It is hot and humid during these months in Tamil Nadu. You should bring light, airy and cotton clothes. The more breathable they are, the better. Also, bring your sunny weather ensembles like umbrella, cap and of course, a towel to wipe off the sweat. For shoes, it's best to use sandals or flip flops. You also need to bring an extra t-shirt in case what you're wearing becomes wet with sweat. Lastly, bring your own water bottle to quench your thirst.
