🎣 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 Chofu Tide Forecast
With geographic coordinates of 34.01° N, 131.00° E, Chofu is a key coastal reference in Japan. Its tidal pattern is semi-diurnal (two high and two low tides per day), with a mean tidal range of 2.2m and spring tides reaching up to 3.4m. Shellfish gatherers and line fishers exploit these mid-range tides to access reefs and rocky outcrops exposed at low water. The semi-diurnal pattern, with two complete cycles every 24 hours, allows nautical activities to be planned in virtually any shift of the day. Tidal dynamics in this bay or inlet are shaped by the geometry of its entrance, which can amplify or reduce range relative to the open sea. The 2026 tidal bulletin for Chofu delivers a thorough schedule of sea level swings with hourly marks for the entire year. In September, Chofu 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.
