K38/39 surf guide

K38/39, often referred to as "The Ks," is situated inside the breakwall of Point Judith Harbor of Refuge. It's known for being one of the longer left waves on the East Coast. The spot features two deep-water peaks that produce long, workable walls on the lefts and shorter, steeper rights at the more eastern take-off point of K39. While it can get some decent waves, the overall consistency is just average, so don't expect it to fire every session.

The best swell direction for K38/39 is from the south, with southeast and south swells also providing some options. This spot can handle swell sizes starting at around 3 feet (about 0.9 meters), breaking over boulders and creating both left and right waves. The lefts tend to be more favorable, but rights can also work, especially at K39. For the best conditions, low to mid tide is preferable, and you’ll want the wind coming from the north for the cleanest waves. It's a spot that suits beginners due to its generally mellow vibe, though there are no barrels here, even when it gets bigger.

Keep in mind that this area is busy due to it being the third-largest fishing port on the East Coast, which means you’ll find some motorized traffic, including jetskis, in the water. Since there’s no parking directly at the commercial port, your best bet is to park at the lighthouse and take a walk of nearly a mile along the breakwall. This can be a bit of a trek, so plan accordingly!

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"
