🏖️ Recommended Activities

🏊
Sea swimmingExcellent

At low tide the waters tend to be calmer.

📸
Natural PoolsExcellent

Access only within the 2 hours near the lowest tide.

⛵
Nautical ToursGood

Ask the skipper about the conditions.

🎣 Solunar Table

★★★★★
🌓First Quarter

Major Periods (2h)

18:23 – 20:23Moon overhead
06:45 – 08:45Moon underfoot

Minor Periods (1h)

11:43 – 12:43Moonrise
01:51 – 02:51Moonset

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 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. The 2026 tidal schedule for Iwasaki provides a full-year calendar of high and low waters alongside predicted sea levels. In October, Iwasaki is in its autumn season, a key period for water sports, fishing, diving, and coastal navigation. Our oceanographic database syncs historical gauge records to refine harmonic coefficients for this stretch of coastline.
