Observed Climate Change in Hong Kong

Mean sea level

Tide gauge records in Victoria Harbour since 1954 demonstrate an unambiguous rise of the mean sea level during this period. There was a rise of the sea level from 1990 to 1999 and a moderate decline thereafter. The trend is similar to that observed by satellite remote sensing over the South China Sea and that recorded by tide gauges at other coastal stations in the region. On average, the mean sea level in Victoria Harbour rose at a rate of 30 mm per decade during 1954-2015.
