While it's not a favorite season of mine, this poem is:
Daffodowndilly
by A. A. Milne
She wore her yellow sun-bonnet,
She wore her greenest gown;
She turned to the south wind
And curtsied up and down.
She turned to the sunlight
And shook her yellow head,
And whispered to her neighbour:
"Winter is dead."
From When We Were Very Young
