I would say drink lots of water. You need a lot more when it’s hot. I was there in May, and I didn’t mind the heat so much, but the thirst had a way of creeping up on me. I don’t think there is any place in Chennai, indoors or outdoors that you won’t enjoy. You must get a sari at Pothy’s in T Nagar. Lot’s of the residential neighborhoods are super charming and filled with cows and goats. I also second the motion you take a day trip to Mahabalipuram.

You will have a lot of fun!
