If you're willing to plan for a few rainy days and don't mind spending a bit less time on the beach, I think that visiting Bali during the rainy season is perfectly fine. It's cheaper, less crowded and less congested.
We'd recommend to avoid visiting during the December holidays as not only is this peak rainy season, but crowds are also heavy. Our personal pick would be to visit Bali during the shoulder months, May, June or September, to avoid the rain and the crowds.
The island receives most of its annual rainfall during this time, and it can be quite heavy at times, but usually, it does not rain all day, usually, there are short spells of rain that might last a couple of hours in the afternoon and during nights.
If you visit Bali during rainy season, a rain jacket is a must. However, if you're traveling outside of wet season, then you will not require a rain jacket.
When planning a trip to Bali, I recommend planning to spend at least 5 days in Bali. However, 10 days to 2 weeks would ultimately be best, allowing you to explore everything the island offers. You can also go for as little as 3 days, but you can only visit one location. Bali is the perfect honeymoon destination.
Despite some challenges, Bali has a lot to offer. Its rice paddies, waterfalls, temples, local culture, and the friendly Balinese people make it a place worth exploring. As with any destination, it's important to manage your expectations and see it for what it is.
The best time to visit Bali is between April and October, the island's dry season. Although the weather is ideal for travellers, the island is also subject to soupy, humid days throughout the year. Many shops offer sales and promotions; restaurants are less crowded in those mid-season months.
The Dry Season between the months of May – September have the lowest humidity. May is usually the hottest month in Bali with an average temperature of 28°C (82°F) and the coldest is January at 26°C (79°F) with the most daily sunshine hours at 9 in April.
There are no specific vaccine requirements for entry into Bali, however there are a number of factors to consider when deciding whether or not to take precautions and get vaccinated against diseases prevalent in Bali and surrounding South East Asian countries including Indonesia.
Recently, Bali's Governor announced the introduction of a $10 tourist tax, which is expected to take effect in mid-2024. The tax will be a one-time fee that foreign visitors must pay electronically upon arrival to the island.
The cheapest times for accommodation in Bali coincide with the wet season, October through to March. During this time, tourism numbers are lower so hotels in Bali are cheaper due to a lack of demand and act as a draw to bring more people in.
