What Is the Weather Like in Semarang?

Semarang has a warm climate all year, so the main difference between months is not cold versus warm. The real question is rain, humidity, storms, cloud cover, and how heavy the air feels during the wettest part of the year. The Semarang climate by month shows average highs from about 88F (31C) in the coolest part of the year to about 94F (35C) in the hottest part. Annual precipitation averages roughly 80.0 inches.

Weather in Semarang changes the feel of the city because this is a place where comfort depends on more than the number on a forecast. A mild month can make metro transfers, neighborhood walks, outdoor meals, and photography feel easy. A difficult month can make the same itinerary feel slower, sweatier, colder, wetter, or more dependent on indoor breaks.

Best Month to Visit Semarang for Weather

June is the best month to visit Semarang for weather in a typical year. Average daytime highs are near 86F (30C), while nights are around 73F (23C). Precipitation averages 3.6 inches, so the month is usually more comfortable than the wetter, hotter, or colder parts of the year.

What makes June stand out is balance. It is not necessarily perfect every day, but it usually gives travelers the best combination of outdoor comfort, manageable weather risk, and enough flexibility for a first-time trip. If hotel prices or crowds rise during this period, that popularity is at least partly weather-driven.

Worst Month to Visit Semarang for Weather

February is the worst month to visit Semarang from a pure weather perspective. Average highs are around 83F (28C), and nights are near 76F (24C). The month also brings heavy rain, averaging about 13.4 inches, which can make long outdoor days less comfortable.

Rain is the main problem. The month is not impossible, but showers and damp conditions can interrupt outdoor plans and make transit transfers less pleasant. Lower hotel prices or fewer visitors can make February acceptable for flexible travelers, but it is not the month I would choose for the best weather in Semarang.
