The question is from the transcript of a podcast:
Mmmm, blueberries. It’s the height of the season, and I’ve been tossing a handful onto cereal, into pancakes or just straight into my mouth.
I don't understand what does the sentence "It's the height of the season" mean.
- What does "it" refer to? Does it indicate "blueberries"?
- What does "the height of the season" mean?
