Helen Bevington said this quote

The seasonal urge is strong in poets. Milton wrote chiefly in winter. Keats looked for spring to wake him up (as it did in the miraculous months of April and May, 1819). Burns chose autumn. Longfellow liked the month of September. Shelley flourished in the hot months. Some poets, like Wordsworth, have gone outdoors to work. Others, like Auden, keep to the curtained room. Schiller needed the smell of rotten apples about him to make a poem. Tennyson and Walter de la Mare had to smoke. Auden drinks lots of tea, Spender coffee; Hart Crane drank alcohol. Pope, Byron, and William Morris were creative late at night. And so it goes.
