Weather and climate in Makassar (Indonesia)

The climate of Makassar (formerly Ujung Pandang) is tropical, with a rainy season from November to April (due to the northwest monsoon) and a dry season from June to September (due to the southeast monsoon), with May and October as transitional months.
The city is the capital of the province of South Sulawesi and is located on the southern peninsula of the island of Sulawesi (or Celebes), at 5 degrees south latitude. Sulawesi is the southernmost of the four Great Sunda Islands (the other three being Java, Sumatra and Borneo).
The interior of the peninsula is crossed by mountains, which influence the rainfall regime. To the east of Makassar there is a mountainous area, protected in the Bantimurung - Bulusaraung National Park, where the altitude reaches about 1,500 meters (4,900 feet), while to the south-east is mount Moncong Lompobatang, of 2,874 meters (9,429 feet). Nearby is a slightly lower mountain, Bawakaraeng, where the Jeneberang River has its source, which flows into the sea near Makassar, and sometimes floods the city in the wettest period, from December to March.
Indeed, the rains brought by the north-west monsoon are particularly abundant because Makassar is exposed on the western side, while in the period of the south-east monsoon the rains are rare, especially in August and September.
In this season, during the day it is very hot. The highest temperatures are recorded at the end of this period, from August to October, or in November when it does not rain. In 2015, the temperature reached 38.6 °C (101.5 °F) in September and 39 °C (102 °F) in October.
Since we are close to the Equator, the length of day and night is very similar throughout the year. The day lasts 11 hours 50 minutes on June 21, and 12 hours 25 minutes on December 21. The sun reaches the zenith at noon around October 6 and March 7.
Being close to the equator, Makassar (and in general the island of Celebes) is not affected by tropical cyclones.
