August is the height of Nevada's harvest — the famous Fallon 'Hearts of Gold' cantaloupe at its sweetest, the markets overflowing, and the sagebrush sea beginning to gild with rabbitbrush. Fall shorebird migration builds at the wetlands, and the warm nights deliver the Perseid meteors under the desert's dark skies.
Week by week in August
July 30 – August 5
- Fall shorebird migration builds at Stillwater and Ruby Lake — western and least sandpipers, dowitchers, and phalaropes stage on the mudflats.
- The rabbitbrush begins igniting the Great Basin roadsides and sage flats with brilliant gold, and the sagebrush sets its flower heads.
- The first quaking aspen leaves begin to turn at timberline as the pinyon jays start harvesting the ripe pine nuts.
August 6–12
- The Perseid meteor shower peaks around August 12 — one of the year's best, spectacular from a dark desert site after midnight.
- The famous Fallon 'Hearts of Gold' cantaloupe hits its legendary peak in the Lahontan Valley's alkaline soil.
- Painted ladies, sulphurs, and Great Basin wood-nymphs nectar on the blooming rabbitbrush across the Great Basin.
August 13–19
- Post-breeding white-faced ibis, American white pelicans, and herons gather in big flocks at the Lahontan Valley wetlands.
- A late monsoon storm can trigger a brief second bloom on the Mojave bajadas — desert marigold, sand verbena, and spectacle pod.
- Northern valleys overflow — pick tomatoes, corn, melons, and squash at their height and sow fall greens for autumn.
August 20–26
- Family groups of mountain bluebirds, Clark's nutcrackers, and Cassin's finches roam the ranges as breeding ends.
- Monarchs produce the migratory generation in the irrigated valleys — adults that will drift to the California coast to overwinter.
- Markets overflow with the cantaloupe, tomatoes, sweet corn, peppers, peaches, and the first apples of the Nevada harvest.
August 27 – September 2
- Fall migration surges — migrant warblers, tanagers, and flycatchers fuel up in the riparian cottonwoods along the rivers.
- The rabbitbrush blazes brilliant gold statewide and the big sagebrush, the state flower, is in full bloom on the slopes.
- As the worst Mojave heat eases, Las Vegas gardeners begin the prime fall planting window under shade.
Birds This Month
August is dominated by fall shorebird migration through Nevada's wetlands. The Lahontan Valley at Stillwater NWR and Carson Lake, and Ruby Lake NWR, fill with southbound western and least sandpipers, long-billed dowitchers, red-necked and Wilson's phalaropes, marbled godwits, and American avocets staging on the mudflats and shallows — a major Pacific Flyway stopover at its peak. Post-breeding white-faced ibis, American white pelicans, and herons gather in big numbers.
In the high country, family groups of mountain bluebirds (state bird), Clark's nutcrackers, and Cassin's finches roam the ranges, and rufous hummingbirds stream south through the mountain meadows. The sagebrush quiets as breeding ends, with flocking horned larks and sage thrashers. In the hot Mojave, the late-summer monsoon greens the desert and stirs lesser nighthawks, black-throated sparrows, and Gambel's quail coveys in the cooler dawn hours.
What's Blooming
August begins the gilding of the Great Basin. The rabbitbrush (chamisa) ignites the roadsides and sage flats with brilliant gold, one of the signature late-summer sights of northern Nevada, and the big sagebrush (the state flower) sets its small yellow flower heads, releasing its resinous scent after a rain. Mid-elevation slopes still hold sulphur buckwheat, blazing star, asters, goldenrod, and the last scarlet gilia.
In the high country, the alpine bloom is winding down as the first cold nights touch the peaks, though late gentians, asters, and fireweed persist in the Ruby and Wheeler Peak meadows. In the Mojave south, the summer monsoon thunderstorms can trigger a brief second bloom on the bajadas — desert marigold, sand verbena, and spectacle pod flushing after a downpour. August trades the spring flowers for the warm gold of the sagebrush country's late season.
Garden This Month
August is the harvest peak in northern Nevada and the start of the fall reset in the south. The northern valleys — Reno, Carson, Mason — overflow: pick tomatoes, peppers, sweet corn, melons, summer squash, cucumbers, and beans at their height, and lift and cure onions and garlic. Sow the fall garden now — spinach, lettuce, arugula, radishes, and fall greens — so they establish before the early frost, which can arrive in September in the higher valleys.
In the Mojave south, the relentless heat begins to ease late in the month, opening the prime fall planting window: set out tomato and pepper transplants for a fall harvest and sow beans, squash, and cucumbers under shade as temperatures drop from their July extreme. Statewide, keep up deep watering and heavy mulch through the warm, dry weeks, and watch the high northern valleys, where the first frost is never far off after mid-August.
