🎣 Solunar Table
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 Ayukawa Tide Forecast
With geographic coordinates of 38.30° N, 141.51° E, Ayukawa is a key coastal reference in Japan. Its tidal pattern is mixed semi-diurnal (unequal tidal heights across the day), with a mean tidal range of 1m and spring tides reaching up to 1.4m. Oyster and shellfish farmers exploit the 0.5–1.5m range to alternate aerial exposure and submersion in their culture beds. Experienced mariners on this coast know the second daily high tide is often lower, requiring careful depth checks at bars and channels. Intense weather events such as storms can create temporary storm surges that add to the astronomical high tide. Track tidal behavior at Ayukawa throughout 2026 using our comprehensive table with daily high and low water timestamps. In October, Ayukawa is in its autumn season, a key period for water sports, fishing, diving, and coastal navigation. Reported times and heights derive from fundamental harmonic component analysis (M2, S2, K1, O1) applied to these coordinates.
