Seoul in September
Average Temperature: 27°C
Traveling to Seoul in September is a pretty nice experience because the city starts to cool down from the hot summer, making it much more comfortable to explore. The air feels fresher, and you get to enjoy the beautiful changes in nature as the leaves begin to hint at autumn colors. It's a great time to stroll around the vibrant neighborhoods like Hongdae or Insadong without the overwhelming summer crowds, and the outdoor cafes and street food markets are really lively. Plus, September often brings some cultural festivals and events, so you might catch a traditional performance or a cool art show while you’re there.
That said, September can be a bit unpredictable weather-wise. Sometimes you get the tail end of the rainy season, so packing a light rain jacket or umbrella is a smart move. The city itself is a fascinating mix of ultra-modern and historical, so whether you’re into cutting-edge technology, K-pop culture, or ancient palaces, there’s always something to keep you busy. Seoul’s public transport is super efficient, making it easy to get around and see plenty in a short amount of time. Just be ready for some early autumn humidity and occasional showers, and you’ll have a pretty rewarding visit.
