Dimapur features a sub-tropical climate (Köppen: *Cwa*), which is markedly different from the cooler, temperate climate of the higher-altitude Naga cities like Kohima.
Summers (April to October) are hot and highly humid, with average maximum temperatures ranging from 32°C to 36°C (90°F to 97°F). This period coincides with the Southwest Monsoon, bringing heavy, persistent rainfall between June and September. The city can experience high humidity levels, making the summer heat feel more intense.
Winters (November to March) are mild, pleasant, and dry. Nighttime temperatures can drop to around 10°C (50°F), while daytime temperatures hover comfortably around 22°C to 26°C. The best time to visit Dimapur is during the winter months, from October to March, when the weather is cool and outdoor exploration is enjoyable.
