Amphidromic Point
Direct answer
Amphidromic Point: An Amphidromic Point is a location of near-zero amplitude for a tidal constituent around which that constituent phase rotates.
An Amphidromic Point is a nodal center of a rotating tidal system.

The story behind Amphidromic Point
Global tide gauges and hydrodynamic theory revealed rotating amphidromic systems organized by basin boundaries and the Coriolis effect.
Amphidromic Point in spiritual tradition
Spiritually, an amphidromic point shows how stillness in one component can sit within a moving ocean system.
The Great Almanac frames Amphidromic Point with educational restraint. Mystical or symbolic language may be meaningful, but it should not be exaggerated into certainty, panic, or permission to ignore ordinary responsibility.
Amphidromic Point in the Bible
This is a factual calendar, astronomy, Earth-science, cultural-history, or observational reference. It can support wonder and practical planning without becoming a claim of fate, spiritual causation, or private revelation.
Amphidromic Point in numerology
Amphidromic Point is not a numerology claim. Any numbers attached to it should retain their ordinary scientific, calendrical, navigational, or historical meaning unless a separate symbolic interpretation is clearly labeled.
Why Amphidromic Point matters
It explains why tide time and range change around ocean basins rather than simply following the Moon westward.
Example in a reading: Cotidal phase lines radiate around an amphidromic center while amplitude grows away from it.
Interpretive caution: Do not interpret a theoretical zero as proof that every observed water-level variation vanishes there.
How Amphidromic Point is used in a reading
Use Amphidromic Point in cotidal charts, ocean-basin dynamics, and tidal-constituent education.
Where interpretation stops
Amphidromic Point is presented as sourced astronomy, calendrical, Earth-science, cultural, or instrument-history reference. Definitions should distinguish measured phenomena from civil convention and historical interpretation, preserve location and time dependencies, and avoid turning factual sky data into a deterministic personal claim.
Sources and editorial method
Research references used for this entry include:
- NOAA Tides and Currents Glossary - Operational definitions for tides, tidal currents, ranges, datums, bores, and amphidromic systems.
The page starts with a direct definition, then separates use, example, caution, spiritual meaning, and historical context. For astrology, occult, demonology, curse, and spiritual warfare terms, the editorial rule is to explain the term without making fear-based, fatalistic, medical, legal, financial, or ritual-instruction claims.
