Weather of the temple city of Kanchipuram is pleasant enough. Essentially a tropical climate, the temperature here is stable between 280 C and 380 C all through the year. There are occasional rains with an average rainfall being 87cm. Here, you can expect no wild turnaround in the weather's mood.
Traveling to Kanchipuram is highly fulfilling in any of the seasons,
however we recommend you to plan a trip in between September and May,
and the time when the sun is mild and subdued with cool gust of wind to
keep you refreshed. Wear light and easy cotton clothes while you are
here. However, the temple floors may be of some concern for those with
sensitive disposition. They are made of unpolished stone slabs, which
may get overheated during the day, and walking barefoot (no foot gears
allowed) may be slightly discomforting. This is all you need to worry
about Kanchipuram weather.
