March is the height of spring in Nevada's Mojave south and the awakening of the Great Basin north. Sage-grouse leks reach their peak, the desert bloom around Red Rock Canyon and Las Vegas explodes in a wet year, and the first northbound migrants begin pouring through the wetland oases.
Week by week in March
February 26 – March 4
- Greater Sage-Grouse leks approach their peak across the northern and eastern sagebrush; mountain bluebirds begin returning to nest.
- The Mojave desert bloom accelerates in a wet year — brittlebush, globemallow, and Mojave aster color the Red Rock Canyon bajadas.
- Leo the Lion with bright Regulus climbs in the east as Orion begins his slow slide toward the western horizon.
March 5–11
- Spring migration accelerates as American white pelicans and the first shorebirds return to the Lahontan Valley wetlands.
- Peak Mojave wildflower season — golden brittlebush, apricot globemallow, beavertail cactus, and carpets of desert gold around Las Vegas.
- Southern Nevada's main warm-season window opens — set out tomato and pepper transplants and direct-sow beans and squash.
March 12–18
- Mountain bluebirds flash electric blue across the pinyon-juniper, and sage thrashers and Brewer's sparrows begin singing on the sage.
- Painted ladies stream north through the Mojave in numbers in a wet year, joined by Sara orangetips and desert orangetips on the bloom.
- Fremont cottonwood breaks bud along the warm Mojave watercourses, and the Joshua trees may push their creamy flower spikes.
March 19–25
- Lucy's warblers arrive in the southern mesquite as the desert dawn chorus builds around Red Rock Canyon.
- The Great Basin north begins to wake — sagebrush buttercup, biscuitroot, and phlox appear on warm south-facing slopes.
- The spring equinox balances day and night; faint galaxies in Leo and Virgo reward a telescope under dark Nevada skies.
March 26 – April 1
- Shorebirds pour into Stillwater NWR — American avocets, black-necked stilts, and dowitchers stage on the Lahontan Valley mudflats.
- Reno and Carson soil finally works as frost leaves the ground — direct-sow peas, spinach, and radishes and plant onion sets and potatoes.
- Quaking aspen swell their buds in the high canyons while the southern cottonwoods shed cottony seed.
Birds This Month
March is one of Nevada's most exciting birding months. The signature event is the Greater Sage-Grouse lek season at its peak — at dawn across the northern and eastern sagebrush, males gather on traditional strutting grounds, fanning their spiky tails and popping their yellow air sacs. Spring migration accelerates: the Lahontan Valley wetlands at Stillwater NWR and Carson Lake fill with staging tundra swans, northern pintail, American white pelicans, and the first shorebirds, and Ruby Lake NWR swells with returning waterfowl.
In the pinyon-juniper foothills, mountain bluebirds (the state bird) flash electric blue as they return to nest, and sage thrashers and Brewer's sparrows begin singing on the sage. The Mojave south is in full spring: Costa's hummingbirds and black-throated sparrows set up on the bajadas, Lucy's warblers arrive in the mesquite, and Gambel's quail pairs scurry the washes around Red Rock Canyon. Raptors stream north overhead, and the desert dawn chorus builds by the day.
What's Blooming
March is peak desert wildflower season in southern Nevada — and in a wet year, one of the great shows of the Southwest. The Mojave bajadas and washes around Red Rock Canyon, the Las Vegas valley, and Lake Mead blaze with golden brittlebush, apricot desert globemallow, Mojave aster in lavender, desert marigold, magenta beavertail cactus, and carpets of desert gold and desert dandelion. The Joshua trees may push their creamy flower spikes, and Mojave yucca and Indian paintbrush color the slopes.
The Great Basin north lags behind but begins to wake. Snow recedes from the valley floors, and the earliest sagebrush-country flowers appear on warm south slopes — sagebrush buttercup, the first biscuitroot (Lomatium), and phlox in mats. In Reno and Carson City gardens, daffodils, tulips, forsythia, and flowering quince bloom. The desert's display depends entirely on winter rain; a wet winter means a March superbloom on the Mojave, a dry one a sparse and fleeting season.
Garden This Month
March is full-tilt spring planting in southern Nevada and the awakening of the northern garden. In the Mojave south, Las Vegas and Pahrump gardeners are in the main warm-season window: set out tomato, pepper, and squash transplants, direct-sow beans, corn, melons, and cucumbers after mid-month, and rush them along before the searing low-desert summer cuts the season short by June.
In the cold north — Reno, Carson, Elko — the soil finally begins to work as frost leaves the ground. Direct-sow peas, spinach, radishes, carrots, and lettuce, plant onion sets, potatoes, and bare-root asparagus, and start tomatoes and peppers under lights for transplanting in May after the last frost. Amend the alkaline high-desert soil with compost, set up windbreaks, and watch the wide day-night temperature swings — a warm March afternoon can give way to a hard frost overnight across the Great Basin.
