How it's used
Refers specifically to the strength or intensity of a water current rather than just the state of the tide. It is frequently used by people near the coast or those involved in water sports to warn about safety conditions. While it describes the movement of water, it is not used to describe the water level itself.
Examples
The water current is very strong today, don't go into the water.
Related words
Common mistake
Learners often confuse this with 潮漲 or 潮退, which refer to the rising or falling of the tide. Remember that this focuses on the speed and force of the flow, not the height of the water.
