Mold on wood at bottom of door

Hey I just recently noticed some mold starting to develop on the wood at the base of my patio door. I cleaned it and would like to prevent it from happening again. The metal piece gets really cold and water forms on it soaking the weatherstripping and then soaking the wood. I know I can replace the weather stripping but I see this problem happening again and again... Wondering if anyone has any good ideas? My dad suggested varnishing the wood? I was thinking maybe some silicon under the weather stripping to prevent it from getting wet? Any good ideas would be much appreciated. Thanks.

Is the weatherstripping damaged on the bottom of the door? Is it a covered patio? Is the water forming from wiping snowy boots or rain or just condensation from humidity in the house? If from the last, your best bet might be one of those " door pillows" so that the really cold part of the door does not come in contact with the warm moist air. But first I would replace the weatherstripping on the bottom of the door if it is damaged.

Varnish will only help if there is unpainted/sealed wood. Is there any raw wood on the bottom edge of the door? or does the weather stripping completely cover the edge?

Sealing any exposed wood will help prevent the wood from absorbing moisture, other than that the only solution would be to stop the water from forming on the threshold - easier said than done.

The weather stripping doesn't seem damaged. Yes, it is a cover patio. The water is not forming from winter boots and I don't think it's from the humidity in the house. It seems like the water is forming or getting under the weatherstripping on the metal piece outside and then soaking the weatherstripping then getting into the wood. I think I will start with replaceing the weatherstripping, but I was wondering about getting something under the weatherstripping so it doesn't continue to get wet.

Ya there is some raw wood on the other side of the weatherstripping. It just pops on and off under the wood piece. I was thinking if I varnish the piece just to help stop it from getting wet when the weatherstripping gets wet.

I replaced the weatherstripping and it seems to have helped. I guess warm air from the inside was getting through creating moisture under the waetherstripping then soaking it and into the wood. Thanks for all the advice. First time using this forum and it helped out alot.
