Scuba Diving Regions in The Marshall Islands
From world-class walls to muck diving havens, discover the unique character of each regional cluster.
Regional Diversity
Diving is possible year-round in the Marshall Islands thanks to warm equatorial water, but the most comfortable and predictable conditions fall in the dry season from December to April, when seas are calm, visibility is at its best and the risk of tropical storms is lowest. The wetter, more humid season from July to October brings higher rainfall and the chance of passing squalls, though the sheltered lagoons of Majuro, Kwajalein and Arno remain diveable between weather systems. Bikini and other remote atoll expeditions are almost exclusively run in the calm dry-season window because of the long ocean crossings involved. Water temperatures hover between 27 and 30 degrees Celsius, making a 3 to 5 mm wetsuit comfortable in every month, and surface conditions are generally settled across the equatorial belt.
Planning Tips
Many regions are seasonally dependent. For The Marshall Islands, the best diving conditions are usually spread across different months depending on the archipelago or coast.
