Sunny in London today and not exactly cold, but definitely crisp along the river. I walked from St. Paul's to the Tate Modern, crossing the Millennium Bridge, formerly known as the "wobbly bridge". (That's because when it was first opened, it wobbled and they had to close it for some time while it was stabilized.) Then I walked along the Thames and to Waterloo. It felt almost springlike, but I wouldn't want to be overly optimistic about that.
