The short answer
When to go to Kottayam
The most comfortable window is December to February, when rainfall is low and the air is driest, with November a good shoulder month as the rain tapers. March to May is hot and sticky, with pre-monsoon showers, and June to August brings very heavy rain on most days. For older travellers, the dry months make short outdoor sights and church and temple visits far easier, and the monsoon is better suited to indoor stops and the waterfall.
