The short answer
When to go to Coonoor
January to March is the best window: the driest weather, clear mornings and the best chance of seeing Catherine Falls from Dolphin's Nose. April and May are mild with some showers, and May has the Sim's Park fruit show. October and November are the wettest months, with rain above 340 mm in each, so cloud, slides and slow roads are likely. Older travellers should favour January to April and plan viewpoints for mornings.
