What to expect

Reef mantas (M. alfredi) are resident and predictable; oceanic mantas (M. birostris) range widely. Both species visit cleaning stations daily, often early morning. Night dives near lights can trigger spectacular feeding aggregations.

Water conditions in August

Water temperature in Fiji typically ranges 24-29°C. Visibility at Namena Marine Reserve in August is generally good; check local liveaboard or dive operator reports the week of your trip for specific conditions. Soft coral reef, shark dives is the primary dive style in Fiji.

Practical tips

Never touch mantas – the mucus coat protects them from infection. Approach slowly from below and ahead; never chase. A horizontal body position causes far less disturbance than standing upright in the water column.
