In my fictional setting, I follow Earth's seasonal settings but this doesn't necessarily have to be the case. After all our northern and southern hemispheres are in opposition to one another here - spring in one hemisphere is autumn in another and so on. So how does your fictional world work with regard to seasons? Do you have the usual 4 or say 2 winters, 1 summer, 1 spring, 3 autumns or what have you?
Whatever you choose, you need to have thought through why you have the seasons the way you do and to be able to show your reasons, even if you only drip feed this information into your story. Your readers need to be able to "see" your world working for it to seem real. When it seems real, they will be gripped by what you have written. And the setting for your characters (the world itself, its geography, history and politics to name a few examples) adds to that sense of reality.
I stayed with the traditional four seasons as I felt setting up the Fairy Kingdom's government, some of its history, the way the Fairy News Network works and so on were more important things for the background of my novels and stories. So what is the most important things about the world(s) of your stories you need your readers to know?
