Bali Weather Guide: Month By Month

One of the first questions people ask when considering Bali for a holiday destination is, “When is the best time to go?” We get these type of questions from people looking to rent our gorgeous Bali villas.

Obviously, the answer you get is going to depend on who you ask. Seasoned Bali travelers and Bali locals are likely to respond with something like, “Are you kidding? It’s Bali. There is no bad time to go!”

Even though Bali has a year round temperature of 80 degrees and enjoys bright sunny days most of the time, there are some brief periods of wonky weather, like the wet season, that some tourists may want to avoid.

We have created this brief overview of Bali weather conditions year round so that you can know a bit about what to expect before booking your trip.

April-September

Dry Season

April to September in Bali is the dry season, meaning rainfall amounts are minimal, temperatures are steady and the sun is always ablaze in the sky. It’s also the high season, in terms of travel, when most tourists flock to Bali. High season also means that prices on pretty much everything are higher this time of year, as opposed to prices in the off-season.

April

By April, humidity levels have bottomed out to around 65%, which makes for cooler, more enjoyable days. Even though the temperatures can rise in to the low 90s during April, the lower humidity helps with how hot the temperature actually feels.

May

May temperatures in Bali are pretty consistent with Aprils, hovering around the 80 degree mark. Humidity levels remain low and daylight hours stretch to about nine, on average. Clear skies prevail in May, as the rainy season becomes just a memory at this point.

June, July and August

Humidity levels are at their lowest points during June and July and the temperatures remain at a comfortable 80 degrees, on average. The days are long – and sunny – during these months, which gives ample time for all your outdoor activities. The clear skies create the perfect backdrop for amazing tropical sunsets over the ocean and night time temperatures are still quite enjoyable as well. June tends to be the best month for water surfing, as the waves are at their peak this time of year. While August tends to be the driest month of the year, with an average reported rain total of just over an inch in a half, spread out over the course of three days. June, July and August are the busiest travel seasons in Bali so expect crowds. Big ones. This perfect weather during these months is a big reason why people keep coming back to Bali.

September

September is a transitional month in Bali, as most tourists from the summer rush are heading home as the high season, dry season and peak seasons come to an end. Even though it’s a transitional month, September still has very mild, comfortable days with lots of sun, even though humidity levels are on the increase.

October-March

Wet Season

As humidity levels creep up and the crowds thin out, Bali’s wet season begins in October and runs through the end of March. Prospective tourists should not assume, however, that, during this time, it’s going to rain every day, all day long. That’s not the case. Usually when it rains in Bali during the wet season, it’s just a passing thunderstorm in the afternoon or night time hours, not a complete vacation washout. Even though the temps feel warmer and the air is heavier, the wet season in Bali can still be enjoyable, too – especially since the crowds have thinned out and gone home.

October

October is one of the hottest months in Bali, with average daily temps hovering around 90 degrees. Sunshine amounts decrease a bit, but still average about nine hours each day. The hotter temps of October are the perfect excuse for cooling off in the ocean along one of Bali’s fabulous beaches.

November

Humidity levels continue to rise during November and the daily sunshine hours are reduced from nine to about seven. Daily rain showers are common and to be expected, but not to the point of ruining any plans you may have.

December

December is the onset of monsoon season and as expected, there may be entire days of rain. However, when the rains come in the mornings, the afternoons are usually quite sunny so it’s still a great trade off. Because of the monsoon season, you will definitely notice the humidity levels on the rise. On a side note, the ocean is warmest in December, but still feels quite nice when cooling off.

January and February

January is the wettest – and hottest – month in Bali, with rainfall totals averaging well over 18 inches. Hot and sticky are the best words to describe it. February is pretty much a repeat of January, weather-wise so just expect heat, humidity and rain – in large doses. Plan accordingly!

March

March is when the monsoon season draws to an end, with decreasing rain chances. Temperatures remain just as hot as January and February, but begin to slowly slack off toward the end of the month, when the dry season begins and the Bali weather cycle starts all over again.

What should you pack for Bali?

As expected you should really pack lightly but this will depend on where you are on the island and what time of year your there. As a guide start with this:

  • Swimwear
  • Board shorts
  • Sun glasses
  • Sun creams and hats as well as UV rash vests for the kids
  • All your wear should be casual even if your going out for dinner – most places are relaxed & chinos and a collared shirt is fine
  • For the kids again, pack light clothing and if it’s the wet season take a raincoat.
  • It can get cool at nights in July, August and September so take a shirt or jumper if your going out at night
