08Editor's notes
What the numbers don't tell you
July is the jangma monsoon, with heavy rain and grey skies in the first three weeks, on about fifteen days, then intense heat and humidity above 30 °C. Korean school holidays begin late in the month. It is the cheapest month for hotels, and the city's underground shopping streets, museums and cafés keep the rain manageable. Flash flooding in low-lying districts occurs in a wet year.
The Boryeong Mud Festival on the west coast draws foreign visitors in mid-July. Air quality is at its best of the year in the rains. The Han River pools open in July. The Seoul International Cartoon and Animation Festival fills the first half. For the hottest month and Liberation Day, see August.
