What to look for in nature in New Mexico this October

When do the aspens and cottonwoods turn in New Mexico?

• Aspen Vista and the Santa Fe ski road

  Late September into the first days of October · Hyde Park Road (NM 475) from Santa Fe to Ski Santa Fe

  The Forest Service singles out the Aspen Vista Trail near Ski Santa Fe as one of the Southwest’s signature fall hikes, a closed road climbing through almost pure aspen. Go on a weekday morning, and early in October rather than late.

• The Enchanted Circle

  Late September to early October · Taos, Questa, Red River, Eagle Nest, Angel Fire

  The loop around Wheeler Peak takes in Bobcat Pass above Red River, the Moreno Valley and Taos Canyon. Red River’s station has usually frozen by September 7 and Angel Fire’s by September 8, so color up here comes with frost on the windshield, and Taos’s visitor bureau says the first dusting of snow in town often lands near the end of October.

• Cloudcroft and the Sunspot byway

  October, varying from year to year · Sacramento Mountains, Lincoln National Forest

  In the south, the Forest Service points to the Sunspot Scenic Byway out of Cloudcroft, where aspens, maples and oakbrush color the high Sacramentos. The road is numbered 6563, after the wavelength in angstroms that solar astronomers use to watch the sun, and ends at the observatories at Sunspot.

• Cottonwoods in the bosque and the Gila canyons

  After the aspens; timing varies by river and by year · Rio Grande bosque, Rio Chama, Gila and Mimbres rivers

  The valley trees turn after the mountains finish. A Forest Service summary for Fremont cottonwood, the tree of the Gila and the southern rivers, puts yellowing in late September and leaf drop from mid-October in general terms; the Rio Grande cottonwood of the Albuquerque bosque usually holds its gold later. Treat those as rough windows. The Bosque Ecosystem Monitoring Program collects fallen leaves in tubs every month at sites along the Rio Grande, a good model for a home record: note the week your tree is half gold and the week it is bare.

What is the Albuquerque Box, and what will El Niño do this winter?

• The Albuquerque Box

  Clear, calm mornings; about 3 of the first 15 days of October on average · Balloon Fiesta Park and the middle Rio Grande valley

  After a clear night the ground cools the air above it, and the cold, heavy air drains down the valley from north to south in a layer usually no more than a few hundred feet deep. Above an inversion, a weak south wind often blows the other way. A pilot who launches heads south toward downtown, then climbs into the upper current and drifts back north. The forecast office’s climatology finds a textbook box on roughly three of the first fifteen October days, and the same study notes that dawn at the north-valley launch field often runs five to ten degrees colder than at the airport. Sunlight over the Sandias breaks the inversion and the box dissolves by mid-morning.

• Canyon winds and early storms

  Any October morning with a front east of the mountains · East side of Albuquerque, below Tijeras Canyon

  When high pressure piles up on the plains, air squeezes west through the Tijeras gap; on October 15, 2015, gusts reached 68 mph below the canyon. A system dropping through the Rockies can also bring hail or snow, as it did to Albuquerque and Rio Rancho on October 4–5, 2004.

• The first snow

  Average late November in Albuquerque; earlier in the mountains · Statewide

  At the Sunport the average first snowfall comes on November 29, and the earliest on record fell on October 5, 2004. Write down the day you first see snow on the Sandias, the Sangres or Sierra Blanca.

When do the sandhill cranes come back to New Mexico?

• Sandhill cranes in the valley

  First arrivals at the end of October; peak mid-November to late January · Bosque del Apache; Albuquerque’s Open Space Visitor Center; Bernardo and the Rio Grande farm fields

  Albuquerque’s Open Space Visitor Center on Coors Boulevard farms corn, sorghum, millet and alfalfa for wintering birds and has viewing windows toward the fields and the Sandias. At Bosque del Apache the Tour Loop is open from an hour before sunrise to an hour after sunset, the refuge warns of intermittent road closures from construction that began around September 29, and entry is free on October 11 and October 27. The Festival of the Cranes follows on December 2–5.

• The Manzano HawkWatch is closed this year

  Normally August 27 – November 5 · Capilla Peak, Manzano Mountains

  HawkWatch International has counted migrating raptors from Capilla Peak since 1985, usually 5,000 to 7,000 birds a fall of up to 18 species, with Swainson’s hawks, turkey vultures and sharp-shinned and Cooper’s hawks most common. In 2026 it will not count at all: the Whiskey Fire and the clean-up after it have closed the area, and the Cibola National Forest has closed Forest Road 245 to Capilla Peak and its campground since July 9. The birds still migrate with no one counting them, so any open view of the Manzano or Sandia ridgelines on a clear afternoon may turn up a few.

