Explanation: Kodaikanal, often referred to as the "Princess of Hill Stations," is a popular tourist destination located in the Western Ghats of Tamil Nadu. It is situated at an elevation of about 2,133 meters (7,000 feet) above sea level, making it a cooler alternative to the hot and humid plains during the summer months, including August.
The town is known for its picturesque landscapes, including the Kodai Lake, which is a man-made lake surrounded by lush greenery and is a favorite spot for boating and picnics. Other notable attractions include the Pillar Rocks, which are massive granite formations, and the Bryant Park, which is a beautiful garden with a variety of flora and fauna.
Kodaikanal's climate is one of its most attractive features, especially during the summer. The average temperature in August ranges from 15°C to 25°C (59°F to 77°F), which is significantly cooler than the plains. This makes it an ideal destination for tourists seeking respite from the heat. The town also experiences a pleasant breeze, adding to the overall comfort and appeal.
In contrast, the other options listed are not suitable for the question. Cherrapunjee, located in Meghalaya, is known for its heavy rainfall and is not in Tamil Nadu. Munnar, a popular hill station in Kerala, is also not in Tamil Nadu. Augumbe, a small town in Karnataka, is not a significant tourist destination in Tamil Nadu.
Therefore, Kodaikanal is the correct answer as it is a great place to visit in Tamil Nadu, especially in the month of August, due to its cool climate and scenic beauty.
