Bali climate & weather

On a visit to Bali you can expect hot temperatures throughout the year, with temperatures ranging between 26-29°C, and only cooling slightly in the more central regions around Ubud and the mountains. Bali has two distinct seasons to bear in mind when deciding when to visit: the wet, falling between October and March, and the dry, spanning between April and September. The arrival of the dry season means hotter weather and an increase of sunny days, but with peak season coinciding with European summer holidays, it also means an increase in the number of visitors in July and August. Most visitors find that May, June and September are the best times to visit the island, when conditions remain warm and sunny, but there are fewer crowds in popular beach resorts like Sanur and Seminyak. 

Here’s our month-by-month guide to Bali’s weather and climate. 

Bali in January

January is typically Bali’s wettest month, though rainfall is not usually constant; you can expect hot sunny days with average temperatures of 26°C, but these will likely be interrupted with brief tropical downpours. In the higher regions around Mount Batur, temperatures are cooler and can drop to 15°C at night. 

Bali in February

The rainy season continues in February, with hot and humid days punctuated by intense periods of tropical rainfall. The temperatures stay at a consistent 26°C but with rough seas at this time, diving and snorkelling visibility around West Bali National Park are greatly reduced. 

Bali in March

March is another month where you can expect a high chance of afternoon rain showers. Days are hot, with temperatures increasing to an average of 27°C, and humidity can feel a little intense – for a respite, this is a great time to head inland to the cooler temperatures in Ubud. 

Bali in April

With Bali’s wet season coming to an end, the chance of rainfall this month starts to reduce significantly. You’ll enjoy mostly sunny days and temperatures will start to climb. With less winds along the coast, water visibility for diving and snorkelling off Bali’s east coast is very good. 

Bali in May

May is Bali’s hottest month, with temperatures averaging a maximum of 29°C. You can expect consistently dry and sunny weather, which makes for excellent diving and mountain climbing conditions. With the island not overly busy at this time, this is a great month to check for best value offers. 

Bali in June

One of the best months to visit Bali, June enjoys idyllic conditions with constant sunshine and a wonderfully warm average temperature of 27°C. You’re still not quite into the high season this month, so with visitor numbers fairly low you’ll enjoy less crowded hotels, beaches and restaurants if you visit now. 

Bali in July

July is another dry month, with an average of 4 days of rain and maximum temperatures of 27°C. With European school holidays approaching, July is a popular time of year to visit the island, so beach hotels, particularly in the popular resorts of Sanur and Seminyak, are likely to be busy. Water visibility for diving and snorkelling are excellent this month. 

Bali in August

Bali’s weather in August follows in similar fashion to July. With an average of 10 hours of sunshine a day, August is the sunniest month of the year – you’ll enjoy perfect beach conditions and hot temperatures that average 27°C. The south coast beach resorts are very busy this month, so for relief from the crowds as well as the hot weather, it might be worth heading towards the central region around Ubud. 

Bali in September

September is still a predominantly dry month with plenty of sunshine and clear skies, and temperatures that average a hot 27°C. One of the best months to visit Bali, the end of the European summer holidays mean that visitor numbers begin to reduce – the south coast beaches will become less crowded and you’ll experience fewer crowds when visiting temples and towns. 

Bali in October

October is officially the start of the wet season, so brief bursts of rainfall should be expected this month. Temperatures remain very warm in October, and you’ll still enjoy good water visibility around the protected dive spots of Menjangan and West Bali National Park. 

Bali in November

With the wet season now in full swing, you can expect an increased level of rainfall in November, particularly towards the end of the month. Sunny days are still frequent, and temperatures remain hot at an average of 27°C. Due to the wetter conditions, mountain climbing and trekking Mount Batur are not recommended this month.    

Bali in December

December in Bali has a high chance of rain showers, though you can still enjoy long periods of sunshine and very warm temperatures. With sea conditions worsening and the south coast beaches getting windier, water visibility is greatly reduced. Despite the wet weather, Christmas and New Year remain a popular time of year for visitors, so if you’re planning on visiting Bali now it’s well worth booking activities in advance.
