The right winger, who joined Carlisle on a 2 year contract in the summer, has made 23 appearances for the Cumbrians so far this season, scoring two goals along the way.
Raphael Nade in action
His last run out for the Blues was in the 4-0 home win over Bury at the start of January, when he came on to replace Karl Hawley, but his appearances have been limited in the first team recently.
Paul Simpson told us : "this will be a good move for him because it will get him first team football, keep him sharp and keep his fitness levels right up there. He has been itching to get involved, he wants to be playing, so this will benefit him, Weymouth and us. He'll go down there for a month, hopefully play plenty of games and be involved with a team that is doing things right and pushing for promotion to the Conference."
Nade goes straight in to the Weymouth squad for the top versus bottom clash against Carshalton Athletic on Saturday.
