Another request

Where are we?  I know I answered this initially, but I was also asked to compare where we were relative to places in the U.S.

We are at about 41º latitude.

Amazingly (to me), that is north of Columbus, Ohio
and just slightly south of Providence, Rhode Island.

So why does the area have subtropical weather?  Being on a peninsula is part of it, winds from the Atlantic over the peninsula are part of it, and being close to the Mediterranean Sea (really the Balearic Sea by the east coast) is part of it.  I am expecting plenty of humidity, mild winters (maybe frost out here in the suburbs), and not much rain.
