Before we get stuck into the details, here’s an overview of Bali’s temperatures and rainfall by month:

Bali weather and climate

According to the Köppen-Geiger climate classification, Bali has a tropical climate, with regional variations across the island. This means Bali has warm temperatures year-round, averaging between 20°C and 32°C, with consistently high humidity above 75%.

Bali experiences two main seasons: the wet season (November to April), which brings heavy monsoonal rain, and the dry season (May to October), which is slightly cooler, less humid, and generally drier.

While this is the typical weather pattern for Bali, larger climate systems like El Niño and La Niña can influence conditions year to year, sometimes shifting the start or end of each season.

Long-term climate change has also contributed to a gradual increase of Bali’s average temperatures over the last few decades.  

Bali can also experience occasional extreme weather during the wet season, including tropical storms, high winds and, rarely, cyclones. While these events are uncommon, they have the potential to cause significant damage to the island's infrastructure and could impact and disrupt your travel plans. It’s a good idea to check weather forecasts and reports when visiting during the wet season.

Bali seasons

• The wet season (November to April), which brings heavier rainfall and higher humidity;
• The dry season (May to October), which is typically cooler, less humid and known for clear skies and sunshine. 

The average temperature in both seasons stays fairly consistent, ranging from 20°C and 32°C, but humidity and rainfall is typically higher during the wet season. In recent years, weather patterns like El Niño and La Niña have shifted the timing and intensity of Bali’s seasons.

Bali weather & climate by region

Thanks to its tropical climate, Bali experiences year-round warm weather, high humidity, and consistent rainfall – however the weather varies by region. The island’s mountains, valleys and coastline each have their own weather characteristics and conditions – for example the mountainous areas tend to be cooler and experience more rainfall than the coastal regions. The coast is also often more humid than central Bali. 

Here's some more detail on what to expect from Bali’s climate in the coastal, central, and mountainous regions to help you plan your trip.

What is the weather like in coastal Bali?

Bali’s coastal region – made up of the popular beaches like Kuta, Seminyak, Nusa Dua and Sanur - is characterised by high humidity, hot temperatures, and rainfall throughout the year. The tropical weather of Bali’s coast is often hotter and more humid than central Bali and the mountainous region, with average temperatures typically ranging between 24°C and 32°C. Rainfall is often heaviest and more frequent during the wet season (November to April), particularly in January. The average humidity in Bali’s coastal region is 80 – 85% and is often higher during the wet season compared to the dry season.  July and August are typically the best months to visit Bali’s beaches, with an average maximum temperature of 29 – 30°C, humidity of 75 – 80% and minimal rainfall. Make sure to pack your swimwear, sandals and lightweight beach clothes when travelling to Bali’s coast – and don’t forget a small umbrella or poncho, too.

What is the weather like in Bali's mountains?

Due to a higher elevation compared to the coast, Bali’s lush mountainous, including Mount Batur and Mount Agung, are known to experience cooler and less humid conditions than the coastal region, and tend to receive increased rainfall, too. Nighttime temperatures are often cooler in the mountainous regions, too. Temperatures vary significantly according to elevation, so you should expect it to get colder as you reach the peak of Bali’s mountains. 

December to February tend to be the wettest months to visit Mount Batur and Mount Agung. For the best chances of a clear day (and less muddy route), plan your trip between May and September when you have a better chance of a clearer day (and less muddy route!) If heading to the mountain areas of Bali, make sure to wear warm layers and be prepared for rain. It’s highly recommended to do the trek as part of a guided tour, just make sure to check the weather forecast before your trek!

Mount Batur weather

Mount Batur is one of Bali's most active volcanoes, located in the northeast part of the island. It stands at an elevation of 1,717 metres above sea level and is a popular hiking destination. The average temperature at the summit of Mount Batur is around 15°C, making it significantly cooler than the surrounding lowlands. Temperatures can drop to as low as 10°C at night, so it's important to bring warm clothing if you plan on hiking to the summit. During the day it becomes very hot - with an average yearly maximum temperature of 29°C at Mount Batur’s base.

Mount Batur receives around 1,700 – 2,500 mm of rainfall annually, with the majority falling during the wet season. During this period, the average monthly rainfall is between 200 mm and 350 mm, which makes hiking conditions challenging. The dry season runs from May to October, with lower rainfall and more sunny days. However, even during the dry season, there can still be occasional rain showers, so it's important to be prepared with rain gear.

Mount Agung weather

Mount Agung is Bali's highest volcano, standing at an elevation of 3,031 metres above sea level. The average temperature at the summit of Mount Agung is around 10°C, making it significantly cooler than the surrounding lowlands. At night, temperatures at the peak can drop to as low as 5°C, so warm clothing is necessary for those planning to hike to the summit. During the day Mount Agung can be quite hot, with an annual average maximum temperature of 30°C at Agung’s base – so bring layered clothing.

On average, Mount Agung receives around 2,500 – 2,900 mm of rainfall per year. The wettest months are in the rainy season from November to April, when heavy rain often makes hiking difficult. It’s best to come during the dry season (May to October) for safety and an enjoyable hike. However, even during the dry season, there can still be occasional rain showers, so it's important to be prepared with rain gear.

What is the weather like in central Bali?

Central Bali, including Kintamani, Ubud and the nearby Tegallalang Rice Terraces and Tegenungan Waterfall, is characterised by warm temperatures, high humidity and frequent rainfall. Central areas tend to be cooler and wetter than Bali’s coastal areas, like Kuta and Seminyak, but more humid than the mountainous areas, like Mount Agung and Mount Batur.

Average daily temperatures in central Bali range between 22 – 31°C, with October and November being the hottest months. The region experiences higher rainfall than coastal Bali, with annual rainfall averaging between 2,400 – 2,700 mm – January is typically the wettest month, with long and heavy periods of rain. The dry season (May to October) tends to have lower rainfall and slightly cooler temperatures, making it a good time for visitors who want to avoid the chance of wet, muggy days. Either way, it’s always a good idea to be prepared and to take wet-weather gear when travelling to central Bali.
