PVC door won't shut once the sun has been shinning on it for several hours?

My PVC front door faces south and gets alot of sun in the summer time. When the sun has been shinning on it for several hours, if I open it, then it is impossible to close the door completely, so that it locks. I don't know if the door itself is warped or the locks expand because of the sun.

the door will have to be ajusted so there is more clearance on the keeps . some doors are fitted with adjustable hinges which makes this easy .usually only an allan key is req
