Letter from Estela Romero: Real Winter Weather for Monarchs
Dear Friends,
About a month ago, the Monarchs' arrival was heralded, bringing with it a significant drop in temperatures accompanied by occasional light rain. Currently, Mexico is experiencing the impact of several severe cold fronts, expected to persist for at least a couple of weeks.
Monarch overwintering sites are encountering temperatures reaching zero and below zero degrees Celsius, despite intermittent sunny spells during the day. The population status of the Monarchs in the sanctuaries remains uncertain.
El Rosario Sanctuary
At "El Rosario" Sanctuary, the colony remains relatively small, occupying 6 to 8 trees with clusters of varying sizes scattered around. Despite its size, the concentration of Monarchs here is a sight to behold, making it a worthwhile visit, even for those traveling from as far as China this weekend!
The sanctuary is situated at "Los Carrizales," with coordinates 19.6032165 -100.2603232. Guides at "El Rosario" mention a second colony located at a higher elevation, requiring a 3.5-4 hour walk—double the time it takes to reach the currently open colony.
Sierra Chincua Sanctuary
Similar in size to "El Rosario" Sanctuary, the "Sierra Chincua" Sanctuary boasts a unique layout. As the afternoon sun moves westward, it magically illuminates the wings and clusters in vibrant orange hues. Local guides also mention a second uphill colony without providing specific details.
Located in front of "La Cabaña del Japonés," the "Sierra Chincua" Sanctuary's coordinates are 19.6767169 -100.3011042.
As long as this winter remains moderately cold to frigid, the Monarchs are expected to fare well. This aligns with the historical climate of the region, which, before the evident impacts of climate change on hibernation sites, provided an ideal environment for the Monarchs in their Oyamel forests in Mexico.
The winter and accompanying rain are welcomed, as they alleviate the severe drought conditions that the migratory generation has faced in recent years. Updates on colony density and behavior will be provided by Journey North as we enter the peak of the season, surrounded by the rich climate of local traditions and art.
Wishing everyone a Merry Christmas and a Fortunate New Year 2024!
