Traveller notes on Nusa Penida in September
Other months in Nusa Penida
Nusa Penida's forum places August in the middle of the dry season, low humidity and probably one of the best windows weather-wise. Regulars flag the Bali-Lombok strait's wind as the real factor to watch here specifically — when it picks up, boat crossings and dive conditions can turn choppy — and recommend a jacket or shawl for cooler nights in the island's hillier spots.
