The Terai Plains

The Terai plains, include Chitwan national park jungle Safari, Bardiya National Park situated at a lower altitude, have a subtropical climate characterized by hot summers and mild winters. The temperature here is relatively higher compared to the rest of Nepal, with temperatures soaring above 40°C (104°F) during the summer months.

The Hilly Region

The hilly region, including the Kathmandu Valley, experiences a moderate climate. Summers are warm and humid, while winters can get chilly, especially in higher elevations. The temperature in this region ranges from around 25°C (77°F) in summer to 5°C (41°F) in winter.

Factors Influencing Weather Changes


Altitude plays a crucial role in weather changes in Nepal’s mountains. As one ascends to higher altitudes, the temperature drops significantly. This results in a cooler climate in the mountainous region, even during the summer months.

Monsoon Season

The monsoon season, which typically lasts from June to September, brings heavy rainfall to Nepal. The southern slopes of the mountains receive the highest amount of rainfall, leading to lush greenery and abundant vegetation in these areas.

Wind Patterns

Wind patterns also impact the weather in the Nepal mountains. The Jet Stream, a high-altitude wind current, influences the movement of weather systems. It can result in strong winds and storms, particularly during the winter months.

Impacts on the Local Environment and People

The weather changes in Nepal mountains have significant effects on the local environment and people residing in these regions.

Agriculture and Livelihood

Agriculture is a vital source of livelihood for many communities in the mountains. Weather changes, such as variations in rainfall patterns, can impact crop production and ultimately affect the lives of farmers and their families.
