    Regional Diversity

    Diving in Guam is excellent year-round. The dry season from December to June offers the best visibility and most reliable weather. July to November is the wet season, which can bring more rain and the occasional typhoon, though diving continues between storms. Water temperatures are consistently warm, ranging from 27°C to 29°C throughout the year.
