TRAVELER FAQ

Answers before you leave.

What does the AirKorea color mean?

It summarizes official air-quality measurements. Open the detail to see the station, time and responsible pollutant rather than using the color alone.

Is one part of Seoul the same as another?

Not necessarily. Use the closest relevant station and time, then consider where the route will actually go.

Should I cancel the day?

Use the current official category, forecast, activity intensity and personal health advice to shorten, move indoors or cancel. Seek medical help for concerning symptoms.
