The daytime temperatures at lower altitudes range from 5 ̊C (41 ̊F) to 10 ̊C (50 ̊F), but at higher altitudes, it is not unusual for the mercury to drop below freezing point, especially during the night. The sky remains clear and offers much of a view of mountains. However, as the trekkers climb 4000 meters, the cold air is more evident. By the end of this month, there is a chance that snow will fall, especially in higher altitudes.
Even though it’s much colder this month, many trekkers still prefer to come here because of stable climatic conditions plus clear skies. Hence, fewer hikers than in October are encountered, which makes trekking less noisy.
