Fogging windscreen and windows

[Wozza80]

Hi all, 

I have recently got a 2004 wrx Impreza saloon and now it’s starting to get cold the windscreen and front windows fog/mist up overnight as though air is getting in. Has anyone heard of this before? Wondering if either windscreen seal itself has gone or the window seals on both sides? Any help appreciated. 

many thanks

condensation forms overnight, as this is when the temperature outside is lower
