Understanding Bali Weather Patterns in December
Bali’s tropical climate is characterized by two main seasons: the wet season, which runs from October to April, and the dry season, which lasts from May to September. However, December is a unique month in Bali’s weather calendar, marked by distinct patterns shaped by the Indian Ocean Dipole (IOD) and the El Niño-Southern Oscillation (ENSO).
The Role of the Indian Ocean Dipole (IOD)
The Indian Ocean Dipole (IOD) is a climate phenomenon that affects the Indian Ocean’s temperature gradients. When the IOD is in a positive phase, the eastern part of the Indian Ocean cools more than the western part, leading to changes in rainfall patterns across Australia and Indonesia. In Bali, a positive IOD phase typically results in increased rainfall during the winter months, including December. This is because the cooler water temperatures in the eastern Indian Ocean lead to the development of stronger rainfall events, particularly during the late summer and early autumn months. As a result, December can experience moderate to heavy rainfall, with some parts of the island receiving up to 200 mm of precipitation.
The Impact of the El Niño-Southern Oscillation (ENSO)
The El Niño-Southern Oscillation (ENSO) is a natural climate cycle that affects the Pacific Ocean’s surface temperature. During El Niño events, the eastern Pacific Ocean warms more than usual, while during La Niña events, the eastern Pacific cools more than usual. In Bali, El Niño events typically result in dry conditions, while La Niña events lead to wet conditions. During the 2015-2016 El Niño event, Bali experienced a significantly drier-than-normal December, with some parts of the island receiving less than 50 mm of rainfall. Conversely, during the 1997-1998 La Niña event, Bali received above-average rainfall in December, with some areas receiving over 300 mm of precipitation.
Past Weather Patterns in Bali during December
Bali’s weather patterns in December can vary significantly from year to year, depending on the IOD and ENSO phases. Here are a few examples of past weather patterns in Bali during the month of December:
* 2015-2016: A dry December month, with some parts of the island receiving less than 50 mm of rainfall.
* 1997-1998: A wet December month, with some areas receiving over 300 mm of precipitation.
* 2009-2010: A moderate December month, with some parts of the island experiencing heavy rainfall events.
* 2019-2020: A dry December month, with some parts of the island receiving less than 100 mm of rainfall.
Average Temperature and Humidity in Bali during December
As the holiday season approaches, visitors to Bali can expect a pleasant winter climate, with average temperatures and humidity levels that make the island an attractive destination. December is characterized by a dry season in Bali, resulting in a relatively low humidity level of around 60-70%. This dry air, combined with a temperature range of 20-25°C (68-77°F), creates an ideal environment for various outdoor activities.
Temperature Range in Bali during December

The temperature differential between day and night is relatively small, making it an excellent time to engage in various outdoor pursuits.
Humidity’s Effect on Perceived Temperature
The average relative humidity in Bali during December hovers around 60-70%. While this might seem relatively high, the dry air in the region counteracts the effects of humidity, resulting in a relatively comfortable and perceived temperature. This dry air allows for better air circulation, further reducing the perception of heat. In other words, the temperature feels more pleasant than it actually is.
Comparison of Temperature and Humidity Between Northern and Southern Regions
Bali’s climate varies significantly between the northern and southern regions. Generally, the southern region experiences a slightly cooler temperature than the northern region, with an average temperature range of 21-24°C (70-75°F) in the south and 22-25°C (72-77°F) in the north. The relative humidity also differs, with the south recording an average of 55-65%, and the north experiencing an average of 60-70%.

Rainfall and Sunshine Duration in Bali during December
As the festive season approaches, travelers flock to Bali to enjoy its tropical paradise. However, December marks the tail-end of the wet season in Bali, characterized by increased rainfall and humidity. This period is crucial in understanding the island’s weather patterns, which can greatly impact your travel plans.
The Indian Ocean Dipole (IOD) plays a significant role in shaping Bali’s rainfall patterns. When the IOD is in its positive phase, it tends to enhance the rainfall in the eastern regions of Indonesia, including Bali. On the other hand, a negative IOD phase leads to a decrease in rainfall. This correlation is critical in understanding the rainfall patterns in Bali, especially during December.
The Impact of ENSO on Rainfall in Bali during December, Bali weather in dec
The El Niño-Southern Oscillation (ENSO) phenomenon also has a significant impact on Bali’s rainfall during December. During El Niño events, the rainfall in Bali tends to decrease, while La Niña events lead to an increase in rainfall. This is due to the changes in atmospheric pressure and wind patterns that occur during these events. For instance, El Niño events tend to suppress the rainfall over Indonesia, resulting in a dry season.
Typical Rainfall Pattern in Southern and Northern Bali
Bali is an island divided into three main regions: South, Central, and North. Each region experiences a unique rainfall pattern due to its topography and geographical location. The South is generally considered drier than the North, with the rainiest months typically occurring in the first half of the year.
