Avalanche surf guide

Avalanche is known for its heavy waves and challenging conditions, making it a spot that’s best suited for expert surfers. Located in an area that can handle significant swell sizes, Avalanche has a reputation for drawing in experienced locals and advanced paddlers. The atmosphere can vibe a bit competitive at times, especially on the bigger days when the line-up can get busy with familiar faces.

The waves at Avalanche really come to life with a north-west swell, typically breaking over an uneven reef. It’s a left-hand wave that can handle swells around 10ft (about 3 meters) or bigger, offering some long, muscular shoulders. The best time to hit the water is usually on low tide, which can produce some solid, meaty walls. For those heading out, a south-east wind is preferred, making it a bit easier to catch those clean sets.

If you’re heading out to Avalanche, be prepared with the right equipment—a thicker, longer board is a must for paddling into those big waves. Keep in mind that while small to medium days can sometimes bring in a crowd, it’s generally the hardcore surfers who know the spot well. Make sure you have the skills to match the conditions, as it’s definitely not a place for the faint-hearted.

Welcome! If you’re new to surf forecasting, check out this quick guide.

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.

Log your surf sessions to compare forecasts with real sessions and sharpen future predictions.

On the map, click a metric label to bring that arrow to the front — handy when arrows overlap.

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.

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

Wind certainty

Wind certainty tells you how much the weather models agree on the forecast.

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

We calculate this by comparing wind speed, gust and direction from multiple models (like GFS, ECMWF, Arome, and Harmonie) and seeing how closely they match. They are weighted, meaning that some models count more than others, depending on how good they are for a certain spot.
