No our house is colder in the evening too around the same and I asked this same question here about a year ago.

 

What gets the budgies sick is the sudden change of hot and cold, they will adjust to the weather as winter comes and their feathers will thicken up and they will not molt as frequently.

 

I live in the northern part of the US so we get pretty cold and Pretty was perfectly fine :hap:.
