Suppose you want to plan a trip to the state during the offseason. In that case, the monsoon months from July to September are ideal, provided you are okay with the possible delays in journeys due to roadblocks and heavy rainfalls, which may prevent you from covering a few attractions.

Traveling in the monsoon is not for everyone. Still, suppose you can withstand the rains and the accompanying inconvenience.

In that case, you will be rewarded with the stunning lush green landscapes filled with flowing rivers, roaring waterfalls, and splendid panoramic views of the landscapes everywhere.

During the monsoon season in Arunachal Pradesh, the temperatures vary between 10°C to 20°C, which means monsoons are cold.

The rains are inconsistent but mostly heavy, sometimes lasting for many hours, which suddenly brings life to a halt, an important thing to consider if you wish to travel to Arunachal during the monsoons.

Do not miss enjoying the splendour of the Nuranang Falls and Bap Teng Kang Falls in full vigour as they create a magical landscape surrounded by green mountains.


If your idea for the trip is to admire the rich and diverse wildlife and flora, the best time to visit Arunachal Pradesh is the winter season, which lasts from late October to March.

But note that winter is not for everyone, primarily if you are not used to or exposed to extreme temperatures in the high altitudes before. So if you plan to travel to Arunachal in winter, you will need to be well prepared.

The mercury levels begin to drop by the end of November, with the temperature dropping below freezing points by December. The snow envelopes the slopes, hills, and roads, kickstarting the winter season officially.

Winter is also the best time to visit Arunachal Pradesh to ski amidst the rugged mountains with fewer tourists. Many areas are open for skiing around the major towns. The temperature ranges between 5°C and -5 °C during other winter months in the state.

These being the coldest months, it may sometimes be challenging to move around due to snow blockades, especially making travel difficult during January and February. So you may miss a few spots if you are here during these months.
