Eastern Point during the Monarch’s southward migration in late summer.
The first Monarchs of Spring 2014 have been sighted in Massachusetts (Kingston), as has emerging milkweed. For the past week, a weather pattern has been in place that is perfect for the Monarchs northward migration. Powerful south winds pumped warm air northward and in conditions such as these, Monarchs are carried from southern regions more quickly northward.
Below is a map from the Journey North website illustrating favorable wind patterns for Monarchs.
