Seoul and Tokyo
The verdict for June

Early summer energy
+Plenty of daylight
–Rising humidity and rainfall
June becomes warmer and more humid as Seoul moves toward its summer rainy season.

Rainy season begins
+Hydrangeas, low crowds and softer hotel rates.
–Persistent rain and rising humidity make plans unreliable.
Cheap and quiet if you're happy to build an indoor-first trip.
Scores and crowd levels are my own judgement; temperatures are monthly averages. Higher scores are better: quieter, cheaper and more pleasant.
