Although Nepal has a diverse climatic pattern, the weather is quite predictable in most parts of the country. Unlike the western calendar, Nepali calendars divide the year round weather into six categories of seasons. The higher mountain regions and above observe heavy snow fall during winter. On the other hand, The trans-Himalayan region of Dolpo & Mustang remain untouched by the monsoon rains. Pokhara receives the greatest amount of rainfall in Nepal during the monsoon time.

Summer temperatures in the Terai may reach up to 45 degrees. The temperature generally declines with increasing altitude. The weather remains pleasant in the mountains. However, traveling by road might become dangerous during the monsoon season of heavy downpour. The climate in the Himalayan region remains chilly throughout the year.
