🎣 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 Sumoto Tide Forecast
In the northern hemisphere, the coastal area of Sumoto (Japan) is positioned at coordinates 34.35° N and 134.90° E. 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. Tides have a moderate range of 0.5 to 1.5 metres, creating gentle currents that influence shore fishing. Mixed tides make planning more complex: the day's two high tides reach different heights, requiring careful study of the tide table before each outing. 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 Sumoto, constructed with continuous high and low water forecasts measured in metres. In September, Sumoto 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.
