August is late summer in Virginia — shorebird migration crests on the coast, hummingbirds fatten for departure, and the goldenrod and ironweed take over the meadows. The hot, hazy nights of the Perseids end the month, and the first hawks begin staging on the Eastern Shore.
Week by week in August
July 30 – August 5
- Common nighthawks begin streaming over Virginia towns at dusk, and ruby-throated hummingbirds fatten at jewelweed and feeders.
- Goldenrods light the fields beside the deep purple of ironweed and the dusty-pink domes of joe-pye weed.
- Tomatoes hit their peak — choose heavy, fragrant fruit and keep it on the counter, never the refrigerator.
August 6–12
- The Perseid meteor shower peaks around August 12 — the year's most popular shower, best after midnight from a dark Eastern Shore field.
- Fall shorebird migration crests at Chincoteague — semipalmated sandpipers, yellowlegs, and black-bellied plovers crowd the flats.
- The last summer monarch brood feeds on milkweed as the first southbound individuals drift toward the Eastern Shore.
August 13–19
- Songbird migration is quietly underway, and common nighthawks stream south in loose flocks over the towns at dusk.
- Markets are at their fullest — peak tomatoes, sweet corn, melons, and the juiciest Virginia peaches all at once.
- Set out fall brassica transplants and direct-sow lettuce, spinach, and carrots as the soil begins to cool late in the month.
August 20–26
- Asters begin to open among the goldenrod, and the giant pink swamp rose-mallow lights the brackish Tidewater edges.
- Common buckeyes reach their late-summer peak in the old fields and dunes as migratory cloudless sulphurs push north.
- The black gum (tupelo) flushes deep red along the swamp edges — always Virginia's earliest tree to turn.
August 27 – September 2
- The first raptors and morning songbird flights begin staging toward the Kiptopeke funnel on the Eastern Shore.
- Plant garlic later this season, but now sow cover crops and a last round of fall greens as the heat finally eases.
- The first green peanuts from Southside Virginia's Wakefield–Suffolk belt arrive as apples begin their long run.
Birds This Month
August is the heart of fall shorebird migration on Virginia's coast. At Chincoteague and the Eastern Shore impoundments, the mudflats fill with southbound semipalmated and least sandpipers, short-billed dowitchers, lesser and greater yellowlegs, pectoral sandpipers, and black-bellied plovers, while whimbrel stage on the marshes. Post-breeding herons, egrets, glossy ibis, and black and least terns crowd the Tidewater wetlands.
Inland, songbird migration is quietly underway: warblers begin trickling south through the woods, and ruby-throated hummingbirds fatten at jewelweed and feeders before their Gulf crossing, with a late-month surge of migrants. Common nighthawks stream over at dusk in loose flocks, especially late in the month — one of the season's great spectacles over Virginia towns. Chimney swifts mass at roosts, and the first early raptors — bald eagles and ospreys — begin staging toward the Kiptopeke funnel on the Eastern Shore.
What's Blooming
August turns Virginia's meadows gold and purple as the late-summer composites take over. Goldenrods of many species light the fields and roadsides, joined by the deep purple of New York and tall ironweed, the dusty-pink domes of joe-pye weed, and the white flat-tops of boneset and thoroughwort. Wild sunflowers, black-eyed Susan, mountain mint, and the spires of blazing star (liatris) fill the Piedmont grasslands.
Along streams and seeps, the brilliant red cardinal flower and the blue great lobelia bloom together, drawing hummingbirds, with jewelweed spangling the shaded wet ground. In the Tidewater marshes the giant pink swamp rose-mallow, pickerelweed, and the pink plumes of seashore mallow light the brackish edges. The first asters open toward month's end, the opening note of the long autumn bloom that will close the wildflower year.
Garden This Month
August is the bridge between the summer harvest and the fall garden in Virginia. The summer crops keep coming — tomatoes, peppers, okra, eggplant, beans, sweet corn, melons, and sweet potatoes sizing up underground — and the work is steady picking, watering, and disease control in the lingering humid heat. Pull spent, mildewed plants promptly to keep disease from spreading.
This is the prime month to plant the fall garden, which thrives in Virginia's long, mild autumn. Set out transplants of broccoli, cabbage, cauliflower, kale, and collards, and direct-sow lettuce, spinach, arugula, radishes, turnips, beets, and carrots as the soil begins to cool. A second crop of bush beans, cucumbers, and summer squash sown now will mature before frost. Shade new seedlings from the harsh sun, water them faithfully through germination, and keep watching for late hornworms, stink bugs, and the spider mites that flare in dry heat. Sow a cover crop in any beds you're putting to rest.
