California Nature Guide: November 2026
November is when winter California arrives — the rains green the hills, the Central Valley fills with wintering waterfowl and cranes, the monarch groves reach their peak, and the new citrus season begins. The dry golden state gives way to the wet green one.
What to look for this week
- Snow geese, white-fronted geese, and pintail jam the Sacramento and San Joaquin valley refuges; sandhill cranes roost near Lodi and Cosumnes.
- San Joaquin Valley navel and Cara Cara oranges and easy-peel Satsuma mandarins are at their winter peak.
- Western monarchs hang in clustered curtains in the coastal groves at Pismo Beach, Pacific Grove, and Natural Bridges.
- The Quadrantid meteor shower peaks around January 3 in a brief, sharp burst, best after midnight from a dark desert site.
Birds This Month
November is when California's spectacular winter birding arrives in full. The Central Valley waterfowl reach overwhelming numbers — the Sacramento and San Joaquin refuges fill with snow and Ross's geese, greater white-fronted geese, northern pintail, shovelers, wigeon, teal, and the rest of the Pacific Flyway's millions, and the dawn fly-outs are at their breathtaking best. The sandhill cranes are back in force at the Lodi and Cosumnes roosts, their bugling fly-ins at dusk a marquee November spectacle.
The wintering land birds settle in: yellow-rumped warblers and ruby-crowned kinglets are everywhere, the brush is full of white-crowned, golden-crowned, and fox sparrows, cedar waxwings strip the berries, and varied thrushes drift down from the north into the coastal forests. Wintering raptors arrive — ferruginous hawks, the occasional rough-legged hawk, merlins, and bald eagles over the valley.
On the coast, the southbound gray whales begin streaming past, wintering loons, grebes, scoters, and brant fill the bays, and the rocky shores host returning black turnstones and surfbirds. The endemic yellow-billed magpies flock in the valley oaks.
This month's tip: the valley-refuge spectacle is back — plan a dawn or dusk visit to a Central Valley wildlife refuge or a crane roost near Lodi, where the sheer numbers of geese, ducks, and cranes are among the greatest wildlife concentrations in North America.
What's Blooming
November is the greening of California, when the first good rains transform the dry golden hills into emerald and the new growing year begins. There are few flowers yet, but the landscape comes alive: the hills flush green with germinating annual grasses and wildflower seedlings, the moss greens on the oak bark and rocks, and the first fungi push up in the woods after the rains. This greening is the true beginning of the long California bloom season.
A few flowers do appear. The early manzanitas begin opening their urn-shaped pink-and-white bells in the chaparral, an important early nectar source, and on warm days the very first California poppies and other opportunistic natives can open on sheltered southern slopes. In the salt marshes of San Francisco Bay, the pickleweed glows red with the season, and the late goldenrod and gumplant finish in the drying grasslands.
Where to look: this is a month to watch the hills turn green and to seek the first manzanita bloom in the chaparral rather than a true wildflower display. Walk a foothill or coastal trail after a rain and look for the green carpet of seedlings, the first manzanita bells, and the reddened Bay marshes — the quiet, hopeful start of the new California flower year.
Garden This Month
November is a productive month in the California garden as the rains arrive and the cool-season crops thrive. In the mild coast and valley zones, the winter vegetable garden is in full swing — harvest broccoli, cauliflower, lettuce, kale, chard, and root crops, and there is still time to sow peas, fava beans, spinach, cilantro, and quick greens for a continued winter harvest. This year-round vegetable garden is one of the great rewards of California's mild climate.
With the rains returning, November is one of the best months to plant California native plants, trees, and shrubs — set out now, they establish on the natural winter moisture and need little irrigation in years to come. As nurseries stock bare-root roses, fruit trees, and cane berries late in the month, the dormant-planting season begins. Mulch beds to protect against the occasional valley frost, clean up fallen leaves and spent plants to reduce pests, and let the rains do the watering. In the foothills and Sierra, harvest ahead of hard frost and put the garden to bed.
Zone 10a (mild coast, Los Angeles basin): the frost-free coast grows straight through — keep sowing and harvesting cool-season crops, and plant natives and cool-season flowers on the rains. Watch for the rare coastal cold snap, but the mild marine climate keeps the winter garden productive all month.
Zone 8a (Sierra foothills, higher inland): frost has settled in at elevation — harvest any remaining tender crops, protect cool-season greens with row cover, and finish planting garlic and bulbs. Mulch perennials heavily and put the higher-elevation garden to bed for winter.
