Nepals climate varies with its topography. It ranges from tropical to arctic depending upon the altitude. Nepal has four climatic seasons:
Fall (Sept Nov): Offers excellent weather and tantalizing mountain views.
Spring (March May): Different varieties of wild flowers especially the rhododendrons and excellent Himalayan views make the hillside above 5000 meters a hunting paradise. The temperature is mildly warm in the plains and lower hills, and moderate at higher elevations over 4000 meters.
Winter (Dec Feb): Noted for occasional snowfall only at higher elevations, this season is ideal for travelling or trekking at lower elevations, generally below 3000 meters.
Summer (Jan Aug): Travel is warm and wet with monsoon up till September.
