Wisconsin Nature Guide: February 2026
Data updated: August 2026Sources & method · Corrections
February is the coldest, snowiest stretch of the Wisconsin year, but the light is visibly returning and the first faint signals of spring stir beneath the deep freeze. The marshes stay locked in ice, yet on mild mornings chickadees begin to whistle and great horned owls are already on eggs in the bare woods.
Week by week in February
January 29 – February 4
- Great horned owls are already on eggs in the bare woods, their deep hooting carrying far on still, cold nights across the state.
- Set up the grow-light shelf and start the slowest seeds — onions, leeks, and celery — for transplants you'll set out in late May.
- Orion stands due south in the evening, with the hazy glow of the Great Nebula in his sword visible in binoculars from a dark site.
February 5–11
- Bald eagles crowd the open water below the Wisconsin River dams near Sauk City and Prairie du Sac, one of the state's great winter wildlife sights.
- February's long, cold, crystalline nights offer the finest stargazing of the year, with the brilliant Winter Hexagon riding high overhead.
- Within the sugar maples, sap is beginning to stir as the daily freeze-thaw cycle starts — the engine of the syrup season just ahead.
February 12–18
- On milder mornings, chickadees whistle their spring song and cardinals start their 'cheer-cheer-cheer' from the treetops — the first audible turn of the season.
- Start tomatoes' slower companions now under lights, and finish dormant pruning of apples and oaks on a thaw day before the sap rises.
- The catkins of hazelnut and alder lengthen and loosen on warm days, the earliest stirring of the coming pollen season.
February 19–25
- The first jugs of fresh maple syrup appear late this month as warm days and freezing nights start the sap running in the southern sugarbushes.
- Barred owls begin their courtship 'who-cooks-for-you' calls, while snowy owls still hunt open country and the icy harbors up north.
- Leo the Lion rises in the east late in the evening, a herald of spring, while the Big Dipper swings high in the northeast.
Birds This Month
Feeders stay busy through February's cold — black-capped chickadees, nuthatches, cardinals, and woodpeckers are joined by American tree sparrows and any lingering irruptive redpolls and pine siskins. The first real sign of the turning season is in the chickadee's whistle: on milder mornings they begin singing the clear two-note fee-bee spring song, and cardinals start their cheer-cheer-cheer from the treetops.
This is also peak owl month. Great horned owls are already incubating eggs in the bare woods, their deep hooting carrying far on still, cold nights, and the early-courting pairs of barred owls answer with their who-cooks-for-you calls. Up north, snowy owls still hunt open fields and the icy harbors, and bald eagles crowd the open water below dams on the Wisconsin River, gathering thickly near Sauk City and Prairie du Sac.
This month's tip: keep the heated water and high-fat suet going — late February cold snaps are hard on birds whose energy reserves are running low after a long winter.
What's Blooming
February is still firmly winter in Wisconsin, with no wildflowers blooming and the ground frozen statewide. The landscape's color comes from bark and berry: the crimson stems of red-osier dogwood, the lingering fruit of winterberry and highbush cranberry, and the catkins of hazelnut and alder beginning to lengthen and loosen on warmer days — the earliest stirring of the coming pollen season. Indoors, this is the heart of seed-starting and houseplant season; the strengthening February sun pulls geraniums and overwintered herbs back toward growth on a bright sill. Outdoors, look closely at the swelling buds on silver maple and willow, the trees that will flower first when the thaw finally comes in March.
Garden This Month
February is when the indoor garden season truly begins in Wisconsin. The beds outside remain frozen and snow-covered statewide, but under grow lights it's time to start the slowest crops — onions, leeks, celery, and slow perennials and herbs — so they're stout transplants by the time the soil warms in May. Inventory and order any remaining seeds now, and clean, sharpen, and oil tools while there's time.
On a mild thaw day, finish dormant pruning of apples, oaks, and shrubs before the sap rises, and check stored dahlia tubers and bulbs once more for rot. Keep snow banked over perennial beds as insulation; February's freeze-thaw swings, especially in the south where Lake Michigan moderates the cold, can heave shallow-rooted plants if the protective cover is lost too early.
Zone 4a (north-central Wisconsin): still deep winter — keep snow banked over beds and resist the urge to uncover. Late this month, start the slowest seeds indoors under lights: onions, leeks, and celery for transplants you'll set out in late May.
Zone 5a (south-central & Madison area): begin onions, leeks, and early perennials from seed indoors, and prune apples, oaks, and dormant shrubs on a thaw day. The soil is still frozen, so all outdoor planting waits.
What's at the Farmers Market
Wisconsin's indoor winter markets carry through February, and the storage harvest is still going strong. Expect storage onions, garlic, potatoes, carrots, beets, parsnips, cabbage, and winter squash alongside cold-storage apples and the state's signature cheeses and dairy. Heated greenhouses and hoop houses supply fresh microgreens, spinach, and salad mix even in deep winter.
Watch for the first jugs of fresh maple syrup appearing late in the month as warm days and freezing nights start the sap running in the southern sugarbushes — the earliest truly seasonal product of the Wisconsin year. Preserved goods, honey, eggs, and last year's frozen Door County cherries and berries round out the offerings. Store roots cool and humid and squash cool and dry to keep them eating well into spring.
Night Sky This Month
February offers some of the finest stargazing of the Wisconsin year — long, cold, crystalline nights with the winter constellations riding high. Orion stands due south in the early evening, flanked by his Great Nebula, a hazy glow in the sword visible in binoculars from a dark site. The brilliant Winter Hexagon — Sirius, Procyon, Pollux, Capella, Aldebaran, and Rigel — dominates the sky, and the Milky Way arches faintly through it overhead.
By late evening, the sky begins its seasonal turn: Leo rises in the east, a herald of spring, while the Big Dipper swings high in the northeast. On clear, dark nights from the northwoods and Door County's Newport State Park, an active sun can throw the aurora borealis across the northern horizon.

