How it works
按说 states what ought to be the case by ordinary reasoning, and almost always sets up a "but" that reports what actually happened. Without that contrast it sounds unfinished.
Examples
按说他早该到了,可是还没来。
Ànshuō tā zǎo gāi dào le, kěshì hái méi lái.
By rights he should have arrived long ago, but he still isn't here.
按说这个季节不会下雪。
Ànshuō zhège jìjié bú huì xià xuě.
Normally it wouldn't snow this time of year.
