Tide Table Saint John — 2026

📘 About Saint John Tide Forecast

In the northern hemisphere, the coastal area of Saint John (Canada) is positioned at coordinates 45.25° N and 66.06° W. Its tidal pattern is semi-diurnal (two high and two low tides per day), with a mean tidal range of 5.7m and spring tides reaching up to 6.5m. Extreme range demands long anchor chains: boats must allow for several metres of vertical change when mooring. Mariners in semi-diurnal areas benefit from two high-water windows each day to cross shallow bars or enter marinas. Waters along this coast are influenced by events such as El Niño, which can temporarily raise mean sea level.
