The U.S. National Oceanic and Atmospheric Administration recently announced that the globally averaged temperature over land and ocean surfaces in summer (June to August) 2015 was the highest ever recorded for the globe since 1880.
Hong Kong also experienced the hottest summer ever since records began in 1884 with the mean temperature for June to August 2015 reaching 29.4 degrees, breaking the previous record of 29.3 degrees set not so long ago last year.
June 2015 was actually the hottest June on record (Table 1). Under the subsidence effect associated with Typhoon Soudelor, the temperature at the Hong Kong Observatory soared to a record-breaking 36.3 degrees on 8 August 2015, beating the previous extreme of 36.1 degrees set in 1990. More details on the record-breaking temperatures this summer are summarized in Table 2.
