July is peak summer in the Northern Hemisphere. The Red Sea is at its warmest (27-29°C) with glassy conditions, and the Mediterranean is in full swing. Bali and Komodo continue strong mola mola season. The Galapagos are at peak with whale sharks arriving at Darwin and Wolf. In the Caribbean, water hits 29°C — warm enough for a 3mm suit — though late-season hurricane risk begins to build in August. The Similans and Tubbataha remain closed for monsoon. Book European dive trips early.
