The Blues enjoyed an unbeaten month, winning four of their five games.
Birmingham defender Curtis Davies has been named Championship Player of the Month for January.
“Curtis is going through a really good period and in he’s in form,” Hughton said.
“He’s been injury free, which has had a fair amount to do with it, and that’s given him a really good momentum in his game.
“He wants to play every game and we’re benefiting from that.”
