What to look for in nature in Missouri this October

The Missouri Department of Conservation says peak color “is usually around mid-October,” that it “usually starts earliest in northern and western Missouri and moves southward and eastward across the state,” and that its weekly reports run from the second half of September to about the middle of November. The order of the trees is more reliable than the calendar: sassafras, sumac and Virginia creeper first, then black gum, bittersweet and dogwood, and the big show of maples, ashes, hickories and oaks last. White oaks, in a good year, turn claret red in the second half of October across most of the state, and shagbark hickories go a rich golden yellow. At the far southeastern end, Mingo National Wildlife Refuge puts its peak in the last week of October, with the bald cypress already turning in September.

The 2026 caveat is dry ground. On September 22 the U.S. Drought Monitor had 62 percent of Missouri abnormally dry or worse, a third in moderate drought, 22 percent in severe drought and 11 percent in extreme drought, and MDC’s September 24 report described stressed trees browning and dropping leaves early in the Ozarks and the southwest, where “a short, muted fall color season” is expected. Drought does not cancel color; it shortens it. Check the MDC fall color report each week and go the week your region turns. For your own woods, drop a pin in the Field almanac and it will show when satellites usually see the leaves turn there.

Loess Bluffs National Wildlife Refuge, formerly Squaw Creek, is 7,440 acres of wetland under the loess hills near Mound City in the far northwest, and October is when it fills. American white pelicans are the September bird: MDC puts the statewide fall peak in mid-to-late September, with the last birds gone by mid-November, and October is their long tail. Snow geese “begin to arrive at the refuge in mid-October with the peak in mid to late November,” and the fall-and-winter total runs to “upwards of a million,” with up to 200,000 ducks alongside. Bald eagles follow the geese: as many as 300 by about the first of December, and a record of more than 660 in a 2020 survey. The 10-mile auto tour opens half an hour before sunrise and closes half an hour after sunset. Go at first light or last light, when the flocks trade between the pools and the fields.

Elsewhere the pelicans use the big western reservoirs and the Missouri River, and MDC is candid that the eastern half of the state sees far fewer. Trumpeter swans are not an October bird here; MDC says they are typically present from late November until late March. Swan Lake’s wildlife drive closes for the season at the end of the month, so that one is now or March.

Monarchs, honestly: Missouri’s peak is a September event. Monarch Watch’s recovery data put the twelve-day peak at latitude 39° N (Kansas City, Columbia, St. Louis) at September 14–26 and at 37° N (Springfield, Joplin) at September 19 to October 1, so October is the tail of the migration, thickest in the first week and in the south, with stragglers into mid-month. They are still worth reporting: Journey North wants fall roosts especially, gatherings in trees at night, whether “of 10 monarchs or 1,000,” and Monarch Watch pays about $5 for each tag recovered in Mexico.

eBird’s global October Big Day is Saturday, October 10, and a list from the yard counts. Project FeederWatch begins on November 1.

It depends on which side of the Missouri River you live on, and on how much pavement is around you. In the far north the first freeze is an early-October risk: at St. Joseph one year in ten has already frozen by September 30 and at Kirksville by October 2, with medians in the third week of October. Kansas City’s median is October 24, Springfield’s October 27 and Columbia’s October 31, while the St. Louis station, downtown at the Science Center, holds out to November 4 on the strength of the city’s heat. Joplin and Cape Girardeau run within a day or two of Kansas City. The month’s normals tell the same story: an October normal high of 67–71 °F and a normal low of 43–49 °F, with September’s 80s behind and November’s 50s ahead.

Look up the station nearest you on our first and last frost dates for Missouri, which covers hundreds of towns. North of the river, pot up the geraniums and pick the last peppers early in the month, and note the night of the first frost; south of it, the tomatoes usually get a few more weeks. Persimmons do not wait for the frost, whatever the old rule says: MDC dates the fruit September–October, and the tree decides.

Between 67 and 75 minutes, depending on latitude. That is about two and a half minutes a day at Kirksville and two and a quarter at Cape Girardeau. Kansas City’s sunrise slips from 7:14 to 7:45 a.m. across the month and its sunset from 7:01 to 6:18 p.m.; St. Louis goes from 6:57 and 6:43 to 7:27 and 6:02. Evening civil twilight in Kansas City ends at 7:27 p.m. on October 1 and 6:46 p.m. on Halloween. Standard time returns early on Sunday, November 1, when 2:00 a.m. becomes 1:00 a.m., and the evening commute goes dark.

To see how fast your own evenings are shrinking, open the Field almanac: it lists sunrise, sunset and twilight for any Missouri address along with this week’s loss in minutes.

October is a middling month for rain here and, by Missouri standards, a kind one. The 1991–2020 normals run from 2.8 inches at St. Joseph to 3.8 at Joplin, with Kansas City at 3.3, St. Louis 3.2, Columbia 3.5, Springfield 3.6 and Cape Girardeau 3.6. September is wetter than October at every one of those stations except Cape Girardeau, where November is the wetter neighbor.

This year starts dry: the drought figures in the fall color section above mean low rivers and a short color season.

