The period between June and September is the rainy season of Mt. Everest. The strong southeast monsoon would always cause awful climate characterized by frequent torrential rain, clouds and mists and suddenly heavy snow or hailstone. The period between November and February is the coldest season of Mt. Everest due to the control of the northwest cold current.
