🎣 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 Okada Tide Forecast
Situated along the coastline of Japan (34.79° N, 139.39° E), Okada lies in the northern hemisphere. Its tidal pattern is mixed semi-diurnal (unequal tidal heights across the day), with a mean tidal range of 0.9m and spring tides reaching up to 1.4m. Surfers here know the waves shift character between high and low tide, even if the tidal range is relatively modest. Significant diurnal inequality in mixed tides generates stronger currents when falling from the higher high water to the lower low water. Data from this station feeds into the global sea-level monitoring network, contributing to long-term change research. The 2026 tidal schedule for Okada provides a full-year calendar of high and low waters alongside predicted sea levels. In September, Okada 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.
