20C / 68 F is OK for day temperatures for Phals. I recall Italy has fairly good humidity. I don't think Italy is too hot for Phals in summer outside. Your biggest concern would be night temperatures. What are night temperatures now?
Watching for outdoor pests is always a concern.
You might consider editing your profile flag. It is set to Philippines. If you didn't say Italy we might have given you advice for the wrong place.
