📘 About Iwasaki Tide Forecast

Found at 40.58° N latitude and 139.92° E longitude, Iwasaki serves as a prominent coastal location in Japan. Its tidal pattern is diurnal (one high and one low tide per day), with a mean tidal range of 0.2m and spring tides reaching up to 0.3m. With less than half a metre of variation, water levels here are mostly driven by surface waves and atmospheric pressure changes. On diurnal coasts, flood and ebb currents tend to be more prolonged, lasting nearly 12 consecutive hours in each direction. Waters along this coast are influenced by events such as El Niño, which can temporarily raise mean sea level.