• Bird walks in the Albuquerque bosque

  Every Saturday and Sunday, 8:30 a.m. · Rio Grande Nature Center State Park, Candelaria Road

  Volunteer naturalists lead a free walk from the Candelaria Wetland blind every weekend morning, with loaner binoculars; the park’s list tops 300 species. As October goes on, look for the first wintering ducks on the wetland and the first juncos and white-crowned sparrows in the brush.

Can you still see the bat flight at Carlsbad Caverns in October?

• Brazilian free-tailed bats

  Around sunset, nightly through October · Carlsbad Caverns National Park

  The colony is mostly Brazilian free-tailed bats, each about half an ounce with an 11-inch wingspan, and numbers change from night to night and season to season. Park counts put the resident summer colony near 400,000 in 2005, with as many as 793,000 bats during the spring and fall migrations. The park calls August and September the best months, when the year’s young and bats passing through from colonies farther north join the flight. By October the evenings are shorter and cooler and the spiral out of the cave comes earlier; what you see on any given night is up to the bats.

• The dawn return

  About 4 to 6 a.m. · Natural Entrance

  Early risers can watch the bats come home, folding their wings and diving into the entrance from hundreds of feet up at 25 mph or more. It is quieter than the evening flight and, for many people, more astonishing.

When is kokanee snagging season in New Mexico?

• Where snagging is open

  October 1 – December 31 · Navajo Lake, the Pine River, El Vado Lake, the Rio Chama below El Vado, Eagle Nest Lake

  The bag limit in the snagging season is 12 kokanee a day, 24 in possession. Any other fish snagged goes straight back. At Navajo Lake the buoyed no-wake areas and shoreline at the Pine River and Simms boat ramps stay closed to snagging all season.

• Heron Lake and Willow Creek wait

  Closed October 1 – November 10; open November 11 – December 31 · Heron Lake and Willow Creek, Rio Arriba County

  These waters close while the department takes eggs, and anglers may not have any kokanee in possession while fishing there during the closure. Even without a rod, a shallow cove full of crimson salmon is a sight worth the drive.

When is the first freeze in New Mexico?

How much daylight does New Mexico lose in October?

What can you see in New Mexico’s night sky in October?

• Jupiter reappears from behind the moon

  Tuesday, October 6, about 3:10–3:11 a.m. MDT · Very low in the east; best from the eastern plains

  Farther east, the crescent covers Jupiter in a dark sky. Here the moon comes up with the planet already behind it. By the International Occultation Timing Association’s tables, Jupiter slides back out from the dark edge at about 3:10 a.m. in Las Cruces and Roswell and 3:11 a.m. in Albuquerque, Santa Fe, Farmington and Clovis. Naval Observatory tables give moonrise at 2:38 a.m. in Clovis and 2:51 in Albuquerque, so the moon stands only 2 to 6 degrees up at the moment, highest on the east side of the state. The Sandias block that part of Albuquerque’s sky and the Sangres block Santa Fe’s; this one belongs to Clovis, Portales, Tucumcari and Roswell, with a flat horizon and binoculars. Everyone else can watch the pair climb together, Jupiter just off the crescent’s dark edge, until dawn.

• Saturn all night

  Opposition October 4; the moon alongside October 23–24 · Rising in the east at sunset

  Saturn reaches opposition on the 4th, so it rises at dusk, rides highest around midnight and sets at dawn, a steady cream-colored light in a sparse part of the sky. Even a small telescope shows its rings. A gibbous moon drifts past it on the 23rd and 24th.

• Draconids in a moonless evening

  Evening of Thursday, October 8 · Face north after dark

  An early-evening shower, so children can stay up for it. In Albuquerque the 4 percent crescent sets at 5:34 p.m., before sunset, and the moon is new two days later, so the whole night is dark. Rates are usually low and occasionally surprising.

• Orionids before dawn

  Active October 2 – November 7; broad peak October 21–22 · Anywhere dark, after moonset

  The waxing gibbous moon sets in Albuquerque at 2:32 a.m. on the 21st and 3:33 a.m. on the 22nd, and dawn twilight begins about 6:52, which leaves three to four dark hours. Rates in a strong year reach 10 to 20 an hour: swift grains shed by Halley’s Comet.

• Venus leaves, Mars meets the Beehive

  Venus in the first days of October; Mars on the morning of October 11 · West after sunset; east before dawn

  Venus hangs low in the western twilight only at the very start of the month, then reaches inferior conjunction on the 23rd, lined up between us and the sun. Before dawn Jupiter blazes in the east; on the 11th, Mars crosses the Beehive star cluster, a fine sight in binoculars.

