Nestled in the lap of the Himalayas, Sikkim enjoys salubrious weather all through the year. However, the best time to visit Sikkim falls between March to June and October to December.
Summers are blissful as the temperatures are in the lower range (24°C to 45°C), making Sikkim a pleasant escape from the heat and hustle-bustle of the plains and towns. Monsoon is a sheer thrill of nature and is generally avoided. Winter comes, and snow blankets the state and the mountains with average temperatures ranging from 10°C to 27°C. To make plans for a holiday in Sikkim, peruse the weather details in Sikkim.
Summer: April to June
The ideal season to plan a trip to North East India, especially Sikkim, is summer. Temperatures lie between 5-25°C welcoming the summer sun and cool winds. The Tsomgo Lake and the locale in the higher mountains become accessible for visitors.
With summer comes the season of blooming flowers. One such delight is the Yumthang Valley, called the “Valley of Flowers”. The entire valley transforms with many flowers such as poppies, irises, primulas, and mostly rhododendrons. A trek through the Singba Rhododendron Sanctuary is perfect to bask in the bliss of summer. Othertreks in Sikkim are also thrilling as one witness and explore the Himalayan region. Summer in Sikkim also makes camping enjoyable.
The moderate temperatures offer the ideal opportunity to go river rafting at the Teesta River. Furthermore, it offers the chance to try out white water rafting. In addition, pilgrimage is also thriving during summers in Sikkim. There are two hundred Buddhist monasteries, of which a visit to the Rumtek and Pemayangtse monasteries is to be included in a trip to Sikkim.

Rain clouds and rain showers arrive in Sikkim by July, making it a good time to visit Sikkim, only if you do not mind getting wet. With its tea gardens and Kanchenjunga Mountain in the backdrop, the Temi Estate is a beauty to enjoy the season. The Pang Lhabsol festival held around August or September has celebrations with dances performed wearing colorful masks and costumes. Head to the Pemayangtse Monastery to attend the fiesta.
