The best time to visit Kathmandu is from Late September to December because of the views of pristine glaciers and local festivals. During these months, the place remains dry and suitable for exploration and trekking. The temperature in October in Nepal ranges from 26 degrees Celsius to 14 degrees Celsius. Another good time to visit Kathmandu is in March and April as the temperature steadily rises and spring steps in. During this season, rhododendrons bloom, spreading across the whole valley, giving it a beautiful, mesmerising look.
