Tide Table SAN JUAN — 2026

📘 About SAN JUAN Tide Forecast

Found at 18.46° N latitude and 66.12° W longitude, SAN JUAN serves as a prominent coastal location in Puerto Rico. Its tidal pattern is mixed semi-diurnal (unequal tidal heights across the day), with a mean tidal range of 0.4m and spring tides reaching up to 0.5m. The minimal tidal range protects anchorages from extreme water level changes, facilitating port operations. Mixed tides make planning more complex: the day's two high tides reach different heights, requiring careful study of the tide table before each outing. Waters along this coast are influenced by events such as El Niño, which can temporarily raise mean sea level.
