• Synonym満ち干みちひNeutralTagged as an antonym, but the two are not opposites: it is the native word for ebb and flow, matching 「干満」 in meaning; only the register differs.
• Related潮しおNeutralMuch broader: tide, sea water, even an opportunity; it does not specifically name the paired rise and fall that 「干満」 does.
• Related潮合しおあいWrittenWritten and rare: where tidal currents meet or the hour of the tide, also an opportunity; unlike 「干満」 it does not name the ebb-and-flow phenomenon itself.
• Related潮の干満しおのかんまんWrittenA fuller, more explicit way to say 「干満」; the meaning is the same, just stated more plainly.
• Related潮汐ちょうせきFormalFormal scientific term for the tides, focusing on the rise and fall of the sea caused by the gravitational pull of the moon and sun; more technical than 「干満」.

For the tide's ebb and flow use 「干満」, often as 「干満の差」; the native words are 「満ち干」 and 「満ち引き」. In scientific contexts use 「潮汐」. 「潮」 is broader, 「潮の干満」 spells it out, and 「潮合」 is a rare written word for tidal hours or an opportunity.
