The Climate in Indonesia

The country has a typical equatorial climate and has two seasons, the rainy season between November to March, and the dry season from April and October. The primary variable in the country’s climate is rainfall. The regions relative humidity is from 70 to 90%. Winds are moderate, with monsoons commonly blustering from the south and east is experienced between June to September and from northwest in December to March.

Regional temperature variant is attributed to elevation rather than latitude. Temperatures are highest along the coast, where the mean yearly temperature in the lowlands is around 30°C, and is noticeably lower in the mountains. Only the Maoke Mountains of Papua are high enough to experience snow. The periodic differences of temperature in Jakarta is not less than 5 times as large as the difference involving the high and low temperatures (January and July); on an extremely hot day in Jakarta the temperature might reach almost 38°C, while in particular cool day it may drop to around 8°C. Typhoons and thunderstorms pose short chance to seamen in Indonesia waters; the major risk occurs from swift currents in canalizes, suchlike as the Sape and Lombok straits.

The recommended wearable is warmer clothes for cool evenings and highland areas. Slacks or trouser and shirts are mostly considered but jackets and tie are required when making official calls or formal occasions. And it is not appropriate to wear shorts and halter tops to any place except on the beach or around sports facilities.
