You'll find that it takes longer in the winter for your bread to get ready, and it'll be faster in the summer. That being said, you can do things to help even out the temperature. You can use warm water on cool days in your starter or in your bread or you can wrap a warm towel around your bowl or starter jar. There's all kinds of tricks, I'd try a few if you are finding your starter or bread are being slow to rise.
