cool cold clowdy days and lot of rain its the danger BUT like here in florida i get rain most every day. I have over 75 adeniums and the key to mine surviving is sun and warm that day or the very next day
The potting mix if correct well draining think your ok.
the adenium i sold you if you put in a good draining mix when you see new leaves your good to go with rain in my option
that trick Mellisa said lets them breath AND lets the soil dry a bit also GREAT tip !!
