Best Times for Indian Travellers to Visit Asia
Asia's travel seasons vary significantly by destination. Thailand is best visited November through April, avoiding the monsoon season. This aligns well with Indian winter holidays from October to February and travel periods around Diwali and year-end.
Japan has two popular seasons: spring cherry blossom from late March to early May and autumn foliage from October to November. Both are popular with Indian tourists. Summer in Japan is hot and humid.
Singapore and Malaysia have no real seasonal variation as equatorial countries. Any month is suitable, though November and December can have heavier rains.
Bali is popular year-round. The dry season from April to October is most comfortable for beach and outdoor activities.
South Korea is popular in spring for cherry blossoms and autumn for foliage.
