Explanation:

 The rainy season start at the end of the month of June. The landscape lushes green and fresh. During the season streams and natural springs are replenished. The heavy rains in July and August cause a lot of damage resulting in erosion, floods and landslides. Out of all the state districts, Dharamsala receives the highest rainfall, nearly about 3400 mm. Spiti is the driest area of the state (rainfall below 50mm). The reason is that it is enclosed by high mountains on all sides.