• The Hunter’s Moon

  Full at 10:12 p.m. MDT, Sunday, October 25; looks full on the 25th and 26th · Low in the east at dusk

  Albuquerque sees it rise at 5:50 p.m. on Sunday, about half an hour ahead of the 6:19 sunset, and at 6:27 p.m. on Monday, a few minutes after sundown, so both evenings it comes up round and orange over the mountains. It is not a supermoon; it is near its average distance.

• White Sands by moonlight

  Sunday, October 25 (Full Moon Night); Monday, October 26 (Moonlight Hike) · White Sands National Park, west of Alamogordo

  The park stays open until 8 p.m. on October 25 for its last Full Moon Night of the year, with a 5:30 p.m. talk on fossilized footprints; no tickets are needed, but allow time for the drive in. The ticketed Moonlight Hike on the 26th starts at 6 p.m. and usually sells out within minutes. Missile range activity or weather can cancel either.

What is blooming, ripening and dropping in New Mexico in October?

• Red chile and ristras

  Early October for the red harvest · Hatch and the Mesilla valley, the Rio Grande valley, backyard gardens

  New Mexico State University’s growing guide calls early October the ideal time to harvest red chile, when most pods are ripe and partly dried and before any frost. A hard freeze on succulent red pods bursts the cells and lets mold in, so the pick is a race against the first cold night. Early-planted fields gave a green harvest in August and then ripened red. Watch for strings of drying pods on porches and fence rails.

• Piñon nuts

  Cones open late September and October · Piñon–juniper woodland statewide

  A two-needle piñon cone needs about two summers to ripen, and the Forest Service’s species review says the cones open in late September and October. Big crops are irregular, every three to seven years, and dry years cut them short, so a heavy crop is news. On the Santa Fe National Forest no permit is needed to gather up to a bushel for personal use. Pick from the ground, and leave plenty for the piñon jays, Steller’s jays, scrub jays and Clark’s nutcrackers that cache the seeds and plant the next generation of trees.

• Chamisa in bloom

  August to November · Roadsides, arroyos and vacant lots statewide

  Rubber rabbitbrush, the chamisa of every New Mexico roadside, is the late-season gold of the lowlands. According to the Lady Bird Johnson Wildflower Center it flowers from August into November, and its dense yellow heads feed bees, butterflies and the occasional late monarch. Navajo people made a yellow dye from the flower heads.

• Monarchs: a mixed picture

  Stragglers into early October · Chamisa and late asters, statewide

  New Mexico sits where the eastern and western monarch migrations blur. The Southwest Monarch Study, which tags butterflies across the region, has found that they do not all winter in the same place; some reach central Mexico and some the California coast. A monarch on chamisa this month is worth a photo and a report.

What are elk, bears and other animals doing in October?

• Elk: the rut winds down

  September into early October · Valles Caldera National Preserve, Bandelier, the Pecos and Sangre de Cristo high country

  The Park Service counts 2,500 to 3,000 elk in the Valles Caldera and calls the fall rut, with sparring bulls and bugling across the meadows, one of the preserve’s biggest draws; at Bandelier rangers describe the bugle as a high whistle in the upper canyons. The calling fades as October goes on and herds start drifting toward lower ground. Watch from the road with binoculars and stay well back from bulls.

• Bears fattening up

  Through October, before denning · Foothills of Santa Fe, Albuquerque, Los Alamos, Ruidoso, Cloudcroft and Raton

  Black bears feed heavily in the fall before they den, and foothill neighborhoods offer easy calories. The New Mexico Department of Wildlife tells foothill residents to remove bird feeders while bears are active, because birdseed is rich and easy. Lock trash away, pick up fallen fruit, and keep pet food indoors.

• New World screwworm near Mimbres

  Detected September 17, 2026 · Grant County and the surrounding surveillance zone

  The U.S. Department of Agriculture confirmed a case of New World screwworm, a fly whose larvae feed on living flesh of warm-blooded animals, near Mimbres in September. The Department of Wildlife asks hunters and anyone outdoors to watch for live or freshly dead animals with maggots or white egg masses in a wound, especially during the rut when bucks and bulls injure one another. Note the GPS location and call the department at 888-248-6866 for wildlife or the Livestock Board at 505-841-6161 for livestock.

• The last crickets

  Until the first hard freeze · Any warm evening

  Field and tree crickets sing slower each cooler night until the cold stops them. For the cricket thermometer page, count a tree cricket for 14 seconds and add 40 to estimate the Fahrenheit temperature; the night the singing stops often falls within a few days of your first freeze.
