Kansas Nature Guide: August 2026
August is the month of sunflowers and blazing star in Kansas — fields turn gold, the gayfeather spikes purple across the prairie, and the early fall shorebird migration builds at the central marshes under warm, dark late-summer skies.
What to look for this week
- Bald eagles gather below the reservoir dams at Clinton, Milford, and Tuttle Creek, fishing the open tailwater as the lakes freeze.
- Order seed now around heat- and drought-tolerant Kansas crops, and plan the windbreak every prairie garden needs.
- The Quadrantid meteor shower peaks around January 3 in a short, sharp burst; look to the northeast after midnight from a dark Flint Hills sky.
- The bare cottonwoods along the creeks hold the conspicuous stick nests of red-tailed hawks against the gray winter sky.
Birds This Month
August is when the fall shorebird migration takes full hold at Kansas's great central marshes. As the water drops on the mudflats of Cheyenne Bottoms and Quivira NWR, returning least, pectoral, Baird's, stilt, and semipalmated sandpipers, lesser yellowlegs, long-billed dowitchers, Wilson's phalaropes, and American avocets gather in great numbers, joined by post-breeding white-faced ibis, egrets, herons, and clouds of Franklin's gulls staging for their journey south.
Songbird migration begins quietly. The first southbound warblers, flycatchers, and orioles slip through the river woods, and the common nighthawks gather into loose evening flocks that swirl over towns late in the month, hawking insects on their way south — a classic late-summer Kansas sight. Chimney swifts begin to mass for migration too.
On the prairie, the breeding season is over but family groups linger — dickcissels, scissor-tailed flycatchers (beginning to flock for departure late in the month), kingbirds, and broods of quail and pheasants. Hummingbird numbers at feeders swell as migrants move through.
This month's tip: the central refuge mudflats are at their best now — go in the cooler morning or evening with a scope, and watch the August skies at dusk for the gathering nighthawks and the first staging swifts.
What's Blooming
August is the month of sunflowers in the Sunflower State. The wild common sunflower — the state flower — blooms in great golden stands along roadsides, in fields, and on waste ground across Kansas, and the cultivated sunflower fields of the central and western counties turn whole horizons yellow. With them, the prairie blazes with the season's signature flowers: the bright purple wands of dotted gayfeather (blazing star) at their peak across the Flint Hills and mixedgrass prairie.
The late-summer prairie is rich and tall — gray-headed and narrow-leaved coneflowers, rosinweed, ironweed with its deep purple-red heads, the first goldenrods and tall asters beginning, snow-on-the-mountain, and wild bergamot all in flower among the curing grasses. The western sand-sage country shows broom snakeweed and plains sunflower. August is the classic Kansas wildflower-photography month — drive the back roads of the Flint Hills or the central counties in the golden evening light, when the sunflowers and gayfeather glow against the prairie.
Garden This Month
August is a double month in the Kansas garden — the summer harvest is still pouring in while the fall garden goes in for the long, mild autumn ahead. Tomatoes, peppers, okra, melons, sweet corn, squash, and beans are at full production in the heat; pick constantly and keep them watered. Okra and southern peas love this weather and produce heavily now.
The crucial work is the fall planting. Early-to-mid August is the window to set out fall broccoli, cabbage, cauliflower, and Brussels sprouts transplants and to direct-sow fall carrots, beets, lettuce, spinach, kale, chard, radishes, and turnips — Kansas's warm autumn and late first frost (October into November) give these crops time to mature, and many sweeten with the first light frosts. The challenge is getting seed up in the August heat: sow a little deeper, keep the soil consistently moist, and shade tender seedlings. Keep watering deeply against the late-summer heat and wind, and start pulling spent summer plants to make room for the fall crops.
Zone 5b (western and north-central Kansas): harvest continues, and the fall window is short here. Set out fall brassica transplants and direct-sow fall lettuce, spinach, radishes, and turnips early in the month so they mature before the earlier western frost. Keep watering deeply through the late-summer heat and wind.
Zone 6a (central Kansas): the prime fall-planting month. Set out fall broccoli, cabbage, cauliflower, and Brussels sprouts transplants, and direct-sow fall carrots, beets, lettuce, spinach, kale, radishes, and turnips. Keep the summer crops picked and watered, and provide shade and steady moisture to get fall seedlings up in the heat.
