While November offers a refreshing break from the polluted air of the plains, travellers should be aware of potential risks associated with high-altitude destinations. Snowfall in areas like Rohtang Pass can lead to road closures and disruptions in travel plans. Additionally, temperatures can drop significantly during early mornings and evenings, requiring warm clothing. Visitors should also note that while air quality in Himachal is generally better than in urban areas, some hill towns may experience localised pollution due to traffic or winter smoke.
