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



Additional information:
  1. The confrontation of the northeast monsoon and the humid maritime airstream over southern China is expected to bring wetter than normal weather to Hong Kong in the first half of March 2025.
  2. Temperature-wise, with rainy weather, the temperature in Hong Kong is expected to be normal to below normal in the first half of March 2025. The temperature will rise towards the latter half of the month. Overall, the chance of near-normal temperature of March 2025 in Hong Kong will be slightly higher.

Assessment (as of 28 February 2025):
  1. 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 spring this year.

  2. 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 March 2025 in Hong Kong is expected to be near normal and the chance of normal to above-normal rainfall in the month will be slightly higher.
