I hope you do some serious Feb-March weather checking. There are some surprises. That warm ocean current wraps along a lot of Europe. Just as an example, Bilbao, Spain has 61˚/43˚ for March high/low. Way up the Norwegian coast has surprisingly good weather.
I've left a foot+ of ice/snow in MN and seen daffodils in London and a Lemon Festival in Menton, France.
And then there is the amount of daylight. Southerly destinations of course will net you quite a few more minutes every day.
