The Hill Country: When to Go
The best time to visit the Hill Country is from September to May, when the humidity is at its lowest, with the hot season (February to May) being the optimum period to seek wildlife at Periyar (many water sources dry up at this time and animals are forced to come to the lake). The cooler mountains provide a welcome respite to the sometimes fierce heat in the build-up to the monsoon. Very heavy monsoon rains fall from June to September.
