The best time to visit Courtallam is during the monsoon season, from June to September, when the waterfalls are at their most impressive. However, the post-monsoon months of October and November also offer pleasant weather and abundant water flow.For those seeking the full natural spectacle, the peak monsoon months are ideal. The heavy rains invigorate the waterfalls, such as Main Falls and Five Falls, making them a truly grand sight. This period is great for travellers who appreciate the lush greenery and the refreshing spray of the falls, despite occasional heavy downpours. It's a particularly good time for those looking for a rejuvenating break amidst nature.Families often find the post-monsoon months, particularly October and November, more comfortable. The rains have subsided, but the waterfalls remain full and powerful. The weather is generally cooler and more settled, allowing for easier exploration of the falls and nearby temples without the intensity of the monsoon.
