The short answer
When to go to Itanagar
November to February is the best window: skies are clear, days are mild at around 23 to 28 degrees and rainfall is minimal, with December the driest month. March is still workable. May to September is the monsoon, with monthly rainfall above 450 mm in the peak months, which brings landslides and slippery paths. For older travellers, the winter months are far more comfortable for the hilly sights, though you should carry a light jacket for cool evenings.
