Synonym discussion
Sense: noun/1
Spring tide refers to the twice-monthly cycle when the tidal range (the gap between high and low water) is at its maximum. This is distinct from high tide (the daily peak water level) or low tide (the daily low point). A neap tide is the opposite — it occurs between spring tides when the tidal range is smallest. Unlike a tidal surge, which is an unusual rise caused by storms, a spring tide is a predictable astronomical event. For example: 'The spring tide tomorrow will reach 5 metres, while next week's neap tide will only reach 3 metres.'

Etymology
The word 'spring' in 'spring tide' does NOT refer to the season of spring. It comes from the Old English 'springan' meaning 'to leap, rise, or burst forth' — describing how the water seems to spring up higher than usual. 'Tide' comes from Old English 'tīd', meaning 'time' or 'season'. So a spring tide is literally a 'leaping time' of the sea. The term has been used since the 16th century.
