Tonga is in the south Pacific Ocean comprising 169 islands, 96 of them inhabited, stretching over a distance of about 800 km (500 miles).
Known as one of the few places in the world where you can dive with humpback whales, these giants pass through to mate and give birth before they leave for their Arctic feeding grounds. In addition to humpback whales, divers can encounter manta rays, eagle rays, many shark species, and other diverse marine life in the area.
The underwater geography is just as diverse as its marine life; with dive sites containing everything from lagoons, protected marine reserves, drop-offs, passes, drift dives, coral gardens and wrecks to enjoy.
Tonga's climate is tropical with temperatures ranging from 25°C - 29°C year-round. December to May is nevertheless considered the warm season with water temperatures around 24°C/75°F, whereas May to December is the cool season with water temperatures around 21°C/69°F.
To see whales the best time is between the months of July and November.
