He will go straight into Oldham's squad for Saturday's trip to Exeter.
Seasiders boss Ian Holloway believes Nardiello will benefit from his spell at Boundary Park after finding first-team opportunities hard to come by at Bloomfield Road.
Holloway said: "Dan needs to be playing regular first team football at a decent level and letting him go to Oldham will give him that.
"We have a recall after 28 days and we will monitor his progress over the coming weeks."
