Question

Overcast skies and damp conditions seem to amplify them the most.

Answer 1

How Easy do you need this explained?

Because sound moves through the air as a wave it’s effected by that air.
So if the wind is blowing towards you, you will get more sound,
If the air is really cold you will get more sound (cold air is more dense)
