The best time to visit Nepal is during autumn (September to November) when the weather is clear, skies are blue, and temperatures are moderate, making it perfect for trekking and outdoor activities. Spring (March to May) is also ideal with blooming flowers and mild temperatures. Avoid monsoon season (June to August) due to heavy rains affecting travel and visibility in mountain regions. Winter (December to February) is cold, especially in higher altitudes, but offers clear skies and fewer tourists. Choose your visit based on desired activities and weather preferences for the best experience in Nepal.
