The short answer
When to go to Dambulla
February is the most comfortable month: relatively dry and not yet at the peak of the heat. June to September is also dry but hot, with highs above 33 degrees, so keep to early mornings. October to December are the wettest months, and November in particular brings heavy rain that makes the rock steps slippery. Older travellers should visit the cave temple at opening time and rest through midday. Figures are from Anuradhapura, a dry-zone city to the north, and are a guide for Dambulla.
