难怪 and 怪不得 both mean 'no wonder' and are essentially interchangeable, though 怪不得 feels slightly more conversational and northern. The literal logic is beautiful; 难怪 means 'hard to blame' and 怪不得 means 'can't be blamed,' both capturing the moment you realize why something happened and it all clicks. Place it at the start of your realization: 难怪他今天不来,原来生病了 ('No wonder he didn't come today; turns out he's sick'). Native speakers often pair it with 原来 (yuán lái, 'turns out') for the classic aha-moment structure.
