Mamit experiences a humid subtropical climate (Köppen climate classification *Cwa*), heavily influenced by the Indian monsoon. The weather is generally pleasant and mild compared to the extreme heat of the Indian plains.
Summers (March to May) are moderately warm, with average temperatures ranging from 20°C to 29°C (68°F to 84°F). The monsoon season (June to September) brings intense, torrential rainfall, which is vital for the region's agriculture but frequently triggers landslides and road blockages. High humidity is a constant during these months.
Winters (November to February) are cool and dry, with temperatures dropping to between 11°C and 21°C (52°F to 70°F). Frost is exceedingly rare, and snow is non-existent. The best time to visit Mamit and the nearby Dampa Tiger Reserve is during the cooler, drier months from October to March.
