Hong Kong will experience 100% relative humidity with warmer and wetter weather this week

Hong Kong will experience warm and wet weather over the week ahead as relative humidity levels are set to reach as high as 100 per cent, according to the forecaster.

The Hong Kong Observatory said temperatures on Tuesday and Wednesday would remain cool at 14°C with a few rain patches under the impact of the northeast monsoon and upper-air disturbances, adding they would gradually get warmer from Thursday.

“With the departure of upper-air disturbances and under the influence of a humid maritime airstream, temperatures will rise progressively over the coast of Guangdong in the latter part of this week and early next week,” the Observatory said.

“There may be damp days over the weekend.”

According to the latest nine-day forecast, the city’s relative humidity will be between 75 and 95 per cent from Wednesday to Friday and rise to as high as 100 per cent on Sunday and Monday.

The temperatures will also gradually reach as high as 25°C on Sunday.

But the Observatory said another northeast monsoon was expected to affect southern China again next week and lead to a fall in temperatures.
