September is shoulder season. The east is still dry and the Gathering continues, but Yala's main blocks usually close for part of the month (in 2026 from 14 September to 15 October), so plan safaris at Udawalawe or Minneriya instead.

Sri Lanka has two monsoons, so one coast is usually dry. The map opens on September; tap another month to compare.
