A typhoon passed a few miles to the South of the Observatory on a WNW track on the morning of July 25. By this time its violence had abated, however. It produced only a moderate gale at Hong Kong. Another typhoon which passed about 70 miles, to the South of the Observatory in the forenoon of August 20, on a westerly track, produced a violent gale at Hong Kong. The maximum squall velocity was at the rate of 116 m.p.h. at 15h. 23m. A typhoon formed to the North of the Paracels on the morning of November 20.

A depression formed near Pratas on the morning of August 30 and passed between Hong Kong and Gap Rock in the afternoon. The wind velocity increased from 11 m.p.h. at 13h. to 28 m.p.h. at 14h. and a squall at the rate of 57 m.p.h. occurred at 14h. 23m. By 19th. it was dead calm.
