Tide Table St. John's — 2026

📘 About St. John's Tide Forecast

In the northern hemisphere, the coastal area of St. John's (Canada) is positioned at coordinates 47.56° N and 52.71° W. Its tidal pattern is mixed semi-diurnal (unequal tidal heights across the day), with a mean tidal range of 0.7m and spring tides reaching up to 1m. With tides reaching up to 1.5m, local fishers typically work around the two hours flanking high tide to benefit from stronger flow. Mixed tides blend characteristics of diurnal and semi-diurnal patterns — the morning tide may differ greatly from the afternoon tide in height and current. The continental shelf morphology in this area amplifies or attenuates tidal waves arriving from the open ocean.
