What's the weather like in Gili Islands by month?
Each month classified as peak (best balance of weather and value), shoulder (a step in either direction), or low season.
Why visit Gili Islands during May–Sep?
The optimal time to visit. Calm seas, reliable fast-boat connections from Bali, excellent diving visibility, and near-constant sunshine.
Shoulder season (Apr, Oct) trades a small weather concession for noticeably smaller crowds and softer prices — often the sweet spot for travelers who want flexibility.
Low season (Jan–Mar, Nov–Dec) is when prices fall hardest. Expect weather extremes (heat, humidity, cold, or rain depending on the destination) and reduced hours at some seasonal businesses, but the trade-off can be worth it if budget or solitude matters more than perfect conditions.
What festivals and events happen in Gili Islands?
- RamadanVaries (Islamic calendar — approx. Feb-March in 2026)
The month of fasting observed by the Sasak Muslim community. Some warungs close during daylight hours and alcohol service at local establishments can be restricted. Tourist bars on the Gilis generally remain open but operate differently. The pre-dawn and post-sunset meals (sahur and iftar) create a quiet, respectful atmosphere in village areas.
- Lebaran / Eid al-FitrVaries (end of Ramadan)
The end of Ramadan is the most important holiday in Indonesia. The Gili Islands and Lombok see a surge of domestic Indonesian tourists during the Lebaran holiday week. Accommodation prices rise significantly and ferries and fast boats fill up — book early if your visit falls during Lebaran.
- Indonesian Independence DayAugust 17
National holiday with local celebrations on the islands. Flags, games, and community gatherings in the villages. A good opportunity to witness Sasak community life and join in the celebrations.
- Nyepi — Bali Day of SilenceMarch (Balinese calendar)
Nyepi is Bali's Hindu New Year, observed as a full day of silence. The practical consequence for Gili visitors: Bali's Ngurah Rai International Airport closes for the day and fast boats do not operate on the Bali-Gili route. Do not plan to arrive or depart via Bali on Nyepi day — check the date before booking.

Frequently asked
When is the best time to visit Gili Islands?
The best time to visit Gili Islands is May–Sep. The Gili Islands have a tropical climate with two distinct seasons: a dry season from April to October and a wet season from November to March. These months balance comfortable weather, manageable crowds, and prices that haven't yet hit peak-season highs.
When is the cheapest time to visit Gili Islands?
Low-season months in Gili Islands run Jan–Mar, Nov–Dec. Flights and hotels typically run 20-40% cheaper than peak. The trade-off is weather (which is why these months are off-peak) and some businesses operating shorter hours, especially in smaller seasonal destinations.
What's the weather like in Gili Islands year-round?
Summer averages around 29°C (84°F) and winter averages around 27°C (81°F) in Gili Islands. The Gili Islands have a tropical climate with two distinct seasons: a dry season from April to October and a wet season from November to March. Temperatures are warm year-round, typically 25-32°C, and the sea stays at 27-29°C in all months — making diving and snorkeling comfortable throughout the year. The key variable is not temperature but sea conditions: during the wet season, strong winds and rough seas can cancel fast-boat services from Bali and make some dive sites inaccessible. The dry season brings reliably calm water, excellent visibility for diving (15-25 meters), and near-constant sunshine. Humidity is high in both seasons; even in the dry season, brief morning showers are not unusual. Mosquitoes are present year-round but significantly worse in the wet season — dengue fever is a real risk, particularly from November to February, and DEET-based repellent is strongly recommended.
