Monarch Butterflies in Pismo: When and Where
Updated: 2 days ago
On a cool morning in late fall, the eucalyptus grove at the south end of Pismo Beach looks like any other stand of trees, until the sun hits a branch and what you thought was a cluster of dead leaves opens into hundreds of orange wings. The Pismo State Beach Monarch Butterfly Grove is one of the best-known overwintering sites for western monarchs, and it is a few minutes from neighborhoods where our clients live. This is how to see the monarch butterflies in Pismo Beach at their best, and what it means to have them in your backyard.
LATE-OCTOBER ARRIVALS · EARLY-WINTER PEAK · LATE-WINTER DEPARTURE
When the monarchs are here
Western monarchs migrate to the California coast to spend the winter, and the grove at Pismo is one of their traditional stops. They begin arriving in the fall, typically from late October into November, the population builds through the early winter, and they leave in late winter as the days lengthen, usually by the end of February or early March. The peak, when the clusters are largest, generally falls in the heart of winter.
The number of butterflies varies dramatically from year to year. Some winters the grove holds a spectacular population and some winters it is sparse, which is part of why the annual counts get so much attention. We would never promise a specific number. What we can tell you is that in a good year, standing under a cluster the size of a beach towel is one of the more remarkable things you can do on a weekday morning on the Central Coast.
HIGHWAY 1 · NORTH BEACH CAMPGROUND
Where the grove is and how to visit
The grove sits along Highway 1 at the southern edge of Pismo Beach, next to the North Beach Campground, essentially at the seam between Pismo Beach, Grover Beach, and Oceano. It is part of Pismo State Beach, and the state park and a group of volunteer docents manage it. There is no admission, and parking is along the highway and in nearby lots, which fill on sunny weekend afternoons in the peak weeks.
A few things that make a visit better:
Watch the temperature. On cold mornings the butterflies cluster tightly and barely move, which is beautiful in its own way. When the day warms, they begin to fly, and the grove fills with movement. Late morning into early afternoon on a mild, sunny day is usually the sweet spot for seeing both.
Bring binoculars. The clusters are high in the trees, and the docents set up spotting scopes, but your own pair means you can look wherever you want.
Talk to the docents. The volunteers know the season's counts, where the clusters have shifted that week, and the life cycle of the butterflies. A five-minute conversation will change how you see the grove.
Stay on the paths. The grove is a protected habitat, and the trees themselves are sensitive to trampling around their roots.
Go on a weekday. Like everything in the Five Cities, the grove is calm on a Tuesday and busy on a Saturday.
We have taken visiting parents, restless kids, and clients waiting for an inspection report to the grove. It has never once failed to change the mood of the day.
THE OCEANO DUNES · THE OCEANO LAGOON · NORTH BEACH
Why the grove matters beyond the butterflies
For anyone thinking about living in the Five Cities, the grove is a small example of something larger about this part of the coast: the wild parts are woven directly into the towns. The same short stretch of Highway 1 gives you the butterfly grove, the North Beach campground, the entrance to the Oceano Dunes, and the boardwalk through the Oceano Lagoon, all within a few minutes of ordinary residential streets in Grover Beach and Oceano.
That is what people mean when they say the Five Cities feel like a beach community rather than a beach resort. Our guide to living in Grover Beach explains why that town, right next to the grove, has become one of the most sensible addresses in the area, and living in Oceano covers the neighbor to the south.
MORRO BAY · LOS OSOS · BACKYARD GARDENS
Monarchs elsewhere on the Central Coast
Pismo has the largest and best-known grove in San Luis Obispo County, but it is not the only one. Smaller overwintering sites exist in eucalyptus stands along the coast toward Morro Bay and Los Osos, and monarchs pass through gardens across the county in fall and spring. If you have a yard, planting the nectar sources that bloom in fall and early spring gives migrating butterflies a place to refuel. Our post on native plants for SLO County yards includes choices that pollinators actually use, and drought-tolerant gardens do double duty here.
One caution we share because the docents share it: avoid planting non-native tropical milkweed on the coast. It can disrupt the migration by encouraging monarchs to breed in winter rather than move on. Native milkweed inland, and nectar plants on the coast, is the general guidance, and the grove's volunteers can point you to current recommendations.
Making the grove part of your year
Locals treat the monarch season the way they treat the elephant seals up the coast: a reason to get outside in the quiet months, a place to bring guests, and a marker of the year turning. The ideal Five Cities winter day is a morning at the grove, a walk on the beach from the campground toward the pier, and lunch in downtown Pismo or Grover Beach before the afternoon fog or the afternoon sun, depending on the week.
If you are visiting to decide whether this part of the coast fits you, come in the monarch months. You will see the Five Cities without the summer crowds, the butterflies in the grove, and the beach nearly empty, and you will understand why so many of our clients who came for a vacation ended up staying. Our guide to living in Pismo Beach as more than a tourist town is the natural next read, and when you want to see homes within walking or biking distance of the grove and the beach, tell us what you are looking for and we will put a day together.