Zone 9b (Central Valley, inland Southern California): the cool-season garden is in full swing — harvest broccoli, lettuce, and greens, and there is still time to sow peas, fava beans, spinach, and quick greens. With the rains arriving, this is a prime month to plant California natives, trees, and shrubs, and to plant bare-root stock as it appears.
What's at the Farmers Market
November marks the handoff from fall harvest to winter citrus at the California market. The new citrus season begins in earnest — the first sweet navel oranges and easy-peel Satsuma mandarins arrive from the San Joaquin Valley, joined by Meyer lemons and the first kumquats. The fall fruits hold on: persimmons (Fuyu and Hachiya), pomegranates, late apples, and Asian pears are at their best.
The cool-season vegetables come into their prime: sweet, frost-improved broccoli, cauliflower, Brussels sprouts from the Central Coast, cabbages, kale, chard, and a rainbow of winter squash and sweet potatoes. The nut harvest — fresh-crop walnuts, almonds, and pistachios — is in the markets, and the new-crop olive oil from California's groves appears.
For selection and storage: choose mandarins and oranges heavy for their size with firm skin and store them cool; pick persimmons by type (firm Fuyu to eat crisp, soft Hachiya); buy winter squash with hard rinds and intact stems for long keeping; refrigerate or freeze shelled nuts. November markets are a satisfying mix — the last fall fruit, the first winter citrus, the sweet cold-weather brassicas, and the fresh nut crop all at once.
Night Sky This Month
November brings California long, dark nights and, between the autumn storms, some of the clearest skies of the year. The dark-sky destinations are excellent: Death Valley and Joshua Tree in the cool desert nights, Anza-Borrego, and the southern Sierra before the heavy snows close the high passes. The crisp post-rain air can deliver superb transparency, and the long nights mean stargazing starts early.
The autumn constellations rule the evening — the Great Square of Pegasus rides high in the south, leading Andromeda with its faint naked-eye galaxy (a fine binocular target from a dark site) and the W of Cassiopeia overhead. By mid-evening the brilliant winter sky begins to climb in the east: the Pleiades cluster, orange Aldebaran in Taurus, and bright Capella rise, and later Orion clears the horizon, signaling the great winter show to come.
The Leonid meteor shower peaks around November 17, a modest shower in most years (with rare spectacular storms), best after midnight from a dark desert site. For this year's exact prospects and planet positions, see the printable California night-sky guide, tailored to the state's latitudes.
Butterflies & Pollinators
November is the peak of the western monarch overwintering season in California, the month the coastal groves are at their fullest. Monarchs cluster by the thousands in the eucalyptus, Monterey pine, and Monterey cypress at Pismo Beach, Pacific Grove, Santa Cruz's Natural Bridges, and dozens of sites along the Central and Southern California coast. On cool mornings they hang in motionless orange curtains; when the sun warms the grove, they spill into flight to drink and bask — the great accessible wildlife spectacle of the California coast in late fall.
Away from the groves, the butterfly year is winding down. A few hardy species fly on warm afternoons — the last gulf fritillaries, cabbage whites, fiery skippers, and buckeyes in mild coastal and Southern California gardens — and the mourning cloak and California tortoiseshell tuck into bark crevices and woodpiles to overwinter as adults.
To help them: visit a monarch grove respectfully in November, when the clusters are largest, and support keeping these irreplaceable coastal stands of trees standing. In the garden, leave the leaf litter, brush, and woodpiles that give overwintering butterflies shelter, keep a little late nectar blooming for the few on the wing, and never disturb the resting clusters at the overwintering sites.
Trees This Month
November is the late-autumn turning for California's trees, the rains reviving them and the last fall color holding on. The eastern Sierra aspen show has finished, but in the lowlands the deciduous trees color and drop their leaves — the foothill black oaks turn gold, the valley's cottonwoods and sycamores yellow along the rivers, and the city's non-native liquidambars, Chinese pistache, and ginkgos light up the streets with red and gold.
The rains stir the dry-season survivors back to life. The coast live oaks and valley oaks have dropped their acorns and now drink the returning moisture, and the soil softens for the planting season. On the coast, the coast redwoods shift from fog-reliance to the welcome winter rains, and the Pacific madrone holds its evergreen leaves and ripening red berries that feed wintering birds. In the high Sierra, the conifers and the great giant sequoias stand ready for the snow that will refill the snowpack, their year of growth finished as winter closes in on the high country.