The bigger question is winter, and the answer runs through the Pacific. The Climate Prediction Center’s September 10 discussion put the odds of a very strong El Niño this fall and winter above 90 percent, and gave a 75 percent chance that it tops every El Niño in the record back to 1950. For Missouri the signal is mixed. In CPC’s September 17 outlook the reliable wet signal runs from the southern Plains to the Gulf and Southeast coasts, the Great Lakes lean slightly dry, and warmer-than-normal odds cover the northern and central states east of the Rockies. Missouri sits between the wet south and the dry lean to the northeast, inside the warm-leaning area. We found no Missouri-specific outlook yet, so read this as a tilt, not a forecast: if the usual pattern holds, a milder winter than normal, with any wet tendency more likely toward the Bootheel than the north. No two events are alike; as climate.gov puts it, “associated with” does not mean it happens every time. CPC’s next ENSO discussion is due October 8, and NOAA issues its winter outlook on October 15, after which we will explain what it says for Missouri.

Before you set an alarm, check the cloud forecast for your part of Missouri; our Moon phase calendar has local moonrise and moonset times.

Yes, and October is the quiet, clear-water month, but it is a low-water month too, and this year more so. The Forest Service says of the Eleven Point, a 44-mile Wild and Scenic river fed by Greer Spring, that “July through October is generally the low flow period and canoeing may not be possible” from the top access at Thomasville, so put in lower, where the springs have added their share. On the Current and Jacks Fork the Park Service closes the rivers to paddlers at two feet above normal, which is not October’s problem; the fall question is whether there is enough water above Akers or above Alley Spring to float without walking. Read the USGS gauges before you drive; the Park Service’s river-levels page links the ones at Montauk, Akers and Van Buren on the Current and Mountain View, Alley Spring and Eminence on the Jacks Fork. One life jacket per person on board, children under seven wearing theirs, no glass, no lashing boats together.

The trout parks close catch-and-keep on Saturday, October 31. Bennett Spring, Montauk, Roaring River and Maramec Spring are stocked daily until then, with a $5 daily tag ($3 for age 15 and under) and a four-fish limit; the flies-only winter catch-and-release season opens Friday, November 13. If you visit the Big Muddy refuge units along the lower Missouri, watch the river stage and stay away when it reaches action flood stage or higher.

1. Saturday, October 3: Evening on the Prairie. The Missouri Prairie Foundation’s annual gathering at Friendly Prairie near Ionia, 2 to 9 p.m., with guided prairie walks and room to pitch a tent, free with registration (dinner is extra).
2. Saturday, October 10: the Missouri Chestnut Festival at MU’s research farm in New Franklin, 10 a.m. to 3 p.m., free: chestnuts cooked several ways, pawpaw ice cream, hay wagon rides through the orchards, a kids’ zone. The same day is eBird’s October Big Day; count the yard.
3. Drive the Loess Bluffs auto tour from mid-October for the first snow geese.
4. Drive Peck Ranch for elk at first or last light, any day but October 11–12.
5. Saturday, October 17: a foraging walk at Powell Gardens near Kingsville, 3 to 5 p.m.; the gardens are open Wednesday to Sunday, 9 to 5, through November 1.
6. October 28–29: Katy Trail Fall Colors tram tours from the Rocheport trailhead to McBaine, 10 a.m. to noon and 1:30 to 3:30 p.m., a suggested $5 donation, preregistration required through the park office.
7. Find a monarch roost? Send it to Journey North that same night; families with a Monarch Watch tagging kit can tag the stragglers. Join Project FeederWatch before it starts on November 1.
8. Set the alarm for Jupiter behind the Moon on October 6, or for the Orionids on the mornings of October 21 and 22.

MDC’s nature centers in Kansas City, St. Louis, Jefferson City, Springfield and Cape Girardeau usually run free programs in the fall, but their October calendar was not posted when we checked, so call or look online before you go.

• Deer on the roads: the rut peaks in mid-November and the run-up is now. MDC’s advice is to “be careful when driving at night, at dusk, and at dawn.”
• Ticks: “most active April–July, but they may be encountered nearly any time of year.” Check yourself after every walk.
• Snakes: copperheads until they den in mid-to-late October, rattlesnakes to mid-month. Watch hands and feet.
• Hunting seasons this month: archery deer and turkey all month; fall firearms turkey October 1–31; early antlerless firearms deer October 9–11 in select counties; black bear October 17–30 in the southern half; elk archery October 17–25; early youth firearms deer October 24–25; youth waterfowl October 24–25 (North Zone) and October 31 – November 1 (Middle Zone); North Zone ducks from October 31; the November firearms deer portion opens November 14. The hunter-orange rule binds anyone hunting any game during a firearms deer portion, including the October 9–11 and 24–25 weekends, and all black bear hunters, with a few exemptions (mainly migratory-bird hunters and some archery hunters): “You must wear both a hunter-orange hat and a hunter-orange shirt, vest, or coat. The hunter-orange color must be plainly visible from all sides. Camouflage orange does not satisfy this rule.” It does not bind hikers, but MDC urges orange “whenever you are hunting,” and our advice for anyone on public land those weekends and from November 14 is an orange hat and vest.
• Managed hunts close areas on short notice: Peck Ranch’s driving tour on October 11–12, and waterfowl closures on parts of Eagle Bluffs from October 15. Check the area page before you drive.
• Rivers: low and clear; a life jacket aboard for everyone, worn by children under seven.
• Drought: much of the state is in drought and the leaves are coming down dry; check local burn bans before a campfire.
