The best time to visit Kollegal is generally from October to March, when the weather is most pleasant.
During these months, the temperatures are moderate, typically ranging from 15°C to 30°C, making it comfortable for exploring the outdoors and engaging in activities. The monsoon season, which runs from June to September, brings heavy rainfall, which can make travel and sightseeing less convenient. The summer months of April and May can be quite hot, with temperatures often exceeding 35°C.
For those planning to visit the nearby wildlife sanctuaries or participate in outdoor adventures like trekking, the cooler, drier period between October and March is ideal.
