🎣 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 Derby Tide Forecast
With geographic coordinates of -17.29° S, 123.61° E, Derby is a key coastal reference in Australia. Its tidal pattern is mixed semi-diurnal (unequal tidal heights across the day), with a mean tidal range of 5.3m and spring tides reaching up to 8.4m. Currents driven by these extreme tides can reach 5 knots or more through narrow passages, making navigation hazardous in adverse conditions. Significant diurnal inequality in mixed tides generates stronger currents when falling from the higher high water to the lower low water. The continental shelf morphology in this area amplifies or attenuates tidal waves arriving from the open ocean. The 2026 tidal bulletin for Derby delivers a thorough schedule of sea level swings with hourly marks for the entire year. In September, Derby is in its spring 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.
