Imagine an island located here, describe its climate!
Imagine one of the New England seamounts were actually an island. Same latitude as southern New Jersey but as far away from the Eastern Seaboard as Bermuda.
My take - similar climate to the Azores. Mild enough to support palms. Gulf Stream moderates the climate and makes it warmer than the Azores, potentially warm enough to support Coconut Palms. Perhaps home to the highest latitude Coconut Palms.
Island gets incredibly amounts of rain, particularly in winter. Always on the warm side of Nor’easters bringing high temperatures into the 80’s even in January. Cold fronts are moderated by 600+ miles of warm Atlantic waters between it and the USA.
