In summer 2013, temperatures continue to remain above normal in many parts of Japan, especially in western Japan. Ten-day mean temperatures averaged over western Japan were the third highest on record for three consecutive ten-day periods from the middle of July (11 – 20 July, 21 – 31 July and 1 – 10 August) in the JMA records since 1961. Since around 8 August, temperatures have been well above normal almost all over Japan and more than 3˚C above normal at a large number of observation stations mainly on the Pacific side in eastern and western Japan. On 11 August, the daily minimum temperature at Tokyo was as high as 30.4˚C. It was the first time for the temperature in Tokyo to remain over 30˚C for all day long since the daily observation started in 1875.

Since July, precipitation amounts continue to be below normal on the Pacific side in eastern and western Japan and in Okinawa/Amami. The precipitation amount from 1 July through 12 August was as little as 0.0 mm in Naze (Kagoshima Prefecture). In summer 2013, many parts in Japan, especially in western Japan, experience very high temperatures, while precipitation amounts are below normal on the Pacific side in eastern and western Japan as well as in Okinawa/Amami. Four stations recorded temperatures reaching or exceeding 40˚C, among which Ekawasaki (Kochi Prefecture) hit 41.0˚C, a new country record high temperature, on 12 August. >> More