Zone 6b–7a (eastern Kansas — Kansas City at 6b, Wichita and the southeast at 7a): peak fall planting in the state's longest season. Sow fall greens, roots, and brassicas through the month, keep the summer harvest going, and watch for spider mites and stink bugs in the heat. The long, warm Kansas autumn ahead rewards a generous fall planting now.
What's at the Farmers Market
August is the peak of the Kansas market year, the tables groaning with summer's full bounty. Sweet corn and tomatoes (including heirlooms) lead the way, joined by peppers of every kind, eggplant, okra, summer squash, cucumbers, green beans, onions, potatoes, and the first fall winter squash. This is prime melon season — Kansas cantaloupe and watermelon, especially the famous melons of the southwest, are at their sweetest now.
Summer fruit is abundant — peaches, blackberries, and plums from the orchards — and the first wild and cultivated sunflower seed and bright sunflower bouquets appear at the stalls. Local honey, eggs, grass-fed meats, and stone-ground flour fill out the busy markets in Lawrence, Topeka, Wichita, Manhattan, and Kansas City.
For selection and storage: choose melons that are heavy for their size with a sweet aroma and a creamy-yellow ground spot, and let them finish on the counter. Keep tomatoes at room temperature, stem-side down. Refrigerate corn cold and eat it quickly while sweet, and store peppers, squash, cucumbers, and beans in the crisper, using them within a few days.
Night Sky This Month
August is one of the finest stargazing months in Kansas — warm nights, the magnificent summer Milky Way overhead, and the year's most popular meteor shower. The dark plains skies make all the difference: the Cimarron National Grassland in the far southwest, the open Flint Hills back roads, and the Wilson and Webster reservoir country offer black, horizon-spanning skies where the Milky Way blazes across the whole heaven.
The Perseid meteor shower peaks around August 12, the best and most beloved shower of the year, capable of 50 or more meteors an hour from a dark site, radiating from the northeast and best after midnight. Overhead, the Summer Triangle of Vega, Deneb, and Altair rides high, and the summer Milky Way pours from Cygnus down through Aquila to the star clouds of Sagittarius and Scorpius in the south — the galactic center, dense with nebulae and clusters, perfectly placed from a dark Kansas night.
Because the planets and the exact Perseid peak shift each year, check the printable Kansas night-sky guide for this year's specific viewing nights and planet visibility from your latitude. For the Perseids, find a dark site away from town, lie back, and watch the whole sky after midnight on a clear, moonless night.
Butterflies & Pollinators
August keeps the Kansas prairie rich with butterflies as the late-summer flowers feed huge numbers of nectaring insects. Monarchs are building toward the great fall migration — the late-summer generation that will fly to Mexico is being born now on the milkweed, and their numbers swell across the state. The migrant painted ladies, common buckeyes, and variegated fritillaries are abundant, and the big eastern tiger and black swallowtails work the gardens and timber.
The blazing star and the sunflowers are butterfly magnets now, alive with sulphurs, pearl crescents, gray hairstreaks, fiery and other skippers, and snouts and other brushfoots. The regal fritillaries are fading as their season ends, the last individuals nectaring on the late prairie flowers. To support the gathering monarchs and the prairie species, keep nectar abundant — the gayfeather, sunflower, ironweed, and goldenrod are crucial late-season fuel — and leave milkweed and standing native plants undisturbed, because the monarchs being raised now carry the whole eastern population's fall migration on their wings.
Trees This Month
The Kansas trees endure the last heat of summer in August, in dark, full leaf along the creeks and in town. The eastern cottonwoods still shimmer in the wind over the rivers, but the first dry-stressed and earliest leaves begin to yellow and drop in the late-summer heat, an early whisper of the fall to come. The bur oaks, hackberries, and green ash hold their canopy, though dry years tinge them early.
The fruit and nut crop ripens toward harvest. The black walnuts hang heavy with green-husked nuts in the bottoms, the bur oaks fill with maturing acorns, the hackberries color their small berries, and the Osage orange hedgerows carry their big green hedge-apples toward their autumn drop. In the orchards, the late peaches and early apples ripen. The dark eastern redcedars of the windbreaks set their blue-gray berries, which will feed wintering robins, waxwings, and finches in the months ahead. The slow turn toward fall has quietly begun beneath the lingering summer heat.
