Approximately twice a month, around new moon and full moon when the Sun, Moon, and Earth form a line (a configuration known as a syzygy), the tidal force due to the Sun reinforces that due to the Moon. The tide's range is then at its maximum; this is called the spring tide. It is not named after the season, but, like that word, derives from the meaning "jump, burst forth, rise", as in a natural spring.

As spring tides, or king tides as they're sometimes referred to, began to flood homes, the village [of Tebunginako] picked itself up and moved fifty yards inland.

If I slept at all that night, it was only to imagine myself drifting down the river on a strong spring-tide, to the Hulks; a ghostly pirate calling out to me through a speaking-trumpet, as I passed the gibbet-station, that I had better come ashore and be hanged there at once,

The gilt edge of a new moon hung in the sky, and he knew there would be a spring tide in a few hours. It would spill out of the needlegrass like a broth overflowing its bowl.
