Most of the year is fishing. A few weeks of it are events.
Somewhere on every coast there’s a stretch of days when a ridiculous amount of fish and bait squeezes through a narrow place at about the same time every year, and the fishing stops looking anything like what you did in July. Locals take vacation for it. Everybody else hears about it the week after.
Nobody’s hiding the runs. What’s actually hard to find in one place is the order they happen in, and — way more useful — what sets each one off. The dates wander around from year to year. The triggers stay put.
Seasons · the run calendar
The order holds. The dates move every year.
- spring and summer
- the autumn events
- the shoulder
What actually starts a run.
Mostly four things, and the calendar is only ever a rough stand-in for them.
Water temperature crossing a threshold. Water, specifically, and the date barely counts. Most migrations follow a band of water temperature — striped bass moving north with the mid-fifties, tarpon showing up as the Gulf comes through the seventies. A cold spring holds everything back by weeks and a warm one runs it early, and the fish stay consistent about it even when the calendar doesn’t.
Day length. The only one of the four that doesn’t change from year to year. Spawning runs especially are cued partly by photoperiod (how long the days are), which is why some of them show up more on time than temperature alone would explain.
Bait leaving. The fall runs are mostly this. Mullet, peanut bunker, herring and anchovy pour out of the estuaries and down the beaches, and the predators are just following lunch. Watch the bait and you’re watching the run, several days before anybody posts about it.
Rain and river flow. For anything anadromous — salmon, steelhead, shad — a rise in the river is often the actual starting gun. Fish stage at the mouth waiting for water, and one good fall rain can move everything at once.
The regions, in the order their year unfolds.
Northeast and Mid-Atlantic
Striped bass push north in spring as the water comes through the fifties, then there’s a long summer, then the fall run — the event of the year, following cooling water and bait heading south. Bluefish overlap both. The fall run is worth rearranging your whole life around, and it doesn’t last.
Southeast and Florida
Cobia move along the beaches in spring with warming water. Then comes the mullet run in early fall, the single biggest beach event in the country, with snook, tarpon, jacks, kings and sharks all working the same moving bait within casting range of the sand.
The Gulf
Tarpon through the warm middle of the year, then bull redfish schooling up near the passes in fall. Winter pushes fish into rivers, canals and deeper holes, and cold snaps matter a lot more here than the mild averages make it sound.
West Coast
Surfperch through the cool months, when almost nothing else is happening on the beach. Then salmon in late summer and fall, staging off river mouths and running once the rain shows up — the flow matters more than the date by a wide margin.
Great Lakes and inland north
Walleye push into the rivers around ice-out, steelhead run in both spring and fall, and salmon stage and run up the tributaries in early fall. All of it keys on water temperature and river flow, and both of those swing a lot from year to year.
And the quiet months
Every region has them, and they’re the best time to learn a piece of water instead of chasing an event. The banks are empty, the parking lot is too, and you can walk a stretch at low water and see what’s actually under it.
How to know it’s on without waiting for somebody to post about it
By the time a run shows up on social media it’s often half over, and the crowd shows up with it. The signs that run a few days ahead of all that are free.
Bait first. Is there bait in the surf, in the inlet, off the pier, and which way is it moving? For the fall runs, nothing tips you off earlier or more reliably.
Birds, and specifically what kind. Terns working tight and diving means something is pushing bait up from below. Gulls sitting on the water usually means the bait’s there and nothing is chasing it.
A thermometer or a public buoy. Knowing your water crossed a threshold three days ago is basically the whole prediction, and coastal buoy data costs nothing.
River gauges, for anything anadromous. A rise after rain is the trigger, and the gauge readings are published.
Your own log from last year. Two seasons of honest notes on your own water beat every general calendar, this one included. Your notes are the only record that knows your latitude and your river.
The part worth planning around.
It’s fall. Almost every coast on that chart keeps its best week somewhere in it, and for the same reason: the bait is leaving as the water cools, and everything that eats is trying to get it done before winter.
If you only get a few trips a year and want them to count, stack them toward fall on whatever water you can reach, and spend the spring shoulder learning. That’s really a calendar decision, not a tackle one. Nobody sells a lure that fixes showing up two weeks late.