Zone 6b (Blue Ridge foothills & valleys): the cooler mountain nights ease the late-summer garden. Keep harvesting, sow fall greens, spinach, and turnips, and set out fall brassica transplants early enough to mature before the mountains' earlier frost.
Zone 7a (Piedmont & Shenandoah Valley): the fall-garden window. Transplant broccoli, cabbage, and kale, direct-sow lettuce, spinach, radishes, carrots, and turnips, and keep summer crops watered and harvested as nights begin to cool late in the month.
Zone 8a (Tidewater & lower coast): still hot, with a long fall ahead. Sow fall brassicas, beans, cucumbers, and squash for a second crop, start fall greens in the shade, and keep up the heat-loving okra, southern peas, and sweet potatoes.
What's at the Farmers Market
August markets are at their fullest in Virginia, with summer and the first fall crops overlapping. Tomatoes are at their absolute peak — heirlooms in every color — alongside sweet corn, peppers, eggplant, okra, summer squash, cucumbers, green beans, melons (watermelon and cantaloupe), butter beans, and the first winter squash. The fruit is superb: Virginia peaches at their juiciest, plus blackberries, figs, and the earliest apples.
On the coast the Chesapeake blue crab harvest continues strong. Choose tomatoes that are heavy and fragrant and keep them on the counter, never the fridge; pick melons that are heavy for their size with a sweet aroma at the stem end; and buy peaches that give slightly at the seam, ripening hard ones on the counter and refrigerating once soft. Pick sweet corn you can eat the same day, and keep blue crabs cold, damp, and lively, cooking them the day you buy them.
Night Sky This Month
August is one of the best stargazing months of the Virginia year, crowned by the Perseid meteor shower, which peaks around August 12. The Perseids are the most popular shower of the year, throwing dozens of bright, fast meteors an hour from a dark sky — best after midnight from a Blue Ridge overlook on Skyline Drive or the open dark of the Eastern Shore, away from the Hampton Roads and Northern Virginia light domes.
The summer Milky Way is at its glorious best, arching overhead from Sagittarius and Scorpius in the south through the Summer Triangle of Vega, Deneb, and Altair and on into Cassiopeia in the northeast. Sweep the star clouds with binoculars for the Lagoon Nebula and the rich clusters of Scutum and Sagittarius. As the nights finally begin to lengthen and cool, viewing turns comfortable again. The printable Virginia night-sky guide lists this year's exact meteor-peak dates and planet positions for your region.
Butterflies & Pollinators
August is the peak of butterfly abundance in Virginia, with broods overlapping across the flowery late-summer meadows. Monarchs are building toward their famous migration — the last summer brood is feeding on milkweed now, and the first southbound individuals begin drifting toward the Eastern Shore. The common buckeye is at its most numerous in the old fields and dunes, and migratory cloudless sulphurs and long-tailed skippers push north into the warm Tidewater.
The swallowtails remain abundant — eastern tiger, black, spicebush, pipevine, and zebra — alongside great spangled and variegated fritillaries, red-spotted purples, hackberry emperors, and clouds of skippers (fiery, sachem, and Peck's among them) on the goldenrod, ironweed, and mountain mint. Gulf fritillaries and the occasional American snout appear. The late-summer nectar bloom — joe-pye weed, ironweed, goldenrod, and zinnias — keeps a native garden in constant motion through the hot afternoons.

Trees This Month
August holds Virginia's forest in full, dark late-summer green, the canopy heavy and the seed crop ripening fast. The crepe myrtles of the Tidewater carry on their long bloom, and a few sweetbay magnolias still open scattered flowers, but the trees' energy now goes into fruit. Wild black cherry hangs dark with fruit the birds strip, elderberry ripens purple-black, and the first persimmons color orange (though they stay astringent until frost).
The mast crop builds toward fall: acorns swell and begin dropping from the early white oaks, the hickories and black walnuts fatten, the tulip tree and sycamore set their seed, and the flowering dogwood berries redden in the understory. The dry, hot end of summer flags the first stressed trees into early color, and the black gum (tupelo) — always Virginia's earliest to turn — begins to flush deep red along the swamp edges, the opening note of the great autumn show to come.
