Average Temperature: 24°C – 34°C
South-West Monsoon brings rainfall from late June, increasing humidity.
Characteristics: Refreshes vegetation and forests; rivers, lakes, and waterfalls become active; crucial for agriculture (paddy, cotton, maize).

Most farming is rain-fed; irrigation depends on rainfall, Kadam River, and local tanks/reservoirs.
Good monsoons directly improve crop yield.
Monsoon rainfall supports forests, wildlife sanctuaries, and waterfalls (Kuntala & Pochera)
Summers may cause water scarcity and dry forest conditions
Winters favor wildlife movement and bird migration
October to February – Best weather
August to September – Best for waterfalls & greenery
April to May – Avoid due to extreme heat
Heat waves during peak summer
Irregular rainfall affecting agriculture
Occasional drought-like conditions
Need for water conservation measures
