🎣 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 Tappi Tide Forecast
The coordinates for Tappi (41.24° N, 140.38° E) place this stretch of Japan's coast in the northern hemisphere. Its tidal pattern is mixed semi-diurnal (unequal tidal heights across the day), with a mean tidal range of 0.3m and spring tides reaching up to 0.5m. Beaches here have very narrow intertidal zones, with only a few metres between high and low water marks. Mixed tides blend characteristics of diurnal and semi-diurnal patterns — the morning tide may differ greatly from the afternoon tide in height and current. Waters along this coast are influenced by events such as El Niño, which can temporarily raise mean sea level. Review the annual 2026 tide guide for Tappi, constructed with continuous high and low water forecasts measured in metres. In September, Tappi is in its autumn season, a key period for water sports, fishing, diving, and coastal navigation. Astronomical tables for this site are processed using tidal harmonic algorithms and adjusted for regional bathymetry.
