A standing wave that oscillates in a lake, bay, or other enclosed body of water, often caused by wind or seismic activity.
Any phenomenon involving periodic oscillation, sometimes used metaphorically in fields like economics or physics to describe regular fluctuations.
Linguistics
Semantic Notes
The term is highly specific to physical geography, hydrology, and oceanography. Its use outside these fields is rare and metaphorical.

Examples
By Part of Speech
verb

Examples
By CEFR Level
- Very large waves in a lake can be dangerous.
- Strong winds can cause the water in a lake to move from one end to the other.
- Scientists measured the unusual wave activity, known as a seiche, in the enclosed bay.

Learning
Memory Aids
Mnemonic
Think: A 'SAY' in the lake. A strong wind might 'SAY' (seiche) 'Shh!' as it pushes the water back and forth.
Conceptual Metaphor
WATER IS A SLOSHING BATH: A seiche is like the water sloshing rhythmically in a bathtub after a sudden movement.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'сейш' (seance/spiritualist meeting). 'Seiche' is a scientific term, not related to the occult.
- Avoid direct phonetic translation to 'сейч' (seych). The correct Russian equivalent in scientific contexts is 'сейша' (seysha).
Common Mistakes
- Mispronouncing it as /siːtʃ/ (like 'beach').
- Using it to describe tidal waves or tsunamis, which are progressive, not standing waves.
- Misspelling as 'sieche'.

No. A tsunami is a series of traveling ocean waves caused by an underwater disturbance. A seiche is a standing wave that oscillates in an enclosed or semi-enclosed body of water, often triggered by wind, seismic waves, or atmospheric pressure changes.
Yes, if it is large enough. It often appears as a rhythmic rising and falling of the water level along a shore, or objects like docks moving up and down without progressing forward.
No. It is a highly specialized scientific term. Most native English speakers would not know it unless they have studied geography, geology, or oceanography.
It is borrowed from Swiss French, specifically from the Franco-Provençal word meaning 'to sway back and forth,' originally describing the phenomenon in Lake Geneva.
