Timeline

Florence - South Jetty Surf Forecast Guide

Overview

Florence - South Jetty sits at the Siuslaw River mouth, between massive rock jetties on a sand bottom. The South Jetty angles south, making a sheltered nook for lefts and rights just outside Florence.

When It Works

The spot is consistent and works from 0.6 m / 2 ft to 3 m / 10 ft. It takes swell from south through west-southwest to northwest, with southwest the optimal swell direction.

On small north-wind summer days, it can pick up south and southwest swell in the sheltered nook. On big west swells at lower tides, a left can peel between the jetties off the south jetty, around a third the size of the outside swell.

Wind and Tide

The offshore wind direction is northeast. Low, mid, and high tides can all be in play, with a rising tide better.

Be careful between the jetties. A lot of water drains through here, and an outgoing tide can sweep you from the break out past the bar. Check the tide charts.

Local Tips

Best suited to intermediate surfers. It can get busy, and the local scene may not feel especially welcoming.

There are moderate shark concerns here.

Access

Cross the river to Glenada and turn into the Oregon Dunes National Recreation Area. Follow the narrow blacktop for about 5 mi / 8 km; when the road turns into a moonscape of giant potholes, youโ€™re close. Walk out on the jetty and check both sides.

Thereโ€™s a car park with free parking, plus restrooms, showers, camping, a lifeguard, and a surf shop.

Readme

Welcome! If youโ€™re new to surf forecasting, check out this quick guide.

Forecast Table

The forecast table (the section on the page with all the numbers) is designed to pack as much information in the screen as possible. Although intimidating at first, it will help you make informed decisions about the waves faster, trust me :D. The table consists of roughly four sections, time and predictions, wind, waves, and tides:

๐Ÿ”ฎ Time and predictions section

Here we show the forecast thour and the overall surf quality prediction. This is determined based on the wave, wind and tide quality prediction. These individual predictions can be found on the forecast map.

๐Ÿ’จ Wind section

The first row on the table (with the ๐Ÿ’จ icon) shows wind speed, direction and gust. The more the wind speed the more aggressive the color (from blue, green, orange to red).

๐ŸŒŠ Wave section

The waves section consists of three rows, one for wave height and direction, one for period and one for wave energy. Our algorithm chooses the "dominant wave" using spot-adjusted surf energy (depth + directional fit). This is usually the first swell partition, but during local storms it can switch to wind waves. If that happens, values are shown in gray and italic.

๐ŸŒ’ Tide section

The tide section consists of a row with the actual heights per hour (measured at the half hour) and a table that displays the flow of the tide and the extremes (lows and highs).

Forecast map

The forecast map consists of arrows. These arrows represent all wave partitions (swell partitions and wind wave partition) and the wind. This allows you to see things like: a secondary swell or wind waves messes up the surf, or the wind is just a tick offshore so very surfable. Click a metric label in the bottom left to bring that arrow to the front โ€” handy when arrows overlap.

Forecast Cheat Sheet

Short on time? Focus on wave energy. Itโ€™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.

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. Hereโ€™s the scale:

Perfect
Good
Average
Bad or No Data

Session logs also feed the algorithm โ€” the more you log, the smarter your forecasts get.

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

Confidence

Confidence tells you how much the weather models agree on the forecast.

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

We calculate the wind confidence by comparing wind speed, gust and direction from multiple models (like GFS, ECMWF, Arome, and Harmonie) and seeing how closely they match. For wave certainty we compare height, period and direction, also on multiple models. They are weighted, meaning that some models count more than others, depending on how good they are for a certain spot.
