Morphology

hit + like + a + tidal + wave

The phrase is a simple simile: 'hit' (strike/affect) compared 'like' a 'tidal wave' (a sudden, massive surge), so the overall meaning of a sudden overwhelming impact is directly inferable from the constituent words. This metaphorical image is transparent and cross-linguistically common, so a B1 learner who knows the parts would readily understand the intended sense.

Etymology

Hit like a tidal wave comes from the image of a huge tidal wave suddenly hitting the shore and sweeping everything away. That's why we use it for something that arrives 'sudden and overwhelming' and changes people or plans quickly.
