Kathmandu, nestled in the Himalayas, boasts a unique and often unpredictable climate. Understanding its nuances is crucial for any visitor. The city experiences four distinct seasons: spring (March-May), summer (June-August), autumn (September-November), and winter (December-February). Spring offers pleasant temperatures and clear skies, ideal for trekking and sightseeing. Summer brings monsoon rains, often heavy and prolonged, leading to humidity and potential disruptions. Autumn displays crisp, sunny days, perfect for exploring the valley. Winter, however, can be chilly, with temperatures dipping below freezing at night. Altitude plays a significant role; the higher you go, the colder it gets. It’s always advisable to pack layers, as temperatures can fluctuate dramatically throughout the day, even within a single season. Staying updated with the daily forecast is also recommended, especially during the monsoon and winter months. Preparing for varying conditions will ensure a comfortable and enjoyable experience in this vibrant city. Don’t forget to check the weather forecast before embarking on any outdoor activities, particularly treks in the surrounding hills.
