You can pretty much guarantee this subject comes up every year on most car forums. It’s a natural phenomenon unfortunately; moisture in the air inside the car (e.g. from your breath, any damp items in the car) at the end of a journey will turn into condensation on the windows if the windows are colder than the dew point.
As
@adam davies has said, keeping your windows really clean will
help stop moisture ‘sticking’ to the glass, also ensure that the cabin/pollen filter isn’t clogged up and waterlogged. If you’ve got a
garage large enough to accommodate your car but the
garage is currently used as a shed, take the opportunity to have a clear out, take a few trips to the local tip and put your car in the
garage overnight. Check you don’t have anything in the car that might be causing excessive condensation on the windows - damp carpet mats, damp clothing or umbrellas. Also check you don’t have a
problem with water leaks and water finding it’s way into the the interior of the car - check carpets are dry and you don’t have any water in the spare wheel well in the boot. You could also try one of those car dehumidifying bags (

Many people don’t use the air con at this time of year as they don’t need it to cool the car’s interior. However, it can still be used for its dehumidifying effects to
help dry the air in the car’s cabin. I run my air con 24/7 and don’t have any issues with moisture build up). You could also try to equalise the car’s interior temperature to that of the external temperature before the end of your journey by turning the heating down or even drive the last part of the journey with a window slightly open to let the warmer air out.
