Semarang Weather, When to Go and Climate Information

(Semarang, Central Java, Indonesia)

The Indonesian island of Java is just a short distance to the south of the equator, and this means that the climate in Semarang is both hot and tropical, with high year-round temperatures usually topping 30°C / 86°F by day and 22°C / 72°F at night.

Between May and September (the dry season), rainy weather in Semarang is infrequent and minimal to say the least, and for sightseers, this really is the best time of the year to pay a visit to Indonesia. However, do bear in mind that the relatively humid climate can make the temperatures feel much hotter, and so early morning sightseeing is often advisable.

Seasonal Climate Variations / When to Go

Many locals in Java refer to Semarang as the 'hot city', due to its especially sunny weather and fine climate. However, things begin to change dramatically in October, when tropical monsoons start to make an appearance, directly affected by the Asian and Pacific Ocean air circulation.

The rainy season in Semarang reliably falls between October and April, with heavy downpours and showers generally alternating with sunny days. Therefore, although there is a lot of rain at this time of the year, there is also plenty of scope for sightseeing if you have a flexible itinerary.
