Sealion Cove surf guide

Sealion Cove, also known as Shelikof Bay or Port Mary, is a laid-back surf spot that’s perfect for beginners. It features a sandy beachbreak, making it a good place to learn the basics of surfing without dealing with rocky or gnarly terrain. The spot offers a welcoming vibe and is often less crowded than other local beaches, which is great for those looking to practice their skills.

This spot works best with west swells, but you can also catch some action with southwest and northwest swells. It handles swell sizes starting from about 2ft to 6ft (0.6m to 1.8m). The waves break over sand, forming both lefts and rights, which gives you a chance to ride in either direction. You’ll want to keep an eye on the wind; easterly winds are preferable here. The tide can vary, but low, mid, and high tides all offer decent conditions to surf, making it a versatile spot for your sessions.

Sealion Cove is definitely suited for beginners, so if you're just starting out or looking for a chill place to improve your skills, you’re in the right spot. The combination of the sandy bottom, suitable swell directions, and forgiving wave types makes it a solid option for those new to surfing.

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.

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"
