Monthly Forecast for January 2025

Hong Kong is expecting:

1.	near-normal temperature
2.	normal to below-normal rainfall

Additional information:

Dry continental airstream is expected to prevail over the coastal areas of Southern China for most of the time in January 2025. Generally dry weather with below normal rainfall is expected over the region in the early part of January 2025.

Assessment (as of 31 December 2024):

In the past month or so, sea surface temperatures of the central and eastern equatorial Pacific were near normal on the whole. Based on the latest oceanic observations as well as forecasts by a number of climate models around the world, the sea surface temperatures of the central and eastern equatorial Pacific are likely to be normal to below normal for the rest of winter 2024/25 and spring 2025.
Taking into consideration of the impacts of global warming and latest ENSO status, different climate model forecasts and other objective forecast guidance, the temperature of January 2025 in Hong Kong is expected to be near normal and the chance of normal to below-normal rainfall in the month will be higher.
