Could anybody explain to me if I open two windows in my home, when there isn’t any wind outside, why a cross draft occurs and would there ever be an instance where a cross draft couldnt happen even if its windy?
Thanks so much!

Also keep in mind:
* Any wind hitting a face of the house with a window either had to go through or around the house, whichever is easier. That can cause a disproportionately large draft compared to wind speed depending on the shape of the house.
* Any wind blowing past a sheltered window will create a negative pressure, pulling air out of the house.
The combination of these two effects on opposite sides of the house will pull air through the house very efficiently.
