May weather forecast
Indonesia

May in Indonesia signals the onset of the dry season, with a significant decrease in rainfall and an increase in sunnier, drier days. The average temperature during this month remains consistent with previous months, generally between 23°C (73.4°F) and 28°C (82.4°F). In high-altitude regions, such as the highlands of Sumatra and Papua, temperatures can be cooler, particularly at night.

When considering rainfall, May typically brings drier conditions to most parts of the country. For instance, in Jakarta, the average rainfall significantly reduces to about 90mm (3.54"), signifying a clear shift towards drier weather. Similarly, in Bali, rainfall averages around 80mm (3.15"), significantly less than the wet season months.

Comparing May to April, there is a noticeable change in weather conditions as the rainfall decreases and the frequency of dry, sunny days increases. As Indonesia progresses into June, the dry season becomes more established, with even lower levels of rainfall and humidity expected throughout the country.

Travellers planning a trip in May can look forward to excellent weather for outdoor activities, such as hiking, beach visits, and exploring the diverse cultural and natural attractions that Indonesia has to offer. The landscapes remain lush and vibrant, and tourist crowds are still relatively low compared to the peak travel season. As the risk of flooding and landslides recedes with the wet season, this period allows for easier travel and exploration across the country.
