Winchester Bay/South Umpqua Jetty Surf Forecast Guide

Winchester Bay/South Umpqua Jetty is a man-made righthander on the south side of the mighty Umpqua River entrance, where an Army Corps rock jetty reaches about 1000 yds (910m) into the Pacific. The jetty doubles as a wind block and lets sand pile up into bars, feeding a reliable, sometimes dredging right that peels away from the rocks in often classic form. It breaks over sand, and a rip usually runs along the jetty to give you an easy paddle back to the lineup. On most S to NW swells a nice left peak sets up about 100 yds (90m) to the south, and when it's glassy there's a near-infinite stretch of peaks down the dunes of the Siuslaw National Forest.

When It Works

The spot draws swell from south through west-southwest to northwest (S-WSW-NW), with northwest (NW) the best match, and it really comes alive on NW and W swell as one of Oregon's good big-wave spots. Although the sandbars shift, it handles a significantly larger swell than most, if not all, of the state's outside jetty breaks. It works from 0.6 m / 2 ft to 4.6 m / 15 ft and tends to be moderately consistent.

Wind and Tide

The offshore wind direction is east (E), and it works across low, mid, and high tide, with a rising tide generally the better call. Keep in mind the spot is exposed to S winds, and since most big winter swells arrive with S winds, genuinely good conditions are rare.

Local Tips

This righthander suits intermediate surfers, and you can expect a moderately busy lineup when it's on. You might run into the odd unfriendly local, so grin and bear it, and be aware of a relatively major shark hazard here.

Access

The beach is public, with a car park offering free parking plus roadside parking. Since the spot is visible from Highway 101, you can scope it first from the overlook at the top of the hill just south of Winchester Bay.

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.

๐ŸŽฏ Model agreement

The small letter in the wind and wave cells shows how closely the weather models we blend agree for that hour.

  • H, the models line up closely.
  • M, the models differ somewhat, so conditions may still shift.
  • L, the models disagree, so check again closer to your session.
  • A dash means only one model covered this hour, so there was nothing to compare.

For wind we compare each model's wind vector, plus gusts where every model reports them. For waves we compare height, period and direction of the matched swell systems.

It is a measure of model agreement, not a probability that the forecast is right.

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.
