📘 About Rongerik Atoll Tide Forecast

The coordinates for Rongerik Atoll (11.38° N, 167.52° E) place this stretch of Marshall Islands's coast in the northern hemisphere. Its tidal pattern is semi-diurnal (two high and two low tides per day), with a mean tidal range of 1.1m and spring tides reaching up to 1.5m. Rongerik is uninhabited today, but temporarily housed the people of Bikini Atoll between 1946 and 1948 during US nuclear testing. With tides reaching up to 1.5m, local fishers typically work around the two hours flanking high tide to benefit from stronger flow. Mariners in semi-diurnal areas benefit from two high-water windows each day to cross shallow bars or enter marinas. Mean sea level here shows a gradual rising trend linked to global climate change, monitored continuously by local gauges.
