Shark Pit - Marin surf guide

Shark Pit is located way offshore at the mouth of Tomales Bay in Marin. It's known for its powerful left-hand waves that can deliver epic barrels. The spot works best with W-NW swells and SE-E winds, but you need to time it right as conditions can vary quite a bit. The distance from shore means that getting to the breaks might require a boat, especially since the area is famous for its resident great whites. This spot is one of the best left-hand waves in Northern California, but it doesn't happen often, so be prepared for some waiting around.

The surf really starts to kick in when the swell hits around 6 feet (about 1.8 meters). It can go all the way up to triple that size under the right conditions. The waves break over sand and can be pretty consistent with a nice left peel, especially on incoming tides. The ideal swell direction is Northwest, but it can also handle swells coming from the West, making it versatile for onlookers. However, you should be an expert if you decide to paddle out here, as the powerful current and occasional big sets are not for beginners.

When you’re planning a trip, keep in mind that the best time to surf is during low, mid, or high tide, depending on the swell and wind conditions. The preferred wind direction is Southeast for optimal conditions. Just be aware that this area is a breeding ground for great whites, so it's crucial to keep your wits about you. Enjoy the ride, but remember to stay safe out there.

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.

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"
