Semarang Weather in August

August weather

August is warm and mostly dry in Semarang. Afternoons reach 33°C, while evenings cool to around 23°C. Rain falls on about six days, so showers are less of a regular interruption than in wetter months. July is cooler and slightly wetter; September gets hotter and rainier.

You'll have plenty of sunshine for Kota Lama's old streets and the grounds around Lawang Sewu. The midday heat can make long walks feel sticky, though. Save outdoor sightseeing for morning or late afternoon, and avoid a long exposed walk during the hottest part of the day. August is also a good month for a trip to nearby Jepara, where the weather is rated even better.

Independence Day

Indonesia celebrates Independence Day on 17 August. Semarang marks the occasion with ceremonies and local games, often called lomba. These can include sack races and other friendly competitions. You may spot celebrations in neighbourhoods, but events vary by year and area.

If you hate crowds, avoid lingering around ceremony spots on the day itself. The celebrations are a lively way to see local life, but they're not a city-wide festival with one central venue.

Crowds and practical tips

August is one of Semarang's best months for weather, but it's usually less busy than the July school-holiday period. Independence Day can draw local crowds, while prices are generally steadier than during peak holiday travel. September is a quieter alternative for some visitors, but it's hotter and wetter.

Travelling with kids? Kota Lama's shaded cafés make a useful break between short walks. At Lawang Sewu, visit earlier in the day so you can explore the historic rooms before the heat builds. For an easy local meal, try lumpia Semarang, a spring roll filled with bamboo shoots and other ingredients. You can find it around the city centre.
