香港天氣觀測站於 2007 年 8 月 15 日開始運作，為一個民辦氣象興趣網站，旨在讓用者能快速和簡潔地獲得所需的天氣資訊。截至 2017 年 2 月，本站可分為五個部分：
除了熱帶氣旋和全球部分的天文資料外，本站主要覆蓋香港的天氣資訊。至於熱帶氣旋方面，每當西北太平洋 (180 經度以西；赤道以北) 有熱帶氣旋形成時，本站就會對該熱帶氣旋發出報告。第四部分包含本站所舉辦及參與的活動之資料，而第五部分則提供世界性的氣象資料，同時亦較為適合非香港的用者。

"2010 年天文、地理及氣象大事選舉" 結果已於此頁公佈，多謝各位參與。首三項事件分別為：
The 42nd Typhoon Committee annual meeting was held earlier this year. It was decided that three of the tropical cyclone names currently on the list, including MORAKOT, KETSANA and PARMA, will be retired as a result of the intensive damages that they have caused. The replacement names will be determined in next year's meeting. Please click here to take a look at the revised list.
The 128-km-range radar image is added.
A page on "Air Pollution Levels" is added. This page shows the concentration of various pollutants over Hong Kong with their respective sub-indices, and can also be accessed through the "Details" hyperlink in the "Air Pollution Index" section on the main page.
The JTWC has recently issued best track and intensity data for tropical cyclones in 2009. These revised intensities are now available in our "TC Archive" page, and the best track data can be retrieved at this site. Also, as Typhoon Lupit was not a category 5 typhoon in real-time data, we will not provide review on this tropical cyclone.
HKO's temperature data for automatic weather stations at Wong Tai Sin, Happy Valley and Kwun Tong are added in our "Regional Weather" section/page.
The results of "Astronomical, Geographic and Meteorological Events of 2009" Election is announced. We thank all for your participation. The top three events are:

Happy New Year! As a result of poor weather conditions, the lunar eclipse that occurred earlier today was not visible in Hong Kong. However, a partial solar eclipse will be visible in the territory on January 15 and two visible partial lunar eclipses will occur on June 26 and December 21 respectively. Click here for our page on "Annular Solar Eclipse of January 15th, 2010".

A new look for our "Delta P Values" column.
The page "Official TC Track Info" is added. It shows all named tropical cyclones in NW Pacific and the South China Sea and includes track and intensity forecasts from major official agencies.
For the news article on the waterspout spotted in Hong Kong waters on Aug 19, please refer to the following web page : http://www.info.gov.hk/gia/general/200908/19/P200908190213.htm.
A penumbral lunar eclipse will occur on Aug 6 but is not visible in Hong Kong. For more information, please refer to NASA's PDF document on this eclipse: http://eclipse.gsfc.nasa.gov/LEplot/LEplot2001/LE2009Aug06N.pdf.
The finalized reviews of tropical cyclones LINFA, NANGKA and the preliminary reports of tropical cyclones SOUDELOR and MOLAVE are now available in this page.
Hong Kong can witness a large-scale partial solar eclipse on July 22nd if weather permits, and live webcast will be available at that time. For more information, please refer to our special page "Total Solar Eclipse of July 22nd, 2009" and animation of the eclipse. Furthermore, we have added pages on "Eclipse Q&A", "Eclipse Glossary", "Solar Eclipse Dates and Numbers" and "Solar Eclipse Calculator" for your reference.
We have added "Rainfall distribution & RADAR image" in "Warning(s) in Force" column on the mainpage, which will be activated whenever the thunderstorm warning and/or rainstorm warning signal are/is in force.
Dr. Lee Boon-ying was appointed the (acting) Director of the Hong Kong Observatory, replacing Mr. Lam Chiu-ying who is about to retire. [Organizational Chart] [Director's Blog]
The Observatory announced earlier that two more categories, "severe typhoon" and "super typhoon", are to be introduced to the tropical cyclone classification system from this year (Details). We will stay with our current system, but a conversion chart will be provided later for reference. Click here for our current tropical cyclone classification system.
A "share" functionality ( ) is added for you to share the page via other websites (e.g. Facebook), and you can bookmark that page via that button.
A penumbral lunar eclipse will be visible in Hong Kong from 8 to 12 tonight (9th Feb) if the weather permits (View it LIVE on web!). Please refer to HKO's press release for more details.
"Air Pollution Index" column is added on the main page.
"Earthquake Information" column is added on the main page. This column shows information on significant seismic activities in the past 24 hours.
As the beta test result of "Tropical Cyclone Strike Probability" is unsatisfactory, this product will be temporarily removed from our site from now on.
Our site resumes normal service on 1st September. From now on, we will turn to the typhoon mode when bandwidth usage surges so as to reduce the load of the main server.
An earthquake of mangitude 7.8 occurred in Sichuan Province at 2:28 p.m. local time today. The Observatory has received reports from local residents and this tremor was also recorded by the Observatory. See here for more.
HKWW presents to you a new look of our website! All frames that appeared in the previous version have been combined into one and you can now navigate through pages using the navigation bar near the top of each page. If you have any suggestions about this theme (or if you find any bugs), please email to me at email@example.com. I hope you enjoy this new theme!

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://www.hk-mcc.net/david/agencytc/. I have discontinued updates to the former address, with immediate effect.
