Lunitidal Interval Basics
- The lunitidal interval is the time between the moon’s transit and the next high tide
- Varies by location due to coastal geography and ocean depth
- Spring tides (higher highs and lower lows) occur during full and new moons
- Neap tides (moderate tides) occur during quarter moons
- Accurate intervals help predict optimal times for navigation and coastal activities

Understanding Lunitidal Intervals
What is a Lunitidal Interval?
The lunitidal interval is the time difference between the moon passing over a location’s meridian (moon transit) and the next high tide. This interval varies by location but remains relatively constant for any specific location.
