Hong Kong has just emerged from an unusually warm October, with one of the highest monthly mean temperatures on record, according to the city’s weather authority.

The monthly mean temperature at the Observatory’s Tsim Sha Tsui headquarters was 26.3 degrees Celsius, 0.8 degrees above the normal figure of 25.5 degrees.

The reading was one of the highest on record since 1885. It trailed the 26.8 degrees in October last year, 26.5 degrees in October 2008, 26.4 degrees in October 1983 and 2006, and 26.3 degrees in October 1891.

Last month, two unprecedented “very hot” weather warnings were issued: on October 3, when the mercury at the headquarters hit 33.5 degrees – the highest for the month – and October 12.

Monthly total rainfall was 99.6mm, close to the normal level of 100.9mm.

Accumulated rainfall this year up to October tallied 2,540.9mm, about 9 per cent higher than the normal figure of 2,334.0mm for the same period.

All the “normal” values defined by the Observatory are an average of figures taken from 1981 to 2010.

Severe typhoon Khanun, which struck on October 15, was the fifth storm this year to prompt the issuance of a warning signal No 8 for the city, tying records set in 1964 and 1999. The signal represents the third level in a five-tier storm warning system.
