The Sonic character's favorite seasons
Sonic - Spring. Because it’s easier to run after the harsh winter season and all of it’s ice making surfaces slippery. Also, ALL THAT NATURE.
Tails - Winter. Because Christmas (Which is canonically something that he loves) and the prospect of sitting by the fire and sipping hot chocolate.
Amy - Summer. All that lovely soft-serve ice cream and fair weather.
Knuckles - Autumn. Time for the harvest.
