Morphology

slack + tide

The meaning is directly derivable from 'slack' (lack of movement, slack/slow current) combined with 'tide' (periodic sea-level/current change) — i.e. a tide with little or no current. This straightforward adjective+noun composition is a common descriptive pattern and would be understandable to a B1 learner who knows both constituent words.

Etymology

Slack tide comes from the simple image of the sea standing still: slack means calm or loose and tide is the sea's rise and fall. Fishermen and sailors used the phrase for the short time when the current stops as the tide turns, so today it means 'the period when the water is relatively still'.
