What you describe is the result of the warmer air inside the building
hitting the colder surface of a cold window, not the reverse.

Condensation generally happens when warm, moisture laden air hits a
cooler service.

When is the last time you saw condensation forming on a mug of hot
coffee on a cold day?



It is relative.

Already stated in subsequent post prior to yours.

If it is warmer on the inside than out, the condensation
will be on the inside of the window. If the reverse is true it would be
on the outside of the window. You can see this when you have a hot humid
day and have the air conditioner very cold.

Read again what I said ... nothing in your quote above changes what I
stated in the least.

If it real cold, what about frost?

Frost has nothing to do with condensation. AAMOF, if the conditions are
right for condensation, you won't normally see "frost":
