Major Periods (2h)
Minor Periods (1h)
Based on the Solunar Theory (John Alden Knight): fish and wildlife tend to feed more during the periods when the moon is overhead or underfoot (major) and at moonrise/moonset (minor). The score considers the lunar phase and the crossing of major periods with the local high tide.

📘 About Nanaoko Tide Forecast
With geographic coordinates of 37.05° N, 136.97° E, Nanaoko is a key coastal reference in Japan. Its tidal pattern is diurnal (one high and one low tide per day), with a mean tidal range of 0.2m and spring tides reaching up to 0.3m. Divers appreciate the predictability of weak tides, which simplifies planning dives on nearby reefs and wrecks. On diurnal coasts, flood and ebb currents tend to be more prolonged, lasting nearly 12 consecutive hours in each direction. Mean sea level here shows a gradual rising trend linked to global climate change, monitored continuously by local gauges. Check the official 2026 tide forecast for Nanaoko here, including detailed monthly schedules, peak times, and daily metric swings. In October, Nanaoko is in its autumn season, a key period for water sports, fishing, diving, and coastal navigation. Our oceanographic database syncs historical gauge records to refine harmonic coefficients for this stretch of coastline.
