They always have gradual time jumps during the season. Season 4 was different compared to the first 3 seasons as so many episodes picked up right after the previous one, so there were less time jumps than normal. The first one was actually for the Christmas episode. In the end, the seasons usually end up around spring time in the season finale.

But they are also faking seasonal conditions because from filming I've seen so far, they've brought in trucks to make the streets wet like it was raining, so they definitely don't want it to be too summer-like.
