18th St. Jetty surf guide

18th St. Jetty is a surf spot located at the jetty in a popular beach area. It’s known for its easy access, although parking can get tricky during the summer months. If you’re heading out, make sure to bring some change for parking meters.

When the conditions are right, especially with a strong east-northeast swell, you can find decent lefts breaking off the groin. The wave size can range from around knee to head high (about 1 to 2.1 meters) and typically breaks over sand. The spot handles swell sizes from 3ft to 7ft (about 0.9 to 2.1 meters) and can work well with swell coming from various east and southeast directions. The preferred wind directions are west-southwest, west, and northwest. Keep in mind that the lefts can be a bit drifty when they’re working, and strong northeast winds can create challenging paddling conditions and current issues, usually moving north to south.

In terms of ability, this spot caters to beginners, intermediates, and even experts at times. Though it can get crowded, the currents may help spread out the surfers a bit. The local vibe tends to be mellow overall. Late summer, early fall, and early spring are the best times to hit this spot. Bring your shortboard, funboard, longboard, fish, or SUP, and enjoy the ride!

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"
