Goyang-si Weather in April

April weather

April feels like a proper step into spring in Goyang-si. Days reach about 16°C, but evenings can drop to 5°C, so the temperature changes noticeably between a sunny afternoon and dinner time. Rain falls on around seven days, and there's plenty of daylight for a full day out.

It's a good month for walking around Ilsan Lake Park or exploring Haengju Fortress, where you can enjoy the views without summer heat. Rain can interrupt a long outdoor visit, though, so keep indoor stops like the National Women's History Exhibition Hall in mind.

Flowers and spring crowds

The Goyang International Flower Festival is held at Ilsan Lake Park, usually around late April and into May. Its exact dates can vary, so check the festival schedule before travelling. Cherry blossoms also make spring walks appealing, though bloom timing shifts with the weather.

If you hate crowds, visit the lake park on a weekday rather than during the festival. April is generally a shoulder-season choice, while May and October are among Goyang's best-known months to visit. You may find fewer visitors and lower accommodation prices than in those peak months, but festival weekends can feel busy.

Getting around Goyang-si in April

Travelling with kids? Ilsan Lake Park has wide paths, open lawns and room for a relaxed afternoon, though the festival crowds may make it harder to move around. For a quieter outing, head to Haengju Fortress and enjoy a walk through its historic grounds.

A handy local tip: take the Seoul Metro Line 3 to Jeongbalsan Station for Ilsan Lake Park, then follow signs towards the festival grounds. That saves you from guessing which part of the large park to reach. For dinner nearby, try dakgalbi, spicy stir-fried chicken, around the Madu or Jeongbalsan area.
