Reunion Island in June: weather, whales and things to do in 2026
In June the dry season is fully under way, the first humpback whales arrive and the mountain trails are at their best. It is one of the best windows of the year, just before the July crowds.
June officially marks the start of the humpback whale season (Megaptera novaeangliae). Coming from Antarctica, they migrate up to the warm waters of the Indian Ocean to give birth and nurse their calves. Success rate for trips from Saint-Gilles: 40-50% in early June, 70-80% by late June. Operators must follow the Quiétude whale-watching code of conduct.
In June, the southern-hemisphere winter settles in for goodin Reunion Island. Expect clear skies, steady trade winds, bone-dry trails and the first humpback whales offshore. The sea is cooler (24 °C) but still pleasant in the lagoon. The Hauts (the island's highlands) turn genuinely cool (8-12 °C at night): perfect for hiking, but pack a warm jacket and hat if you are camping.
June has one big advantage: until around 5 July, the French school holidays haven't started yet. Flight and hotel prices stay reasonable, the gîtes (mountain guesthouses) in Mafate are not yet packed, and the whales are starting to arrive. After 5 July, everything changes: peak tourist season, prices up 30-50%, gîtes fully booked.
The trade winds set in, the sea changes mood and the whales arrive.

Things to do in Reunion Island in June
June is the month for the big hikes. On land, the trails are at their very best: a guided Mafate crossing (2-5 days staying in gîtes), an ascent of Piton des Neiges, the Piton de la Fournaise at sunrise and Trou de Fer from Bélouve.
Out at sea, the first humpback whales are here: whale and dolphin watching from Saint-Gilles kicks off its season (a 40-50% success rate early in the month, 70-80% by late June). The catamaran cruise remains a must, with near-daily dolphins. The catamaran leaves from Saint-Gilles harbour, so unless you're staying in town, hire a car for the drive over.
For aerial views, June offers the clearest skies of the year: the helicopter and tandem paragliding in Saint-Leu are at their best. For an adrenaline rush, the Fleur Jaune canyon in Cilaos is in ideal condition too.
