Marshall Islands Weather

Marshall Islands climate

The Marshall Islands have a tropical oceanic climate with warm temperatures averaging 27-28°C. The archipelago has a distinct rainfall gradient from the drier northern atolls receiving around 1,000mm annually to the wetter southern atolls receiving over 3,500mm.

The atolls' extremely low elevation, averaging just 2 meters above sea level, makes them exceptionally vulnerable to storm surge, wave overwash, and long-term sea level rise.

The northeast trade winds blow consistently from December through April. Drought remains a critical concern for the northern atolls, where extended dry periods can last months.
