Jakarta’s Seasonal Weather
Rainy Season (November–April)
From November to April, Jakarta experiences its rainy season with high precipitation and humidity. January and February mark the peak of the rainy season, with average monthly rainfall reaching 300mm, and frequent heavy downpours in the form of squalls. Average temperatures range from 24-31°C, but the high humidity (84%) makes the weather feel significantly hotter. City roads can temporarily flood, so umbrellas and waterproof bags are essential. Indoor activities such as museum visits and shopping mall exploration are recommended during this period.
Early Dry Season (May–June)
From May to June, the dry season begins with rainfall decreasing sharply and clear skies prevailing. Average monthly rainfall drops below 100mm, with average temperatures ranging from 25-33°C. Humidity decreases compared to the rainy season, making outdoor activities more comfortable.
Peak Dry Season (July–September)
From July to September, Jakarta experiences its best travel season with almost no rainfall and the lowest humidity levels. Average monthly precipitation is only 50-80mm, with temperatures stable at 23-32°C. Clear weather persists, offering ideal conditions for city tourism and outdoor activities. However, sunlight is intense, so sunscreen and sunglasses are essential.
Transition to Rainy Season (October–November)
October and November mark the transition from the dry season to rainy season, with increasingly unstable weather. October sees rainfall beginning at approximately 134mm monthly, while November marks the start of the full rainy season with average monthly precipitation around 224mm. Afternoon showers are common, so carrying a portable umbrella is advisable.
Best Time to Visit Jakarta
The best time to visit Jakarta is from July to September during the peak dry season. This period offers minimal rainfall and the lowest humidity, providing optimal weather conditions for outdoor sightseeing and city exploration. With average temperatures stable at 23-32°C, visitors can comfortably enjoy diverse activities including cultural heritage exploration, shopping, and beach activities under clear skies.
May and June are also excellent choices as the early dry season offers minimal rainfall while attracting fewer tourists than the peak July-September season, allowing for a more leisurely travel experience.
The rainy season from November to April features heavy precipitation and high humidity, making outdoor activities uncomfortable. January and February especially should be avoided due to peak rainfall levels.
For budget-conscious travelers and those concerned about crowds, May-June is ideal, while for the best weather conditions, July-September is optimal for visiting Jakarta.
