The best time to visit Kumily is during the dry season, from October to March, when the weather is most pleasant.
During these months, the temperatures are moderate, typically ranging from 15°C to 25°C (59°F to 77°F), making it comfortable for exploring the outdoors. This period offers clear skies, which are ideal for activities like spice plantation tours, boating on Periyar Lake, and wildlife spotting in the Periyar National Park. It's also the peak tourist season, so you'll find all attractions and services fully operational.
For those who prefer slightly fewer crowds and don't mind occasional light showers, the shoulder months of April to May can also be a good option. While it's warmer, with temperatures reaching up to 30°C (86°F), the pre-monsoon showers can offer a refreshing break and make the landscape particularly lush. However, some outdoor activities might be affected by the heat or rain.
The monsoon season, from June to September, brings heavy rainfall, which can make travel and outdoor activities challenging.