Butterflies & Pollinators
February remains too cold for any butterfly activity in Wisconsin — snow lies deep statewide, and the insects are all in winter dormancy. Monarchs are still clustered in their Mexican overwintering forests, not yet beginning the multi-generation journey that will eventually bring their great-grandchildren back to Wisconsin's milkweed in late spring. Closer to home, mourning cloaks and eastern commas wait out the cold as adults tucked behind loose bark and in unheated sheds, their tissues protected by glycerol antifreeze; red admirals and great spangled fritillaries overwinter as chrysalides and tiny caterpillars. The angle of the strengthening February sun matters: a freak 50-degree thaw late in the month can occasionally coax a mourning cloak out to flap briefly over the snow, the first butterfly of the Wisconsin year, though true emergence usually waits for March or April.

Trees This Month
Wisconsin's trees are still dormant in February, but change is stirring within them. The sugar maples that define the state's hardwood forests will soon begin moving sap as the daily freeze-thaw cycle starts — the engine of the maple syrup season just ahead. Silver maples and willows show the first swelling of their flower buds, and the catkins of hazelnut, alder, and aspen lengthen on warm days.
The conifers hold the winter landscape together: white pine, red pine, balsam fir, and white spruce stand dark green against the snow across the north. Bare-branched tamaracks still mark the bogs, and the marcescent leaves of young oaks and ironwood rattle in the cold wind, clinging on until spring growth finally pushes them off.

Weather & Daylight
Across Wisconsin, a typical February day averages a high near 29°F and a low near 10°F, with about 1.1 inches of precipitation — statewide averages from the 1991–2020 U.S. climate normals.
Still deep winter with highs near 29F, but the air feels a touch less brutal as the numbing chill starts to loosen its grip.
| Average high | 29°F |
|---|---|
| Average low | 10°F |
| Precipitation | 1.1 in |
| Sunrise (mid-month) | 6:59 CT |
| Sunset (mid-month) | 17:27 CT |
Figures are statewide averages over the 1991–2020 U.S. climate normals; local conditions vary with elevation and distance from the coast. Sunrise and sunset are computed for a midstate point on the 15th (CT).
