Diving Conditions in April

What to expect underwater this month, from water temperature and visibility to marine life activity and seasonal patterns.

April is a transition month. The Coral Triangle is in full bloom with excellent conditions across Raja Ampat, Komodo, and the Philippines. The Maldives sees its last great weeks before the southwest monsoon shifts in May. In the Atlantic, the Azores begin their pelagic season, and the Red Sea is superb with 24-26°C water. Tubbataha reaches the end of its open season. Caribbean water warms toward 27-28°C. This is a smart month for budget-conscious divers — many destinations drop from peak pricing.
