The weather in Himachal Pradesh in January is typically cold and dry. The daytime temperatures range from around 10°C to 15°C, while nighttime temperatures can drop to below freezing in some areas.

The state is located in the western Himalayas, which means it experiences a high-altitude climate. This results in a much colder temperature than the neighbouring states of Punjab and Haryana.

January is also the winter season in Himachal Pradesh, which means that snowfall is a common occurrence in higher-altitude regions. Popular tourist destinations such as Shimla, Manali, and Kufri may see significant snowfall, which can make travel difficult. However, it also makes for a picturesque winter wonderland and attracts many tourists.

It is important to note that the weather can be unpredictable and can change suddenly. It is always a good idea to check the forecast and be prepared for any weather conditions.

Overall, January is a great time to visit Himachal Pradesh for those who enjoy cold weather and winter sports such as skiing and snowboarding. It is also a great time for photography and sightseeing as the state is covered in snow and is very beautiful.
