Tokyo Weather in August: What to Wear & Expect
August is the hottest month of the year in Tokyo. Central Tokyo's average high is 31.3°C, but in recent years days above 35°C are not unusual. Many nights stay above 25°C and humidity is high, so beating the heat is a must. In mid-August, Obon (a holiday period when many people travel to their hometowns) crowds the transport network. To escape the heat, we recommend Karuizawa, Oku-Nikko or Kusatsu.