Zone 6b (Pahrump & southern transition): plant cool-season crops in earnest and start warm-season transplants; the desert heat builds fast, so get tomatoes and peppers established before May.
Zone 7a (Reno & western valleys; cold-pooled Carson Valley floors run colder): the soil begins to work. Direct-sow peas, spinach, radishes, and lettuce, plant onion sets and potatoes, and start warm-season seedlings indoors; the last hard frost is still weeks away, so protect tender sowings.
Zone 9a (Las Vegas valley): the main spring planting window. Set out tomatoes, peppers, and squash transplants, direct-sow beans, corn, melons, and cucumbers after mid-month, and finish the cool-season harvest before the heat shuts it down.
What's at the Farmers Market
March markets in Nevada are bridging the gap between winter storage and the first spring growth. The south's farms and the year-round Las Vegas-area markets lead, cutting cool-season lettuces, spinach, arugula, radishes, green onions, peas, and carrots, with the last of the desert citrus. The northern valleys are mostly between seasons, offering the tail end of storage onions, potatoes, and apples alongside greenhouse greens and microgreens.
Local desert honey, farm eggs, and dried beans and grains continue to fill the stalls. Choose spring greens crisp and unwilted, with bright color and no yellowing, and refrigerate them damp; pick green onions and radishes with fresh, perky tops. The big Nevada specialties — Fallon cantaloupe, sweet corn, and field tomatoes — are still months from harvest, so March is a month of tender early greens and the dwindling winter pantry.
Night Sky This Month
March balances the long-night dark sky with mild, comfortable observing temperatures across Nevada. The state's premier dark-sky destinations — the International Dark Sky Park at Great Basin National Park, the Massacre Rim Dark Sky Sanctuary in the northwest, and the wide basins around Tonopah — offer some of the darkest skies in the country, and the desert outside Las Vegas opens to a star-filled sky within an hour's drive. The spring equinox marks the balance of day and night.
The sky is in transition: Orion and the winter stars sink toward the western horizon after dark while the spring constellations rise — Leo the Lion with bright Regulus climbs in the east, and the Big Dipper rides high, its handle arcing to orange Arcturus. This is a fine month to hunt faint galaxies in Leo and Virgo from a dark Nevada site, since the bright Milky Way band lies low. The printable Nevada night-sky guide details this year's planet positions and best viewing dates.
Butterflies & Pollinators
March brings Nevada's first real flush of butterflies, led by the Mojave south. As the desert bloom peaks around Red Rock Canyon and the Las Vegas valley, painted ladies can stream through in big numbers in a wet year, joined by Sara orangetips, Becker's white, checkered whites, desert orangetips, and the small dark Mojave sootywing on the saltbush. Spring azures and marine blues dance over the flowering bajadas, and the first black swallowtails appear.
In the warming Great Basin north, the mourning cloak patrols riverbanks, and the first Becker's whites, orange sulphurs, and spring whites emerge on the sagebrush flats and in the valleys around Reno and Carson City. The high ranges stay snowbound. A wet winter that fed the desert annuals produces a March surge of butterflies on the Mojave; a dry one keeps numbers thin. Watch the flowering brittlebush and globemallow for nectaring activity, and plant native nectar sources to support the spring fliers in southern gardens.
Trees This Month
March stirs Nevada's deciduous trees as the south leafs out and the north begins to wake. Along the warm Mojave watercourses and Las Vegas streets, Fremont cottonwood breaks bud and unfurls its first green, the catkins shedding cottony seed by month's end, and the desert willow, mesquite, and palo verde begin to green. In a good year the Joshua trees push their creamy flower clusters, and ornamental almond, plum, and apricot bloom in town.
The evergreen single-leaf piñon (state tree) and Utah juniper carry the foothill woodland, the juniper finishing its pollen shed. In the cold north, the cottonwoods, quaking aspen, and willows along the Truckee, Carson, and Walker rivers redden their twigs and swell their buds, with leaf-out still weeks off in the high valleys. On Wheeler Peak, the ancient bristlecone pines remain locked above the snow line. The trees mark Nevada's steep elevation gradient — green stirring on the low Mojave while the high ranges sleep on.
Weather & Daylight
Across Nevada, a typical March day averages a high near 55°F and a low near 30°F, with about 1.1 inches of precipitation — statewide averages from the 1991–2020 U.S. climate normals.
Raw and unsettled, mornings near freezing warm into mild mid-50s afternoons while frequent light rain hints at spring's slow arrival.
| Average high | 55°F |
|---|---|
| Average low | 30°F |
| Precipitation | 1.1 in |
| Sunrise (mid-month) | 6:59 PT |
| Sunset (mid-month) | 18:54 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).
