Coastal Marsh Duck Migration Forecast

Where Coastal Marsh is

Coastal Marsh is drawn from 7 counties in Mississippi: George, Greene, Hancock, Harrison, Jackson, Pearl River and Stone. Those are the counties its shape on the DuckCast map is built from, so a hunter in any of them reads this region’s score.

When Coastal Marsh peaks

DuckCast’s season model puts the gadwall peak here around mid January. Coastal Marsh carries its own gadwall timing rather than the statewide curve, because the season here runs on a different clock from the rest of the state. That is a modelled typical curve, not a prediction for any single year. The actual push depends on cold fronts and freeze-up upstream, which is what the daily score tracks. Always confirm season dates with the state wildlife agency, linked below.

Which birds the model expects in Coastal Marsh

In DuckCast’s season model, the species that can score highest in Coastal Marsh are green-winged teal, snow geese and pintails. Against the state as a whole, it expects fewer mallards in Coastal Marsh.

Those weights come from harvest records, survey counts and the kind of water, not from a count taken here each season. They cap how high each species’ score can climb; the weather still has to bring the birds.

What DuckCast watches upstream of Coastal Marsh

2 upstream stations feed this region's freeze line, nearest first: Bolivar, TN, about 325 miles north and Paris, TN, about 400 miles north. When those stations ice over, the score here starts climbing before anything changes in the local sky.

Radar over Coastal Marsh

Each morning DuckCast reads the night’s NEXRAD data from KMOB, the National Weather Service radar at Mobile, about 35 miles east of the region’s weather point. That puts the radar just outside the region, near enough to see birds lifting off and passing close by. Radar sees every bird in the air, not only ducks, so it confirms or questions the score rather than moving it.

Locations stay generalized

Hunter reports for Coastal Marsh are always shown at the region level. DuckCast never collects or displays exact coordinates, so filing a report here never burns a spot.
