Factors Determining Weather in Theni
Geographical Influence on Weather Theni
Theni is located close to the Western Ghats, which have an important influence on its climate. The area’s elevation and closeness to the hills contribute to variations in temperature and rainfall. The windward slopes of the mountains receive greater rainfall through orographic lifting, a process in which moist winds rise, cool, and condense to produce rain.
Key geographical effects on weather in Theni include:
- Hilly regions receive more rainfall than the plains.
- Elevation and forest cover help keep temperatures moderate.
- Humidity levels differ between the plains and hill regions.
These geographical characteristics give Theni a distinctive climate and contribute to the formation of different microclimates across the district.
“The Western Ghats produce distinct microclimates in Theni, resulting in varied weather conditions across the district.”
Monsoon Influence on Weather Theni
India is influenced by two primary monsoon systems, and Theni’s weather is affected mainly by the northeast monsoon, while the southwest monsoon also makes a contribution.
- Southwest Monsoon (June to September): Produces light to moderate rainfall in Theni, particularly across the hilly regions.
- Northeast Monsoon (October to December): Provides the largest share of rainfall in Theni, particularly during October and November.
The northeast monsoon has an important role in replenishing water supplies, supporting agricultural activities, and influencing the everyday lives of people across Theni.
“Northeast monsoon rainfall shapes Theni’s yearly climate cycle while supporting agriculture and regional water resources.”
