swells from 3 to 8 feet (about 1 to 2.5 meters), with the sweet spot being during mid to high tides. It works best with swells coming from the south and south-southwest, and ideally, you want the wind blowing from the northeast or east-northeast. The sandy bottom helps keep things smooth, but don't be fooled; while the waves don’t usually get much taller than a couple of feet overhead, they can pack a punch and catch you off guard. This spot is suitable for intermediate to expert surfers, and it's famous for giving regular folks some epic rides. The two main areas to surf are Coconuts to the north and Powder Puffs to the south, while The Boom proper is located right in the middle.

Getting to The Boom is easy since you can drive right onto the beach with your 4x4 or motorcycle. However, staying at Chancletas and taking a short stroll down the path is usually the way to go. The crowd factor can vary a lot—timing is key to avoid sharing a peak with too many surfers. Just be aware that it can get particularly hot here, so staying hydrated is essential. In terms of boards, shortboards are definitely the way to go for navigating these waves. Overall, The Boom delivers a mix of fun and challenge, making it a solid choice for surfers looking to maximize their time in 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 you’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:

🔮 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.

💨 Wind section

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

🌊 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.

🌒 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 — handy when arrows overlap.

Forecast Cheat Sheet

Short on time? Focus on wave energy. It’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. Here’s the scale:

Perfect
Good
Average
Bad or No Data

Session logs also feed the algorithm — the more you log, the smarter your forecasts get.
