Goyang-si Weather in October

October weather

October feels like a lovely time to explore Goyang-si. Days are mild, with highs around 19°C, and evenings cool to about 10°C. Rain falls on around seven days, so most outings won't be washed out. You'll get plenty of daylight for a walk or a day trip, too.

The comfortable weather suits the paths around Ilsan Lake Park and the gardens at Haengjusanseong Fortress. It's also a good month for outdoor sightseeing before November's cooler days arrive. Skip long afternoons in open fields if rain is forecast, and keep an indoor stop in mind, such as the National Women's History Exhibition Hall.

Festivals and holidays

Goyang's Autumn Flower Festival is held at Ilsan Lake Park, though its dates can vary. If it's running during your visit, expect flower displays and more people around the park. Check the festival dates for your travel year before building your plans around it.

October also has public holidays on National Foundation Day and Hangul Day. Chuseok, Korea's major harvest holiday, can fall in September or October. When it does, travel and opening hours may change as people visit family. If you hate crowds, choose a weekday for Ilsan Lake Park and avoid travelling across Korea during Chuseok.

Crowds and local tips

October is one of Goyang's best months, alongside May, so it isn't a quiet secret. Still, it's outside the summer holiday period, and weekdays are generally calmer than festival weekends. Costs can vary by event and demand; don't assume every October stay will be cheaper than summer.

At Ilsan Lake Park, use Jeongbalsan Station and walk to the lake rather than relying on a taxi near festival traffic. You can pair the park with a meal around nearby La Festa, an open-air shopping and dining area. For a quieter visit, go on a weekday and follow the water away from the festival displays.