Zone 6a (Elko, Ely & higher north): harvest fast and watch the calendar — the first frost can come by early-to-mid September, so ripen and protect tender crops and pull the last of the warm-season harvest.
Zone 7a (Reno & western valleys; cold-pooled Carson Valley floors run colder): harvest peak and fall sowing. Pick tomatoes, corn, squash, and melons at their height, and sow fall spinach, lettuce, radishes, and arugula for autumn before the frost returns.
Zone 9a (Las Vegas valley): the fall reset begins. As the worst heat eases late in the month, set out tomato and pepper transplants for a fall crop and sow beans, squash, cucumbers, and the first cool-season seeds under shade.
What's at the Farmers Market
August is Nevada's best market month, crowned by the state's signature crop. The Fallon 'Hearts of Gold' cantaloupe — grown in the Lahontan Valley's alkaline soil under big day-night temperature swings that concentrate the sugars — is at its legendary peak, celebrated at Fallon's late-summer Cantaloupe Festival. The markets overflow with tomatoes, sweet corn, peppers, melons, summer squash, cucumbers, beans, sweet onions, garlic, peaches, plums, and the first apples.
Local desert honey, farm eggs, cut flowers, and herbs round out a full table. For the Fallon cantaloupe, choose a melon heavy for its size with a sweet aroma at the stem end and a clean, slightly sunken scar, and hold it at room temperature until fully fragrant. Pick sweet corn with snug husks and plump kernels and keep it cold; choose tomatoes heavy and fragrant and keep them out of the refrigerator. August is the month to eat from Nevada's farms at their fullest.
Night Sky This Month
August is the marquee stargazing month in Nevada — warm nights, the Milky Way blazing, and the year's most-watched meteor shower. The state's dark-sky country is in full season: Great Basin National Park, an International Dark Sky Park, runs nightly summer astronomy programs; the remote Massacre Rim Dark Sky Sanctuary in the northwest is among the darkest skies in the country; and the basins around Tonopah and the desert beyond Las Vegas deliver pristine views.
The summer Milky Way arches overhead from Sagittarius and Scorpius, the galactic center and its great star clouds, nebulae, and globular clusters dazzling from a dark Nevada site. The Summer Triangle rides near the zenith. The headline event is the Perseid meteor shower, peaking around August 12 — one of the year's best and most reliable, radiating from the northeast after midnight, spectacular from a dark desert site. The printable Nevada night-sky guide gives this year's planet positions and the exact peak viewing dates.
Butterflies & Pollinators
August keeps Nevada's butterflies active across all elevations. As the rabbitbrush and late-summer flowers bloom in the Great Basin, painted ladies, West Coast ladies, orange and clouded sulphurs, fritillaries, coppers, Great Basin wood-nymphs, and many blues and skippers nectar on the gold. Western tiger swallowtails work the riparian corridors, and California tortoiseshells drift down from the ranges.
Monarchs are producing the migratory generation in the irrigated valleys now — late-summer adults that will drift toward the California coast to overwinter. In the high country, the last alpine fritillaries and blues fly before the cold. In the Mojave south, the summer monsoon brings a flush of queens, Mojave sootywings, fiery skippers, and desert species to the rain-greened bajadas. The blooming rabbitbrush is a magnet for late-summer butterflies — plant native asters and milkweed to support them and the southbound monarchs.
Trees This Month
August holds Nevada's trees in late summer, the first hints of fall stirring at the highest elevations. The riparian Fremont cottonwood and willow remain dense and green along the rivers, though a few cottonwood leaves begin to yellow in the dry heat. The high quaking aspen groves of the Rubies, Wheeler Peak, and Carson Range are full and green, the very first leaves starting to turn at timberline by month's end.
The evergreen single-leaf piñon (state tree) ripens its pine nuts in the cones across the foothill woodland — a crop that will feed the pinyon jays and people alike in fall — and the Utah juniper sets its blue-gray berry-cones. Up high, the ancient bristlecone pines and the limber pine and Engelmann spruce hold the timberline forest. In the monsoon-greened Mojave south, the mesquite sets its pods, the palo verde holds green, and the Joshua trees stand over the warm desert. The piñon nut harvest is August's quiet story across the Great Basin.
Weather & Daylight
Across Nevada, a typical August day averages a high near 88°F and a low near 56°F, with about 0.5 inches of precipitation — statewide averages from the 1991–2020 U.S. climate normals.
Still sweltering but marginally easing, warm nights near 56 give way to high-80s afternoons and dry, sun-baked stretches.
| Average high | 88°F |
|---|---|
| Average low | 56°F |
| Precipitation | 0.5 in |
| Sunrise (mid-month) | 6:02 PT |
| Sunset (mid-month) | 19:42 PT |
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 (PT).
