The best time to go to Kwajalein is during the dry season, which typically runs from December to April.
During these months, you'll experience consistently sunny days and lower humidity, making it ideal for outdoor activities like snorkelling, diving, and exploring the atoll. The sea conditions are generally calmer, offering better visibility for underwater adventures. This period also avoids the peak of the tropical storm season, ensuring a more settled and enjoyable visit.
For those planning water-based activities, this dry period is particularly beneficial.
