May is a transitional month across much of the globe, with spring giving way to summer in the Northern Hemisphere. This hot — but not searing — weather is good for outdoor activities and exploring cities, whether you’re in Europe or South Asia. It’s stickier in parts of Southeast Asia and the Indian Subcontinent, but the skies are cloudless and blue.

India

Despite the humidity, May’s heat causes vegetation and smaller waterholes to dry up across the Indian Subcontinent. That means it’s much easier to spot wildlife as animals congregate at the larger, more reliable water sources. To spot elusive tigers, you might visit Pench or take a game drive through Ranthambhore.

Type of heat in India in May: Expect sticky, thick humidity with soaring temperatures of a maximum 108°F.

Average temperature in India in May: 88°F depending on region
