🎣 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 Honmoku Tide Forecast
The coordinates for Honmoku (35.43° N, 139.67° E) place this stretch of Japan's coast in the northern hemisphere. Its tidal pattern is semi-diurnal (two high and two low tides per day), with a mean tidal range of 1.1m and spring tides reaching up to 1.7m. With tides reaching up to 1.5m, local fishers typically work around the two hours flanking high tide to benefit from stronger flow. The regularity of semi-diurnal tides — two highs and two lows approximately 6 hours apart — simplifies crossing planning and fishing scheduling. This coast is subject to longshore drift currents that distribute sediment and shape beaches throughout the year. The 2026 tidal bulletin for Honmoku delivers a thorough schedule of sea level swings with hourly marks for the entire year. In September, Honmoku is in its autumn season, a key period for water sports, fishing, diving, and coastal navigation. Predictive output is continuously benchmarked against time series recorded by regional coastal reference stations.
