Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun and the rotation of the Earth.

- All night the thirsty beach has listening lain
With patience dumb,
Counting the slow, sad moments of her pain;
Now morn has come,
And with the morn the punctual tide again.
- Susan Coolidge, Flood-Tide.
- The punctual tide draws up the bay,
With ripple of wave and hiss of spray.
- Susan Coolidge, On the Shore.
- The western tide crept up along the sand,
And o'er and o'er the sand,
And round and round the sand,
As far as eye could see
The rolling mist came down and hid the land:
And never home came she.
- Charles Kingsley, The Sands o' Dee, Stanza 2.
- I saw the long line of the vacant shore,
The sea-weed and the shells upon the sand,
And the brown rocks left bare on every hand,
As if the ebbing tide would flow no more.
- Henry Wadsworth Longfellow, The Tides.
- The tide rises, the tide falls,
The twilight darkens, the curlew calls;
* * * * * *
The little waves, with their soft, white hands,
Efface the footprints in the sands,
And the tide rises, the tide falls.
- Henry Wadsworth Longfellow, The Tide Rises, the Tide Falls.
- Tide flowing is feared, for many a thing,
Great danger to such as be sick, it doth bring;
Sea ebb, by long ebbing, some respite doth give,
And sendeth good comfort, to such as shall live.
- Thomas Tusser, Five Hundred Points of Good Husbandrie, Chapter XIV, Stanza 5.
