The Climate and Best Time to Visit
Straddling the equator, Indonesia has a very even temperature throughout the year. High rainfall, tropical heat and high humidity mean that much of the country is covered in tropical rainforest. The dry season runs from May to September. The wet season is from October to April, with rain falling in sudden, short downpours interrupted with bursts of sunshine. Coastal areas experience an average air temperature of 28°C.
However, the country is so vast in area that superb diving can be found all year round in one destination or another since each region has its own distinct micro-climate. We suggest you check out our dive site descriptions of each Indonesian destination for more details on the best season to plan a liveaboard diving trip in each region.
Liveaboard Ports of Departure and How to Get There
Visitors to Indonesia arrive in Jakarta (Java), Denpasar (Bali) or Manado (Sulawesi). Jakarta is well connected with direct flights from most of Asia and Europe. Bali has direct flights from Singapore, Hong Kong, Hawaii and Guam, Kuala Lumpur, Bangkok and Phuket, Tokyo and Taiwan. Manado also has direct flights from Singapore.
You can view which ports the various boats use on their trips in the 'Departures & Prices' section of each boat's webpage. You will also receive full departure details from us during the booking process. There are several domestic airlines that enable you to fly to destinations within the country from the main international airport hubs. You can search domestic flights on Traveloka (select 'Flights' from the menu). Visa and Mastercard are both accepted on the Traveloka website. Domestic airlines include: Lion Air/Wings Air, Garuda, Air Asia, Xpress Air and Sriwijaya Air. You can also make flight reservations directly with these airlines and pay with your debit/credit card. If you experience problems, please ask us to assist.
From 1 September 2023 there is a new electronic customs declaration procedure in effect at all international airports in Indonesia. Visitors can complete the form online: https://ecd.beacukai.go.id/ at least 48 hours before arrival in Indonesia. Alternatively they can complete it on arrival using their mobile device and a QR code which they can scan in the arrivals area, or by using one of the computers available in the customs area.
We recommend guests complete the form before arrival in order to speed up the arrival process and reduce the potential for delays.
Whichever ports your liveaboard uses, it is common practice for the Indonesian dive operators to provide a transfer to the boat from the local airport or hotels (if you overnight beforehand) for your convenience. We recommend you take out insurance to cover diving and travel activities, including trip cancellation. See our insurance programme for a competitive quotation:

Visitor Health
The most common health concerns while on vacation here are stomach complaints from contaminated food, water and ice. These can lead to diarrhoea, dehydration and hepatitis A or E. You should only drink bottled water. Fungal infections are common so you should wear loose clothes, wash frequently, and dry yourself carefully.
Indonesia is malarial but some areas such as Bali are mainly malaria-free. There are not too many mosquitoes at sea so at least you can rest well while you are on your Indonesia liveaboard diving cruise.
You should always seek medical help if you have any health problems while on vacation. It's recommended that you seek medical advice about immunisations at least 6 weeks before travel.
Tourist Security and Safety
While travel anywhere has its risks, we consider Indonesia to be a safe place for liveaboard tourists to travel. You will know from your scuba training that the best way to deal with a potentially risky situation is to make an informed and rational evaluation before taking action. We think that, as long as you are an aware traveller, it poses no greater concerns than most places.
Indonesia is a massive and diverse country. It does have some major internal social problems and conflicts. There are therefore high risk areas. Places like Aceh Province on the northern tip of Sumatra or downtown Jakarta at night, are worth avoiding. But beyond the normal concern of avoiding high risk locations, we feel there is little cause for extra concern.
We have travelled to all the tourist areas described in this section and we have never experienced any threats. We have never had any customers report safety or security concerns. The bombings in 2002, 2003 and 2005 were the actions of a minority and the increased security since then means it has never been safer to visit here. The general feeling you get from a diving trip to Indonesia is one of warmth, hospitality and cultural richness.
