January is Oklahoma's deep-winter month, when bald eagles gather below the dams and great prairie flocks of geese and longspurs work the bare fields. The leafless Cross Timbers and open mixedgrass plains lay every silhouette bare under short, often windy days.
Week by week in January
January 1–7
- Bald eagles gather below the dams at Lake Texoma and Sequoyah NWR and on the open big lakes, perched in the bare cottonwoods.
- The Quadrantid meteor shower peaks around January 3 in a short, sharp burst; look northeast after midnight from a dark western-Oklahoma sky.
- The Cross Timbers post oaks and blackjack oaks hang onto their leathery brown leaves, giving the winter timber its shaggy look.
- A planning and pruning month; order seed early and prune dormant fruit trees and grapes on the rare calm, mild day.
January 8–14
- Vast flocks of snow, Ross's, and greater white-fronted geese blanket the fields and refuge at Salt Plains and Hackberry Flat.
- Sweet potatoes, winter squash, and frost-sweetened root crops carry the lean winter markets, with high-tunnel greens and fresh pecans.
- Orion stands high in the south after dark; trace his belt down to brilliant Sirius, the brightest star in the night sky.
- Feeders fill with Harris's, white-throated, and white-crowned sparrows and dark-eyed juncos, the Great Plains winter crowd.
January 15–21
- Northern harriers course low over the prairie and stubble holds Lapland longspurs and horned larks across the open western counties.
- The Pleiades cluster and orange Aldebaran ride high overhead in the early evening above the dark Wichita Mountains.
- Dark eastern red cedars stand out on fencerows and old fields, their blue cones feeding wintering waxwings and bluebirds.
- Start onion and leek seeds indoors under lights now, the slowest transplants to get a head start on the Oklahoma spring.
January 22–28
- Cedar waxwing and American robin flocks strip cedar and holly berries, while Western meadowlarks whistle on milder days.
- Native witch-hazel may open thin yellow petal-ribbons in sheltered eastern Oklahoma hollows, the lone winter bloomer.
- The dark Black Mesa country in the far panhandle offers superb cold, clear winter stargazing far from any city glow.
- Plant bare-root fruit trees, blackberries, and roses while dormant, and tuck in onion sets late in the milder south.
Birds This Month
January is the best bald eagle month in Oklahoma. Eagles concentrate below the big Corps dams and on the open water of the great lakes — Sequoyah NWR and Robert S. Kerr on the Arkansas River, the tailwaters of Lake Texoma, Keystone, Kaw, and the Salt Plains reservoir all reliably hold wintering birds in the bare cottonwoods and sycamores, and several refuges and state parks run eagle-watch events this month.
The open country is full of hardy winter specialties unique to the plains. Vast flocks of snow geese, greater white-fronted geese, and Ross's geese blanket the fields and refuge marshes at Salt Plains, Hackberry Flat, and Sequoyah, while pastures and stubble hold flocks of Lapland longspurs, horned larks, and the year-round Western meadowlark, whose whistled song carries even on cold days. Watch fence wires and brush for wintering Northern harriers coursing low, red-tailed hawks, and the occasional prairie falcon or rough-legged hawk down from the north, and scan western shelterbelts for irrupting red-breasted nuthatches.
The feeder yard from Tulsa to Lawton fills with Northern cardinals, dark-eyed juncos, Harris's sparrows — a Great Plains winter signature — white-throated and white-crowned sparrows, and Carolina chickadees, while cedar waxwings and American robins strip cedar and holly berries.
This month's tip: go to a dam tailwater at first light for eagles, then drive the refuge auto routes at Salt Plains or Hackberry Flat for geese and raptors. Dress for biting wind off the open prairie, which makes January feel far colder than the thermometer reads.
What's Blooming
January is the quietest wildflower month across Oklahoma, with the tallgrass and mixedgrass prairies brown and dormant and the Cross Timbers floor under leaf litter. True flowers are scarce, though in the milder south a stray henbit or common chickweed may open on a warm afternoon, and the green basal rosettes of next year's prairie plants already wait in the sod.
The reward now is structure rather than color. On a remnant like the Tallgrass Prairie Preserve, the cured stems of big bluestem, little bluestem, and Indian grass glow copper and wine-red in the low winter light, and the blackened seed heads of purple coneflower, compass plant, and Maximilian sunflower stand stiff above the snow, feeding goldfinches, juncos, and sparrows.
Where to see it: walk a prairie remnant or a Cross Timbers glade and read the dried architecture — knowing which species stand where now tells you exactly where May's Indian blanket and coreopsis will explode. In sheltered eastern hollows, look for the thin yellow petal-ribbons of native witch-hazel, the one true cold-weather bloomer of Oklahoma's eastern woods, opening on mild days.
Garden This Month
January is Oklahoma's pruning and planning month, and the relatively mild south-central climate lets you accomplish real work outdoors between cold snaps. With trees and vines dormant, this is the prime window to prune apples, pears, peaches, blackberries, and grapes — the bare branch structure reads clearly and the plants will not bleed in the cold. It is also the best time to plant bare-root and dormant stock: fruit trees, berry canes, roses, and shade trees settle in best when set into cool soil now, ahead of Oklahoma's quick, hot spring.
The rest of the month is preparation. Order seed before the popular tomato and pepper varieties sell out, and start the slowest transplants — onions, leeks, and early cabbage and broccoli — indoors under lights. Across central and southern Oklahoma, hardy spinach, kale, and collards can overwinter under row cover, and you can tuck in onion sets late in the month if the ground is workable. Keep mulch heaped over garlic, strawberries, and perennial crowns, because Oklahoma's wild freeze-thaw swings and drying winter wind heave shallow roots right out of the soil. Resist setting out anything tender — the average last frost is still well over two months away statewide, and a January warm spell is never the real spring.
