🎣 Solunar Table

★★★★★

🌓First Quarter

Major Periods (2h)

19:04 – 21:04Moon overhead

07:26 – 09:26Moon underfoot

Minor Periods (1h)

12:38 – 13:38Moonrise

02:21 – 03:21Moonset

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 Karatsu Tide Forecast

Located in Japan, Karatsu sits at latitude 33.47° North and longitude 129.96° East. 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 1.8m. With tides reaching up to 1.5m, local fishers typically work around the two hours flanking high tide to benefit from stronger flow. Two daily tidal cycles create two current peaks per day, valued by anglers who leverage stronger flow during tidal changes. The continental shelf morphology in this area amplifies or attenuates tidal waves arriving from the open ocean. Review the annual 2026 tide guide for Karatsu, constructed with continuous high and low water forecasts measured in metres. In October, Karatsu 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.
