Optimal Diving Seasons
Peak Seasons
The best months for diving in Kadavu Island are from April to October. This period coincides with the dry season in Fiji, offering calm seas and excellent underwater visibility. The water temperature is also comfortable, ranging from 24°C to 28°C. October is particularly noteworthy as it marks the beginning of the manta ray season, making encounters with these majestic creatures more frequent.
Off-Peak Seasons
Diving during the off-peak seasons, primarily from November to March, has its own set of advantages and drawbacks. On the plus side, this period generally sees fewer tourists, leading to less crowded dive sites. The underwater visibility can vary but is often lower due to increased rainfall. This season also marks the cyclone period, so divers should be prepared for potential weather disruptions. However, the water temperature is warmer, ranging from 26°C to 30°C, which might be more appealing to some divers.
