What is the weather like in Indonesia in May?

In May, Indonesia enjoys dry and sunny weather, as the country is well into its dry season. Temperatures are warm but with lower humidity compared to the rainy season. This month is an excellent time for outdoor activities such as hiking, beach outings, and sightseeing.

Is May a good time to visit Indonesia?

Generally, May is a great time to visit Indonesia. In many parts of the archipelago, including Bali, Java, and Sumatra, May marks the start of the dry season, characterized by warm temperatures and lower humidity. The weather tends to be pleasantly sunny with occasional short showers, making it an excellent time for beach activities and exploring cultural sites without the peak tourist crowds. 

Swimming and water sports are usually enjoyable during this period due to calm seas and clear waters. You can enjoy snorkeling around coral reefs, hiking Mount Batur for stunning sunrise views, or visiting traditional markets. 

However, you should be prepared for the occasional rain in more tropical regions like Sulawesi or Papua, where May can still see some lingering showers from the wet season.

What about the crowd & cost?

May has a great balance between weather and crowds and costs. 

The weather in May is generally pleasant, with the dry season just beginning, and you can expect comfortable temperatures and reduced rainfall.

If you’re hoping to get by with spending less, you might want to consider other months during the shoulder season, like April or early September. These months will be slightly more unpredictable weather-wise, but could be slightly more cheap as well.
