WIST

The coldest winter I ever spent was a summer in San Francisco.

Mark Twain (1835-1910) American writer [pseud. of Samuel Clemens]
(Spurious)

Frequently attributed to Twain, but undocumented in any of his writings. The closest is this, in a letter to Lucius Fairchild (28 Apr 1880):

For this long time I have been intending to congratulate you fervently upon your translation to—to—anywhere—for anywhere is better than Paris. Paris the cold, Paris the drizzly, Paris the rainy, Paris the Damnable. More than a hundred years ago, somebody asked Quin, ‘Did you ever see such a winter in all your life before?’ ‘Yes,’ said he, ‘last summer.’ I judge he spent his summer in Paris.
