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.

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.
