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 Marion Island Tide Forecast
In the southern hemisphere, the coastal area of Marion Island (South Africa) is positioned at coordinates -46.87° S and 37.87° E. Its tidal pattern is semi-diurnal (two high and two low tides per day), with a mean tidal range of 0.4m and spring tides reaching up to 0.7m. Tides here are almost imperceptible, with a range below 0.5 metres, keeping the sea visually calm throughout the day. The semi-diurnal cycle flushes coves frequently, shortening water residence time and maintaining high oxygenation levels. This coast is subject to longshore drift currents that distribute sediment and shape beaches throughout the year. Review the annual 2026 tide guide for Marion Island, constructed with continuous high and low water forecasts measured in metres. In October, Marion Island 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.
