🎣 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 St Helena Tide Forecast
With geographic coordinates of -15.92° S, 5.72° W, St Helena is a key coastal reference in United Kingdom. Its tidal pattern is semi-diurnal (two high and two low tides per day), with a mean tidal range of 0.6m and spring tides reaching up to 0.8m. The 0.5–1.5m variation exposes sandy flats and shallow reefs at low tide, offering unique opportunities for coastal exploration. The regularity of semi-diurnal tides — two highs and two lows approximately 6 hours apart — simplifies crossing planning and fishing scheduling. This coast is subject to longshore drift currents that distribute sediment and shape beaches throughout the year. Access the updated 2026 tide table for St Helena featuring exact high and low water times, ranges, and coefficients for boating and angling. In October, St Helena is in its spring season, a key period for water sports, fishing, diving, and coastal navigation. MaréAgora calculations use harmonic decomposition calibrated via satellite altimetry and local gauges to ensure high accuracy.
