In general, no. But it depends on how cold it is outside, how wll the
windows insulate, and the temp and humidity inside. Usually this happens
if the humidity inside is too high. The colder it gets outside, the lower
you want the humidity inside. No more than 50% if it's moderate out,
going down to maybe 25% if it's 10F outside. You can find charts online.
Also this happens in bathrooms, kitchens, more frequently, because humidity
is higher there. If it happens in spots like that after a bath, etc,
no big deal. It should not be happening in most of the house.

Maybe I spent too much time in computer room design but you never want
the RH below 50%. Bad things start happening to your electronics.

Depends on what you have. Single or double pane? Storm windows? Metal
frames? Frost on the glass or frame?

If you live in a cold climate you should have a good double pane window
and you will never see condensation.

What do you have? What state are you in?

It is if the humidity indoors is too high

Even with triple glazed you can get condensation if you have 60+% RH
and it's -30 out. Mabee even a bit of frost or ice

Kept my house at 40% to 50% and we had temperatures to about -5 with no
problems. My first house did though with old windows. Of course, the
OP asked a question and never returned.

Now you have to get used to the condensation on the outside of the
windows. ;-)

Not as much with double or triple pane glass windows. Having a well
insulated window and higher humidity in the home won't produce as much
moisture/condensation than with the same humidity and lower insulated glass.

It's all about temperature, relative humidity and dew point.

Any interior surface of the building that drops below dew point will cause water to condense.

It still all boils down to humidity.

Actually, to dew point and glass temperature - but the dew point is
STILL relative humidity. If the humidity is low enough you won't get
condensation on a single pane window at -40.

I agree. I was implying in a higher humidity home, there would be less
or no condensation on a double or triple pane glass opposed to a single
pane. But overall, with low humidity, it won't show up as you stated.
