About Us

Started operation on 15th August 2007, Hong Kong Weather Watch (HKWW) is a non-governmental meteorological interest site which integrates information from many official sources and presents it in an easily interpreted way for users' reference. As of February 2017, the site can be divided into five parts:

Our site mainly covers weather information about Hong Kong, with the exception of 1) Tropical Cyclone Watch in which related information is provided whenever there are tropical cyclones in the Northwest Pacific Ocean (The part of Pacific Ocean west of 180 degrees longitude, North of the equator), and 2) Part of Astronomical Information which is provided globally. Part D focuses on activities held by HKWW or those that HKWW participates in, and Part E contains other useful meteorological weblinks and information about HKWW.

Most of the contents in Hong Kong Weather Watch are updated automatically, while tropical cyclone reports are normally updated once per day manually except at times when the tropical cyclone(s) concerned is/are posing a direct threat to Hong Kong.

Should you have any enquiries, comments or suggestions, please email them to hkwwinfo@gmail.com. Your valuable comments are vital to our successful development.

The results of "Astronomical, Geographic and Meteorological Events of 2009" Election is announced. We thank all for your participation. The top three events are:

  1. (19/7) Typhoon Molave made landfall at Longgang District of Shenzhen City, and it was only 40 kilometres from the Observatory at its closest point of approach. The Observatory issued the #9 Increasing Gale or Storm Signal for the second time in as many years. Molave is the strongest typhoon to make a "direct hit" since Typhoon Dujuan in 2003.
  2. (7-8/8) Typhoon Morakot made landfall at Hualien, producing winds of force 13. Morakot weakened into a severe tropical cyclone in Taiwan, and made landfall again at Fujian on August 9. The southwesterly airstream induced by Morakot triggered the heaviest rainfall in many areas in Taiwan since 1959, with Alishan recording 2500 mm of rainfall in just three days, and the death toll exceeded 600 as a result.
  3. (14/9) [Tied for second place] Typhoon Koppu passed at about 130 kilometres from the Observatory; the #8 Gale or Storm Signal was issued at 5:55 p.m. and lasted for 16 hours 20 minutes. Winds were very strong that night in the territory; coupled with high tides the next morning, low-lying areas like Tai O were flooded. Koppu made landfall at Taishan, Guangdong on September 15, creating winds of up to force 14. The storm is responsible for at least 9 deaths and 9 others went missing.

"2009 年天文、地理及氣象大事選舉" 結果公佈,謝謝各位的參與。首三位事件為 :

  1. (19/7) 颱風莫拉菲在中國廣東省深圳市龍崗區南澳街道沿海地區登陸,其中心於香港天文台北面 40 公里掠過,天文台發出九號烈風或暴風信號,是 2008 年以來第二次。莫拉菲為自 2003 年颱風杜鵑以來正面吹襲香港的最強颱風。
  2. (7-8/8) 颱風莫拉克在台灣花蓮縣登陸,登陸時颱風中心附近最大風力13級。莫拉克於台灣減弱為強烈熱帶風暴,並於 9 日再度登陸福建省霞浦縣。莫拉克引進西南氣流,台灣經歷 50 年來最嚴重的雨災,阿里山於三天內雨量超過 2500 毫米;總計造成超過 600 人死亡,是為 "八八水災"。
  3. (14/9) [並列第二位] 颱風巨爵於本港 130 公里外掠過,天文台於下午 5 時 55 分發出八號烈風或暴風信號,共維持 16 小時 20 分鐘。當晚本港風勢強勁,適逢 15 日凌晨大潮,大澳等低窪地區出現水浸。巨爵於 15 日清晨在中國廣東省台山市北陡鎮沿海地區登陸,廣東省最大風速達 14 級。它造成至少 9 人死亡,9 人失蹤。

1) An upgrade of PHP version was made to this site's server earlier today. However it is found that some important libraries and methods are missing. Therefore, you may see warning messages when some of our programs are run, which is due to the problem stated above. My apologies for the inconvenience, and I may switch to another server if problem persists. Please stay tuned for the latest information.

2) The permanent link for the "multi-agency tracking map" has been changed from http://www.hkww.org/weather/agencytc/ to http://203.80.210.7/~hkmccnete4/david/agencytc/. I have discontinued updates to the former address, with immediate effect.

2) "各站預測路徑圖" 的網址已由 http://www.hkww.org/weather/agencytc/ (已停止更新) 更改至 http://203.80.210.7/~hkmccnete4/david/agencytc/
