The best time to visit Panchgani is during the winter months from November to February when the weather is cool and pleasant. The temperature ranges from 12°C to 25°C (54°F to 77°F), making it comfortable for sightseeing and outdoor activities. The monsoon season (June to September) also brings lush greenery and is a good time to enjoy the waterfalls and the beauty of nature. However, it's important to check the weather conditions and road accessibility during the monsoon season as heavy rainfall can lead to landslides and roadblocks.
