Waterfowlers talk about "the flight" like it's one event. It's actually a series of waves, each with its own timing and weather trigger. Here's how the Pacific Flyway moves through Washington.
Field briefing
Washington holds resident birds all season — mallards, wood ducks, Canada geese that never migrate far. The famous "flight birds" (northern pintail, widgeon, divers, lesser cans) push down with Arctic and interior cold snaps. Weather north of us matters more than the calendar.
Best for: waterfowl hunters planning vacation days and scouting trips. Key takeaway: hunt locals in October; watch northern forecasts for November waves; December is divers and weather gambles.
Season dates and limits vary by zone and year. Confirm current regulations before hunting.
Month by month
September–early October
Resident season. Local mallards, wood ducks, and teal dominate. Birds are patternable but educated around refuges. Best hunting is on quiet small water away from crowds.
Late October
First real pushes. Teal migration peaks early; pintail numbers build. First serious cold front usually drops a wave of fresh birds — watch forecasts for Alaska and Alberta lows.
November
Prime time. Northern birds mix with residents:
- Pintail and widgeon flood shallow estuaries and fields
- Scaup and other divers stack on big water — Lake Washington, the Sound's open bays, Columbia pools
- Field hunting for mallards improves with every storm
December–January
Weather-dependent glory or doldrums:
- Hard interior freezes push new birds continuously
- Deep cold concentrates birds on open water and after-front feeding sprees are legendary
- Extended freezes can lock shallow areas and scatter birds to saltwater and rivers
The weather triggers worth watching
- Northwest flow behind Alaska lows = classic push events
- Alberta clippers bring fast waves of fresh birds overnight
- Regional deep freeze locks prairie potholes and dumps everything south at once
Apps make this simple: check forecast maps for the Peace River country and Saskatchewan. Snow there means birds here within days.
Adjusting your setup by wave
| Bird wave | Where | Setup |
|---|---|---|
| Locals (Sept–Oct) | Small ponds, river sloughs | Small spread, hide well |
| First northerns (late Oct) | Shallow bays, fields | Bigger spread, more calling |
| Divers (Nov+) | Open water | Long-line rig, layout boats where legal |
| Freeze-up (Dec) | Rivers, salt edges | Follow open water |
Wrap-up
October for practice and locals, November for the main event, December for gamblers who watch northern radar. The birds will come — plan around their weather, not yours.
