🎣 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 Union Tide Forecast
Found at 47.36° N latitude and 123.10° W longitude, Union serves as a prominent coastal location in United States. Its tidal pattern is semi-diurnal (two high and two low tides per day), with a mean tidal range of 3.3m and spring tides reaching up to 4.2m. Large tides like these require sailing crews and fishing boats to monitor tidal state before entering any shallow harbour. The regularity of semi-diurnal tides — two highs and two lows approximately 6 hours apart — simplifies crossing planning and fishing scheduling. Intense weather events such as storms can create temporary storm surges that add to the astronomical high tide. The 2026 tidal bulletin for Union delivers a thorough schedule of sea level swings with hourly marks for the entire year. In September, Union is in its autumn 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.
