The Climate and Best Time to Visit
North Sulawesi enjoys an equatorial climate, which means it's sunny all year round. There are only 2 seasons - the wet season and the dry season.
The wet season usually falls between November and February and is characterised by intermittent downpours during largely sunny periods. Often the rain does not last long and dries up seemingly instantly. During this period, the Celebes Sea's surface becomes choppier. The usual temperature range is from 23°C to 31°C, on very hot days it may rise up to 33°C. It is cooler in the mountainous regions. The weather is more changeable from December to March but very rarely would the time of year interfere with the Manado diving schedule.
Bunaken experiences peak crowds in July and August, when dive resorts often sell out months in advance. While diving remains good during this period, warmer waters increase plankton, reducing visibility. For optimal conditions with fewer crowds, visit Bunaken between March and early November. Note that whale and dolphin sightings are most frequent in July-August. Water temperatures stay consistently warm (27-30°C) year-round with stable visibility.
The Lembeh Strait is good for visit all year round. Water temperatures hit a high of 29°C at year end, and a low of 25°C in July; visibility variations are not such an issue here. Many say July has the greatest number of critters, but a keen-eyed scuba diver will find all the main critter attractions here at any time of the year.
How to Get There
Manado is in the far north east of the island and is the main city of the North Sulawesi. It is the point of entry for most visitors, particularly those who are resort diving in Bunaken and the Lembeh Strait. The backdrop to this small city is row upon row of rising green peaks and it sits facing the volcanic island of Manado Tua, Bunaken and Siladen islands.
Sam Ratulangi International Airport in Manado has a regular international flight service to/from Singapore with Silk Air. There are also flights from Jakarta and Bali with domestic airlines, including Lion Air/Wings Air, Garuda and Air Asia. You should be able to book direct online with them and pay with your debit/credit card. If you experience problems, please ask us for help.
To dive at Bunaken you will stay in a diving resort around Manado (land transfer of up to 30 minutes) or on the island of Bunaken itself, a 45 minute boat ride from the city. The Lembeh dive resorts located on the mainland are around 1 hour by road from Manado. Those based on Lembeh island itself involve an additional short boat transfer of between 5 and 15 minutes.