Zone 6b (the panhandle and far northwest): Oklahoma's coldest, windiest corner is fully dormant, with hard freezes and biting High Plains wind the rule. Keep heavy mulch over garlic, strawberries, and perennial crowns against brutal freeze-thaw heave, protect any covered greens with row fabric or low tunnels, and use the month to plan, order seed, and prune dormant fruit trees on the rare still, mild day.
Zone 7a (central and northeastern Oklahoma, Tulsa and Oklahoma City): still firmly dormant, but the days are lengthening. Prune dormant apple, pear, and grape now while the structure is bare, plant bare-root fruit trees, blackberries, and roses, and start onion and leek seeds indoors under lights for an early-spring transplant.
What's at the Farmers Market
January is the lean season at Oklahoma markets, kept alive by the indoor and year-round venues and the winter high-tunnel growers. The big-three winter markets carry it: the climate-controlled OSU-OKC Farmers Market in Oklahoma City, the year-round Cherry Street Farmers Market in Tulsa, and Norman's Cleveland County Fairgrounds winter market, with the Edmond and Stillwater markets running reduced winter dates. The defining Oklahoma product on the table now is the pecan — the state is a top native-pecan producer, and freshly cracked native pecans from the bottomland groves of the Canadian, Red, and Washita river valleys around Okmulgee, Chickasha, and the Caddo and Kiowa country fill the pantry stands.
Alongside the pecans, look for cured 'Beauregard' and 'Orleans' sweet potatoes from the sandy fields of the Arkansas River bottoms near Porter and Bixby, storage butternut and 'Honeynut' squash, and high-tunnel greens the cold actually sweetens — 'Winterbor' kale, collards, mustard, tatsoi, and 'Space' spinach. Stored 'Candy' and '1015Y' onions and Oklahoma-grown garlic round out the roots, beside jars of mesquite and clover honey and dark sorghum syrup from Coal and Atoka county presses.
This is also the month to plan ahead with the growers themselves. The Porter peach orchards of the Arkansas River Valley — home of Oklahoma's oldest fruit festival — sit dormant now, as do the Bixby tomato fields and the strawberry rows of Stilwell in the Cherokee hills, so a January market table is the place to ask which heirloom varieties a farm will bring and to reserve an early-summer CSA share before spring fills it up.
Night Sky This Month
Oklahoma's darkest skies are out west, far from the Tulsa and Oklahoma City glow. The remote Black Mesa country in the far panhandle — the state's highest ground at nearly 4,975 feet — offers some of the blackest skies in the southern Great Plains, and Black Mesa State Park and nearby Lake Carl Etling host occasional star parties. The granite-walled Wichita Mountains near Lawton and the broad horizons of the western mixedgrass prairie also open up huge, dark skies, and January's long nights bring full dark by early evening.
Overhead, the brilliant winter constellations ride high. Orion dominates the south, his three-star belt pointing down to Sirius, the brightest star in the night sky, and up to the Pleiades cluster and orange Aldebaran in Taurus. Reddish Betelgeuse and blue-white Rigel mark Orion's shoulder and knee, and the faint winter Milky Way arches overhead on a clear, dry prairie night.
The year's first meteor shower, the Quadrantids, peaks in the first days of January, typically around January 3, in a sharp, narrow window radiating from below the Big Dipper's handle, best after midnight from a dark, moonless site. Because the exact Quadrantid peak and the planets' positions shift each year, check the printable Oklahoma night-sky guide for this year's specific viewing nights and planet visibility from your latitude.
Butterflies & Pollinators
January pauses Oklahoma's butterfly season, but the state's winter is mild enough that a handful of adults overwinter in hiding rather than dying back entirely. In the eastern oak-hickory woods and the sheltered Cross Timbers canyons, the mourning cloak and the question mark tuck behind loose post-oak bark, in woodpiles, and in rock crevices, and on a sunny January afternoon in the warmer south one may flush from a brush pile, dark and ragged, before vanishing again.
In the milder south-central counties an exceptionally warm spell can also rouse a goatweed leafwing from the leaf litter or a sleepy orange from a sheltered field edge — the leafwing's dead-leaf underside is perfect winter camouflage in the Cross Timbers. The dry western panhandle, colder and windier, offers almost nothing on the wing. The monarchs that streamed south across the Oklahoma prairies in October are now clustered far away in the Mexican mountain forests.
To prepare for the season ahead: January is the month to plan the butterfly garden, not to watch it. Map beds of native milkweed for monarchs, native passionflower for fritillaries, and prairie nectar like Indian blanket and coreopsis, and leave brush piles and leaf litter standing so the overwintering adults have shelter.

Trees This Month
January reveals the bones of Oklahoma's trees and the sharp contrast between its regions. In the eastern oak-hickory hills and the Cross Timbers, the gnarled, low-branched post oak and blackjack oak hold many of their leathery dead leaves through the winter, giving the rough timber its characteristic shaggy brown look, while bottomland sycamores glow with white, flaking upper bark and cottonwoods stand bare and massive along the prairie rivers.
The green in a January Oklahoma landscape is almost all eastern red cedar, the aggressive native juniper that has spread across overgrazed pastures, glades, and fencerows statewide; its dense dark foliage and blue berry-like cones feed wintering cedar waxwings and bluebirds and shelter roosting birds. In the southeast, planted and native shortleaf pine and loblolly pine hold the Ouachita foothills dark green, and bald cypress stands leafless and gray over the lake edges and swamps. The state tree, the eastern redbud, waits as a small understory tree, its flower buds already set along the branches for a magenta March.
