The best time to dive in Fiji is from November to April although Fiji is good for diving year-round. Within these months, you can expect wet conditions. From November to April, it is summer in Fiji, and it rains frequently. However, during these months, the diving is at its best due to an influx in plankton. Large marine life such as whales and mantas visit during these months to feast on the tiny marine life. Water temperatures usually range from 82 to 86°F (28 to 30°C). With waters this warm, you’ll only need to pack a 3mm wetsuit. In addition, the best liveaboard deals can be found from November to April as this is low season for Fiji. On the other hand, visibility in Fiji is best from July to December. On a good day, you might see seemingly endless visibility, which in reality reaches 200 feet (60 meters). However, the water is cooler, reaching only 71 to 77°F (22 to 25°C). Finally, surface conditions in Fiji can be slightly choppy from July to September, making the liveaboard journey slightly less pleasant. However, these conditions rarely negatively affect the underwater experience.
