Contrails

Ok today is a blue bird day about 20F outside and i was looking forward to taking some highflyers photos but theres no contrails around… There are flights going over my house but i can’t find them cus its bright and hurts to look for them thats why i’m looking for contrails… is there a reason why there are not any??? Do conditions have to be right or something?? Sorry if this is a stupid question

First, there are no stupid questions.

Second, yes there have to be specific atmospheric conditions conducive to the formation of contrails for them to occur.
