Hong Kong will have warmer but drier than usual weather in the coming three months following an almost rainless December, according to the latest analysis from the city’s meteorological agency.

The Observatory’s report, released on Friday, also noted that last month was slightly warmer than normal, with the monthly mean temperature at 18.5 degrees Celsius (65.3 Fahrenheit) – 0.3 degrees higher than the December norm.

Looking ahead, the Observatory forecast “normal to above-normal temperature” for January through March, attributing the trend to climate warming, which had led to a “significant long-term increase” in Hong Kong’s temperatures.

“Besides, the majority of climate models around the world forecast normal to above-normal temperature over southern China for January-March 2025. Hence, the temperature of January-March 2025 in Hong Kong is expected to be normal to above normal,” the Observatory said.

It also noted there would be a higher chance of “normal to below-normal” rainfall in Hong Kong between January and March, as suggested by forecasts from most other climate models.

Jeffrey Yeung Yat-long, a scientific officer at the Observatory, said last month that Hong Kong was especially dry because of the dry air in the lower atmosphere over the coast of southern China.

“Only traces of rainfall were recorded in the month, and it was one of 11 Decembers with just traces of rainfall since records began in 1884,” he said.
