Daily Weather Report and Map. A weather map of the Far East for 6 a.m. of the 120th meridian, and the Daily Weather Report (containing meteorological observations, usually at 6h. and 14h., from about 40 stations in China, Indo-China, Japan, the Philippines, and Borneo), and daily weather forecasts for Hongkong to Gap Rock, the Formosa Channel, the south coast of China between Hongkong and Lammocks, and between Hongkong and Hainan, were issued as in former years. Copies of the map were exhibited on notice boards at the Hongkong Ferry Pier, the Blake Pier, and the Harbour Office. One copy was sent daily to the Director of the Meteorological Observatory, Macao. Forty copies of the Daily Weather Report were distributed to various offices, etc., in the Colony, and a copy was sent daily to the Director of the Meteorological Observatory, Macao. Copies were sent every week to Lieutenant Commander Pradiyat, Royal Siamese Navy.
A charge of $10 a year is made for supplying private firms and individuals with the Daily Weather Report, and $36 for the Weather Map. No map was published on February 3, 21, and 24, March 4, 8, and 17, April 2 and 7, May 5, 12, and 26, June 20, July 2, 3, 5, and 7, and December 25, owing to the late arrival of the weather telegrams. On many other occasions the map, though published, contained but meagre information.
The weather forecast is telegraphed daily to the Cape d'Aguilar Wireless Station in time for distribution at 1 p.m.
