Emmm yes and no. The temperature of your back window is falling below the dew point of the air inside the car , hence condensation. When you leave the car the air inside is generally warmer and has absorbed ' excess' water which drops out when its cools below it's dew point.
There are many ways to stop it of varying degrees of impracticality.All have the same general thrust - keep the window temp up or the cabin air dew point ( wetness) down.
Keep it clean - dirt/dust nucleates condensation.
Check the car for leaks , wet carpet, coolant smell etc.
Don't leave wet gear in the car.
Empty the hot air as you park up - door open for a bit.
Leave a window/ sunroof cracked open.
Park the back up against a poorly insulated wall of a house ( keeps frost away as well)
Put a blanket on it.
Stick in in the garage.
Park back to the sun - front will probably mist up instead.
Run a dehumidifier in the car.
Wait 'til summer - my favourite , works every year.
Buy a soft top.
Generally this only lasts a few days when we have high humidity and low overnight temperatures. You won't cure it - Mother Nature wins everytime.
