Morphology
The noun is compositionally built from 'tidal' (relating to the tide) + 'bore' (an upriver tidal wave), so its meaning — a wave caused by the incoming tide — is directly derivable from the constituents. Even though the 'bore' sense is somewhat specialized, a learner who knows that sense will readily infer the combined meaning, making it transparent.
Etymology
The noun tidal bore comes from a simple image: tidal means the sea's tide and bore means a strong wave that pushes up a river. Imagine a wall of water moving against the river's usual flow and surprising people, so the tidal bore means 'a high, often dangerous wave that rushes upstream'.
