Outdoor plug and water

How much rain exposure can the plug take?

Mine needs to be out in the weather (no overhang to protect it)

If put so the 2 outlets are facing down towards the ground
can it withstand the water?

The outdoor plug has an IP 64 rating so it is protected from the rain, but not water getting inside of it. I would suggest putting electrical tape around the plug and the things plugged into it as well as the plug and the extension cord(if you’re using one) to keep the water out.
