Summer in Seoul is an interesting beast. It's hot, humid, and dominated by the monsoon season (jangma) from late June to mid-July. Average temperatures range from 25-30°C (77-86°F), often feeling much hotter with the humidity. If you don't mind the heat and potential rain, this season offers vibrant festivals and a different side of the city.

Honestly, it wouldn't be my first pick for the best time to visit Seoul for first-timers, mainly due to the weather. But if it’s when you can come, there’s still plenty to enjoy!

Early June can be quite pleasant before the full onslaught of the monsoon. Temperatures are warm, around 22-28°C (72-82°F), and the air isn't as sticky yet. Towards the end of the month, the humidity starts to climb, and scattered showers become more frequent.

July is peak monsoon. Expect heavy, intermittent rainfall, sometimes for days on end. Temperatures are high, 25-30°C (77-86°F), with very high humidity. It can be challenging for sightseeing.

• Best activities during monsoon:
  1. Museum hopping: National Museum of Korea, Leeum Samsung Museum of Art.
  2. Cafe culture: Seoul has an incredible cafe scene. Spend hours people-watching and enjoying delicious coffee. My current favorite is located near Hongik University Station (Line 2), Exit 3.
  3. Shopping: Underground shopping malls (Gangnam Station, Express Bus Terminal) are perfect for escaping the rain and heat.

The weather is fantastic – crisp, clear, and comfortably cool, with average temperatures ranging from 10-20°C (50-68°F). The entire city becomes a canvas of fiery reds, brilliant yellows, and deep oranges as the leaves change.

Pro Tips for Visiting Seoul

1. Embrace Public Transport: Seoul's subway system is incredibly efficient, clean, and easy to navigate. Get a T-Money card upon arrival (available at convenience stores) and load it up. It works on buses too!
