2025 Western Monarch Count Results
2025 Western Monarch Count Results
Each year the Xerces Society for Invertebrate Conservation leads the Western Monarch Count, an annual volunteer-driven, community science initiative that monitors overwintering western monarch butterflies along the Pacific coast. Its primary purpose is to track population health, identify trends, and inform conservation actions to protect the western migratory monarch butterfly population.
Approximately 12,260 monarchs were counted across 249 sites during the most recent count held this winter during November and December 2025. While this is an increase from the 9,119 monarchs counted in the previous year, it remains the 3rd lowest tally since the count began in 1997.

Southwest Monarch Study's estimated peak migration dates, based on data from tagged monarchs, will give you an idea of when to expect to see monarchs during fall migration at your latitude. Journey North maintains a map of current monarch sightings that shows when monarchs are being observed across the country.
