Weather Underground of Hong Kong (Chinese: 香港地下天文台; pinyin: xiānggǎng dìxià tiānwéntái) is a non-profit website established in 1995 and directed by Clarence Fong Chi-kong. The website provides a wide range of information related to weather and climate. Air temperature, relative humidity, barometric pressure, rain, and wind chill can be found on the site.
