🎣 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 Mera Tide Forecast
Located in Japan, Mera sits at latitude 34.92° North and longitude 139.83° East. Its tidal pattern is mixed semi-diurnal (unequal tidal heights across the day), with a mean tidal range of 1m and spring tides reaching up to 1.5m. Oyster and shellfish farmers exploit the 0.5–1.5m range to alternate aerial exposure and submersion in their culture beds. Experienced mariners on this coast know the second daily high tide is often lower, requiring careful depth checks at bars and channels. Waters along this coast are influenced by events such as El Niño, which can temporarily raise mean sea level. Access the updated 2026 tide table for Mera featuring exact high and low water times, ranges, and coefficients for boating and angling. In September, Mera is in its autumn season, a key period for water sports, fishing, diving, and coastal navigation. Predictive modeling employs updated local oceanic constants, ensuring minimal margin of error in peak tidal timing.
