Best Times to Visit

Gili Trawangan experiences a tropical monsoon climate, characterized by warm temperatures throughout the year. You will find two main seasons: the dry season and the wet season. Each brings different conditions and has distinct aspects for travelers.

Climate patterns throughout the year (temperature, precipitation, humidity)
* Dry Season (May to September): This period has less rainfall, lower humidity, and more sunshine. Temperatures typically range from 26°C to 32°C (79°F to 90°F). Days are generally sunny and bright, with calm sea conditions. This is the most popular time to visit due to the favorable weather for outdoor activities and beach enjoyment. The air feels less humid, making daytime exploration more comfortable.
* Wet Season (October to April): This season brings higher rainfall and humidity. While still warm, daily showers are common, often appearing in the late afternoon or evening. Temperatures remain similar to the dry season, consistently around 26°C to 32°C (79°F to 90°F). Rain showers can be heavy but often pass quickly, leaving clear skies. Humidity levels rise, which some travelers find less comfortable, but the island remains green and lush.

Ideal Timing for Activities

  • Diving & Snorkeling: Best visibility and calmest waters are generally during the dry season, from May to September.
  • Relaxation: Shoulder and low seasons offer a more tranquil experience with fewer people.
  • Surfing: Limited surf breaks are best during the wet season, from November to March.
  • Special Weather: Gili Trawangan typically does not experience hurricanes; the wet season brings increased, but often brief, rainfall.

Visa & Entry Requirements

Visa Types for Indonesia

* Visa Exemption: Citizens of many countries, including ASEAN members, enter Indonesia visa-free for tourism for up to 30 days. This exemption is not extendable. Confirm your country's eligibility before travel.
* Visa on Arrival (VoA): Citizens of over 90 countries (USA, UK, Australia, Canada, most EU nations) obtain a Visa on Arrival for tourism. This visa holds validity for 30 days. You extend it once for an additional 30 days at an immigration office within Indonesia.

It holds validity for up to 60 days and extends twice, each time for an additional 60 days. You apply for this visa in advance at an Indonesian embassy or consulate in your home country, or through a registered visa agent. This option suits travelers planning a more extended visit. For assistance, consider services like IVisa or VisaHQ.

Documentation & Fees

Required Documentation: Your passport must hold validity for at least 6 months from your date of entry into Indonesia. This is a strict rule.

Photos are not generally necessary for a VoA, but useful to have a digital copy for e-VoA or traditional visa applications.
Entry Fees: As of late 2023/early 2024, the Visa on Arrival fee is IDR 500,000 (approximately USD 35). Payment occurs in Indonesian Rupiah (IDR), major foreign currencies, or by credit card at the airport. No special permits are generally necessary for tourism on Gili Trawangan itself. You explore the island freely. However, if you plan to visit specific areas on Lombok, like climbing Mount Rinjani, permits and registered guides are mandatory.

Budgeting & Costs

Currency & Exchange

The local currency is the Indonesian Rupiah (IDR). Rates fluctuate; as of late 2023/early 2024, 1 USD equals around IDR 15,500; 1 EUR equals around IDR 16,500. Check current rates before your trip. ATMs are widely available on Gili Trawangan, notably on the busy east side. These machines accept most major international cards. Money changers also operate on the island, but always verify the exchange rate and count your cash carefully before leaving. Credit cards find acceptance at larger establishments, resorts, and dive shops. Many smaller local warungs, shops, and street food vendors prefer cash payments. Carry small denominations of IDR for convenience.

Money-Saving Strategies

  • Eat at local warungs for cheaper, authentic meals.
  • Rent a bicycle instead of relying on cidomos for every trip.
  • Buy large bottles of water and refill your reusable bottle at refill stations.
  • Haggle respectfully for prices on cidomos, souvenirs, and rentals.

Tipping Culture

Tipping is not traditionally expected in Indonesia for local warungs or street food vendors. However, for higher-end restaurants, dive shops, or tour guides, a tip of 5-10% of the bill or rounding up is appreciated for good service, especially if a service charge is not already included. For cidomo drivers, rounding up the fare or giving a small extra amount is common practice. Good service warrants recognition, but feel no obligation to tip if service falls short.
