A neap tide leaves the water level low along the rocky shore.

Definition

1. Noun:
   • A tide of minimal range: A "neap tide" is a tide that happens twice a month, shortly after the first and third quarters of the moon, when the difference between high and low water is at its smallest. This occurs when the gravitational pulls of the sun and moon are at right angles to each other, partially canceling each other out.

Usage

• Noun:
  • The neap tide meant the water level at the harbor changed very little throughout the day.
  • Fishermen planned their trip around the neap tide, as the weak currents were safer for small boats.
  • During a neap tide, some areas of the beach that are usually covered remain exposed.

Advanced Usage

• "To be a neap": Used informally to describe the tidal period itself.
  • We're in a neap right now, so the tidal flow is very sluggish.
• "Neap tidal cycle": Refers to the regular, twice-monthly occurrence of these tides.
  • The ecosystem is adapted to the fortnightly neap tidal cycle.
