The air temperature in north Sulawesi stays around 29-32c all year-round. Dry season is from April to November, the best time for blue skies, calm seas and sun, also the best visibility: 20-25m in Bunaken (sometimes 30m+) and 10-15m in Lembeh. Wet or rainy season is from December to March the cooler north-west winds can bring heavier rains and rougher seas in February. The wind and rain can reduce the viz slightly.
Please don’t let the term “rainy season” deter you. We do not get the typical monsoons that they experience in other parts of Asia and it is unusual to have continuous rain during the day. The norm is blue skies and sun in the morning, cloudy in the afternoon, and rain at night. And the rain never spoils a dive!
The average air temperature in the Nusa Lembongan and the Bali area is around 30°c even through the ‘rainy season’. Lembongan’s dry season runs from May to September and this is the best time for the clear skies and calm seas but the water temperature can drop to as low as 18°c in the south during these months. Most of the time the water temperature is around 27°c. Because there are not many rivers around Lembongan, the rains do not overly effect the visibility, with the average being around 25m+ all year round on the north coast and 10m+ all year round on the south coast.
The patches of rain start around the end of November with an hour or so of rain during the day or night and some cloud cover. The ‘rainy reason’ starts in January through to May. Sea conditions in the south during this time can be quite wavy but the north side of the island is protected allowing us, nice comfortable dives all year round.
Malaria – Indonesia is tropical, so malaria cannot be discounted, but we have not experienced any malaria in any of our locations. If western medical advice is to take malaria tablets then this should be followed when visiting this area.
If you are going to take malaria tablets and you will be diving, we do not recommend taking Larium as there is some advice from diving doctors that this is not safe. We suggest you follow your doctor’s advice regarding malaria tablets.
There are some mosquitos, not too many but there are NO other biting insects such as sand-flies. We recommend that you bring some anti-mosquito spray for your arms and legs, and we can provide mosquito coils for your rooms/cottages.
Dengue fever – the odd case of dengue fever has been reported in North Sulawesi, though these tend to be in the villages where rubbish is sometimes not properly cleared.
There are plenty of chemists in Bali and Manado that can provide most drugs. If you require a doctor, you can go at any time of the day to the hospital. If you are not feeling well inform one of our staff and we will help with any arrangements or recommendations. There are also international hospital facilities in both Manado and Bali.
Note that there is no public health service, and everyone has to pay. Be prepared by taking money with you, it is pretty cheap and Rp200-300,000 should be enough for a basic consultation and medicine.
There are always many reports of problems in Indonesia and this is very frustrating for those of us who have lived and worked in this country for many years. There are probably more murders in any major city in the US than the whole of Indonesia but this does not stop embassies from recommending not traveling here.
We believe that it is very safe travelling to Indonesia and in particular the areas in which Two Fish are based. Bunaken Island and Lembeh are are a bit more remote, but they are in the province of North Sulawesi which is 90% Christian and there has been no trouble in this region that has caused any risk to tourists.
With water temperatures between 26-29c, not too much thermal protection is required. We suggest a 3mm shorty, or a 3mm full-suit which also provides protection against any stinging hydroids and a hood for those night dives. If you tend to get cold we would recommend a neoprene vest to go underneath.
In Lembeh from July to Sept the water temp is 25-26oC, and most people need at least a long 3mm or a 5mm.
Most of the time the water temperature is around 27°c. However, during Jul-Oct the water temperatures can drop to 18-20oC on the sites in South Nusa Penida, this is where the manta’s and mola-mola’s are to be found. For these dives you will need a 5mm full-suit, and we have these available for rent.
