Why is it that a person is more readily to get shocked during the winter than during the summer? Is it because air is drier during the winter and thus the air acts as a better dielectric (closer to vaccuum conditions) and makes air a better capacitor, while during the summer the air is moist and humid and so there is greater impediance and the air is a worse capacitor.

maybe because wearing clothes made of wool?

I disagree with that notion. Because if it is a very cold day and you touch a door knob, you can get shocked.

maybe because you wear heavy shoes with rubber sole

Humidity is indeed important. You tend not to build up as large a voltage as humidity increases.
