The short answer
When to go to Siliguri
The best months are November to February: dry, mild and often clear enough to see snow peaks on the horizon, which suits the monasteries, the sanctuary and the Teesta valley. March and April are warm but workable, while June to September brings very heavy rain and a real risk of landslides on the hill roads. For older travellers, the winter months also make the long airport and station transfers easier, though mornings can be hazy and cool on the road north.
