Goyang-si Weather in July

July: hot and soggy

Goyang-si feels hot, sticky and often wet in July. The average high is 28°C, and humidity reaches 84%. Rain falls on 19 days, with 360 mm across the month. That's much wetter than June, and even August is less rainy. Cloudy skies and limited sunshine can make outdoor plans feel gloomy.

You can still enjoy Ilsan Lake Park between showers, or spend a rainy afternoon at Aqua Planet Ilsan. Long walks and cycling around the lake are less appealing when paths are slick and the air feels heavy. Keep outdoor sightseeing flexible, and avoid planning a full day outside.

Festivals and summer holidays

There isn't a major annual Goyang festival to count on in July. The city's well-known Goyang International Flower Festival takes place in spring, not summer. South Korea marks Constitution Day on July 17, but it isn't a public holiday, so don't expect a nationwide day off.

School summer breaks bring more families to indoor attractions such as One Mount and Aqua Planet Ilsan. If you hate crowds, try the lake park instead, especially when the weather turns wet.

Crowds, costs and local tips

July is summer high season, so family attractions can feel busier and accommodation may cost more than in quieter months like May and October. It's not the best month for a relaxed outdoor city break, but indoor stops make a practical backup.

At Ilsan Lake Park, use the covered paths and nearby cafés to wait out a downpour. If you're visiting One Mount, put its indoor water park on your rainy-day list rather than relying on outdoor plans. The wet weather can change your day quickly.
